Ethernet Remote Master (ERM)

The Ethernet Remote Master (ERM) module provides a low-cost, high-speedEthernet Remote I/O link for DirectLogic 205/405 PLC systems and WinPLCsystems. The ERM connects the local CPU base(s) to the ethernet remote slave

modules via a 10BaseT (twisted pair, copper wire) or 10BaseFL (fiber optic)Ethernet link. Each ERM module can support up to sixteen slaves when used inDirectLogic 205/405 PLC systems. When used in Think & Do WinPLC systems, alimitation of one ERM with one slave applies per system.

H2ERM H2ERMF H4ERM H4ERMF

The following Ethernet Base Controller (EBC) slave modules and EthernetInterfaces for AC Drives are supported by the ERM module. The remote I/O networkmay consist of a combination of these slaves. The ERM module can support up tosixteen slaves when used in DirectLogic 205/405 PLC systems. When used in Think

& Do WinPLC systems, the ERM module is limited to supporting one slave.The EBC slave updates all of its I/O data (including analog I/O) internally at a highrate that is independent of the rate that the ERM may poll the EBC for its I/O data.This allows the ERM to read the most current I/O data regardless of PLC scantimes or other slave I/O cycle times.

How the PLC CPU Updates Remote I/O Points

The PLC CPU, ERM and Remote Slave (EBC) modules work together to update theremote I/O points. There are three asynchronousscan cycles working together totransfer the remote I/O data between the PLC and the I/O modules: the EBC scan,the ERM scan and the PLC scan. These are described below.

During each PLC CPU scan, the ERM is allowed one access to the PLCs memory.The access can be a write to the PLC or a read from the PLC, but not both. There arefour types of data that are processed: discrete inputs, discrete outputs, analog inputsand analog outputs. The ERM can only process one of these four data types on anygiven scan. If all data types are used, it will take four PLC scans to completely updateall of the remote I/O points. The largest amount of data that the PLC can process in asingle request is 128 bytes. If any of the four I/O types exceeds 128 bytes of data, itwill take multiple scans to process that types data.

It is possible for the PLCs scan to be faster than the ERMs processing scan. This is

largely dependent on the size of the application program, as well as the type andnumber of remote I/O points. If there are I/O points that must be updated every PLCscan, it is recommended that those points be placed in the CPU base or localexpansion base.

1) PLC CPU Scan: executes program logic and scans local I/O. The PLC UserManual describes the PLC scan in detail.

2) ERM Scan: there are four I/O types that can be processed by the ERM: discreteinputs, discrete outputs, analog inputs and analog outputs. It takes a least one foreach of the four I/O types present to complete an ERM scan The typical ERM cycle isas follows:

PLC ScanN Read discrete output data from the PLCN+1 Read analog output data from the PLC

Write all of the output data to the EBCsCollect input data from the EBCs

N+2 Write discrete inputs to the PLCN+3 Write analog inputs to the PLC

3) Remote Slave Scan (EBC): constantly collects all discrete and analog input datafrom the input modules in the base. This keeps the most recent input data availablewhenever the ERM requests it. The EBC writes to the output modules as the data isreceived from the ERM.

In general, it will take four PLC scans to completely update the remote I/O. You canuse the ladder logic example on page B4 to get the ERM update statistics. This willprovide detailed information about the ERMs processing time.

Frequently Asked Questions

Q. Which protocols are supported by the ERM module?

A. A protocol is a set of rules that allows computers to connect with one anotherspecifying the format, timing, sequencing, and error checking for data packet

transmission. The ERM module supports Novell IPX and UDP/IP (UniversalDatagram Protocol/Internet Protocol). When configuring the ERM and EBCs., yourPC must support one of these protocols. However, the ERM and slaves can utilizetheir own protocol selection regardless of the protocols supported by your PC.

Q. Can I create multiple remote I/O networks by putting more than one ERM in a single PLC /WinPLC base?

A. Yes, for DirectLogic PLCs, but Think & Do WinPLC systems are limited to oneERM module with one slave per system to ensure reliable system performance. Ifmore than one EBC slave is desired in a Think & Do WinPLC system, please contactEntivitys technical support at 7342055000 or email [email protected]. Be sureto consult Chapter 2 for important installation information, and be sure not to exceed

the PLC power budget (see the module specifications in Appendix A and the PLCUser Manual). Also, it is very important to keep each ERM and its slave(s) isolatedfrom other ERMs and their slaves.

Q. What does it mean to set up the ERM module?

A. The ERM module must be configured using the Ethernet Remote MasterWorkbench to know how many slaves and I/O points there will be on the remote I/Onetwork. There are also other advanced ERM settings to configure.

Q. How much remote I/O can I have?

A. The ERM module supports up to 16 additional DL205 EBC bases, 16 TerminatorI/O EBC systems, 16 fully expanded DL405 EBC systems, Ethernet Interfaces for

AC Drives or any combination of the four. If a WinPLC is the system interface, theERM can only support one slave.

Q. Can I reserve slots in a base for future I/O expansion?

A. Yes, the Padding feature within the Slave Configuration window of the ERMWorkbench allows reserving addresses for future I/O modules at the end of each ofthe EBC slave systems (not between modules).

Q. Can I program or use an operator interface on the EBC slave when used with an ERM?

A. No, the serial port on the EBC slave is not supported at this time when used withan ERM module.

Q. Which LAN topology should I use?A. ERM modules are available for connecting to 10BaseT or 10BaseFL (fiberoptic) networks. The cable distances and environmental conditions often dictatewhich media type should be used. The most popular and flexible topologycurrently is 10BaseT, but 10BaseT is susceptible to electrical noise and is limitedto relatively short cable runs. On the other hand, it is very simple andinexpensive, and repeaters can be used to extend its cable length limitations.10BaseFL allows much longer cable runs with immunity to electrical noise. Thefiber optic cable and hubs are currently more expensive than those for 10BaseT.

ERM / Remote Slave Network Identifiers

This chapter describes the various network identifiers used by the ERM and its slavemodules. Each module on a network must be uniquely identified. There are three

indentifiers that can be used to make a module unique.The three module identifiers are:

Module ID

IP (Internet Protocol) Address (A slave can be used on the Internet, butI/O cycle times may be very high!)

Ethernet Address (MAC Address)

The first two are user-selectable. The third one is set at the factory. A Name may beassigned to a module, but the ERM cannot address a slave by its Name.

The identifiers are used to link the ERM module to its remote slaves The decision

about which type of identifier to use is an important one. Much of the decisiondepends on the protocol requirements of your particular application. Ease ofmaintenance and troubleshooting also must be considered before deciding whichtype to use.

ERM Workbench software utility must be used to configure the ERM and its slavemodules. If either Module ID (set by dip switch) or Ethernet Address is used fornetwork identification, then ERM Workbench is all that is needed to configure thenetwork modules. ERM Workbench is described in detail in Chapter 3.

NetEdit software utility will be needed in addition to the ERM Workbench if IPAddressing (UDP/IP) is necessary or if the Module ID is software set. If the H4EBCslave is used with analog I/O or the high speed counter, NetEdit will be required toconfigure the H4EBC. NetEdit is described in detail in Chapter 4.

ERM / SlaveConfigurationTools


18/81


Always set the ERM Module ID to 0. A slave Module ID can be set in one of two ways.You can assign the Slave Module ID:

using the DIP switches on the module (163). using the configuration tools in NetEdit that is included within the ERM

Workbench utility (165535).

Use the DIP switch if you want the ability to install or change slave modules withoutusing a PCto set the Module ID. Set the modules DIP switch, insert the module inthe base, and connect the network cable. Your Module ID is set on powerup, andyour module is ready to communicate on the network.

If you prefer to be able to set or change all Module IDs on your network from a singlePC, use the tools in NetEdit. In chapter 4, we step through the use of NetEdit and thenetwork identifier options.The Module ID equals the sumof the binary values of the slide switches set in the ONposition. For example, if you set slide switches 1, 2, and 3 to the ON position, theModule ID will be 14. This is found by adding 8+4+2=14. The maximum value you canset on the DIP switch is 32+16+8+4+2+1=63. This is achieved by setting switches 0through 5 to the ON position.

SafetyGuidelines


An IP Address can be assigned to the ERM module or its slaves if your networkrequires one. Normally, a network administrator will assign an IP Address to eachdevice on the network. Since it is recommended to use a separate dedicatednetwork for your ERM , you do not have to use the IP Address, unless you are usingthe UDP/IP protocol. Use the Module ID or Ethernet Address for each module whenusing the IPX protocol.

You can use NetEdit within the ERM Workbench utility to give the ERM or its slavemodules an IP Address. Each ERM and slave must have a unique IP Address.The module ships from the factory with an IP Address of 255.255.255.255. This isnot a usable IP Address for normal communications. It only serves as a defaultsetting which can be changed using NetEdit. The valid settings are 0 through 254.You do not have to change the default IP Address unless you are using IP Addressprotocol. The default setting does not cause conflicts with other networkcommunications.If you change the default IP Address for linking to other network devices, you mustchange all four 255 fields. If any field contains the number 255 andother fieldshave been changed, the module will notbe recognized on the network.

Valid IP Address: 192.168.100.002Example

No! 255.168.100.002

WARNING: There cannot be duplicate IP Addresses on your network. If you areusing the IP Address, all modules must have a unique number.

A unique Ethernet Address is assigned to each module at the factory and will not

change. It is printed on a label attached to each module. The Ethernet Address isrecognized by ERM Workbench and NetEdit. The Ethernet Address is a twelve digitnumber with no deliberate relationship to your network or functional areas of yourplant. It does not usually serve as a convenient and easily remembered identifier forthe module.

NOTE: The User Manual for Analog I/O Modules discusses scan times for updatinganalog I/O data for modules installed in local bases. Please be aware that the scantimes for updating are different for remote I/O modules installed in remotebases. The CPU scan is asynchronous with the remote scan by the mastermodule. Thus, an analog input module installed in a remote base, for example, maynot have its data updated by the CPU once every scan per channel as stated in theuser manual. The CPU scan may, in fact, cycle several times while the remote scanis taking place. Take this into account in applications where the timing is critical.

SafetyGuidelines


Most 10BaseT hubs or repeaters use a patch (straight-through) cable forconnecting the network devices (PLCs or PCs). For hub-to-hub connections acrossover type cable is commonly required. The figures on page 36 show pinassignments and insulation color codes for patch (straight-through) and crossovertype Ethernet cables.

The ERM has an eight-pin modular port that accepts RJ45 type connectors. UTP(Unshielded Twisted-Pair) cable is rated according to its data-carrying ability(bandwidth) and is given a category number. We strongly recommend using acategory 5 cable for all ERM connections.

Each module has two bayonet ST-style connectors. The ST-style connector uses aquick release coupling which requires a quarter turn to engage or disengage. Theconnectors provide mechanical and optical alignment of fibers.Each cable segment requires two strands of fiber: one to transmit data and one toreceive data. The ST-style connectors are used to connect the H2ERMF orH4ERMF module to another H2ERMF or H4ERMF module or a fiber optichub or repeater.

The H2ERMF and H4ERMF modules accept 62.5/125 multimode fiber optic(MMF) cable. The glass core diameter is 62.5 micrometers and the glass cladding is125 micrometers. The fiber optic cable is highly immune to noise and permitscommunications over much greater distances than 10BaseT.

42Configuring the ERM and Remote Ethernet Slaves with ERM Workbench

ERM Workbench Software

Ethernet Remote Master (ERM) Workbench is a software utility that must be used toconfigure the ERM and its remote Ethernet slaves. The ERM Workbench supportstwo methods of configuring the ERM I/O network. Both methods are explained later

in this chapter.The two configuration methods are:S ERM Workbench PLC Wizard simplifies the ERM I/O network

configuration procedure when a PLC is used as the CPU Interface.S ERM Workbench configures an ERM I/O network whether the CPU

Interface is a PLC or WinPLC, and allows access to all ERM I/O networkparameters.

NetEdit, a software utility within ERM Workbench, can be used to set the Ethernetmaster/slave Module ID, set an IP address if necessary or configure 405 EBCs withanalog I/O modules. Both ERM Workbench and NetEdit can be used to monitor theremote I/O network and to perform diagnostic and troubleshooting tasks.

ERM Workbench can run on Windows 98/ME/2000/XP or Windows NT. ERMWorkbench is included with this manual on 3.5 diskettes. The latest version of ERMWorkbench is available for download from Host Engineerings web site(www.hosteng.com). ERM Workbench consists of several files, all of which must belocated in the same directory. The installation process places the files in theC:\HAPTools directory (default). The files may be placed in another directory, butremember all of the ERM Workbench files must be placed within the same directory.

Place disk 1 of 2 in Drive Aor Drive B. Click on the Windows Start button and thenselect Run. Type in the path and filename (ex. A:\setup), or click on the Browsebutton to find the directory and filename (ex. if ERM Workbench was downloadedfrom web). A series of windows will step through the installation process for disks 1and 2. Fill in the necessary information as the installation wizard prompts through the

install. In the Setup Type window, select Typical setup. This setup type isrecommended for most users.

Installing ERMWorkbench


31/81


There are three methods to launch ERM Workbench.The two methods are:

S using the Windows Start menu Programs>AutomationDirect Tools>ERMWorkbench as shown below

S launching DirectSOFT32, then select PLC >Tools>ERM WorkbenchS

launching DirectSOFT32, then select Utilities>ERM Workbench

You may have already set up your PC with selected networking protocols forEthernet communications. If not, you will need to select the protocols now forcommunication with the Ethernet modules. We strongly recommend that youinclude the IPX protocol. For Windows 2000, go from My Computer on yourWindows desktop to Control Panel. Double click on Network and DialupConnections, then double click on the desired Network Device to see the installedProtocols. If IPX is not listed among the protocols already loaded, add it now byclicking on the Install button. For Windows XP, go from Start>Settings>Control

Panel. The steps are the same as Windows 2000 from this point.Add the TCP/IP protocol if it is necessary for your application. The TCP/IP selectionwill give you support for the UDP/IP protocol. Also, add the IPX protocol if it is notalready active.

NOTE: We strongly recommend you load IPX protocol on your PC for the connectionfrom your PC to the ethernet modules. Use UDP/IP in your application, if required,but also add IPX to your list of active protocols. Having IPX loaded on your PC givesyou a backup for troubleshooting communication problems.

Guidelines



A starting PLC V memory address must be specified for each of the four types of I/O.The ending address for each I/O type is determined by the amount of each I/O typeused by the slaves. The PLC Memory Map is divided into 4 separate tables.1) Discrete Inputs: This is where the ERM will Write all of the slaves Discrete Inputdata.2) Discrete Outputs: The ERM will Read this from the PLC and Write it to the slavesDiscrete Outputs.3) Analog Inputs: This is where the ERM will Write all of the slaves Analog Inputdata.4) Analog Outputs: The ERM will Read this from the PLC and Write it to the slavesAnalog Outputs.

It is recommended to use the V404xx (Xs)for Discrete inputs and V405xx (Ys) forDiscrete Outputs that are beyond the local/expansion base I/O that exists. Thedefault addresses are V40414 (X300) and V40514 (Y300). Note that the StartingPLC address and the Starting Discrete I/O Address are not the same. The firsttwo words of V memory in the Discrete Input table is used for ERM/slave statusinformation, and the first word of V memory in the Discrete Output table is for

Disable Slave Command bits. Adjust these address as needed, but do not mapover local I/O used and be sure the PLC supports the alternate addresses selected.

Clicking on the ERM Configuration Advance button displays the following window.

Standby Cycle Timeis the time the ERM will wait before trying to communicate with aslave that had a communication error. Enabling this feature will help overall I/Othroughput when one slave errors in a multislave network. If the Standby CycleTime is disabled, the ERM will try to communicate with the slave in error every I/Ocycle. If enabled, the ERM will try to communicate with the slave in error at the giventime interval.PLC Scan Timeoutis the time for the ERM to wait on the PLC when the PLC is notresponding due to long PLC scan times. It is recommended to keep it at the default of100ms or twice the maximum PLC scan time, whichever is greater.

Unsupported Slave Cycle Time is the time the ERM will wait before trying tocommunicate with a slave that cannot be supported by the ERM. An unsupportedslave may have an I/O configuration that does not match the ERMs or may haveobsolete firmware. If disabled, the ERM will not try to communicate with theunsupported slave again until ERM power is cycled. If enabled, the ERM will checkslave support at the given time interval. If the slave is then supported, the slave will

be included in the ERMs I/O cycle.Advanced ERM Network Settingsare used to configure the ERMs UDP/IP subnetmask for IP address handling. Consult your network administrator if needed.

The right column displays the Slave Configurationof the slave that is selected inthe ERMs Slave List.E. The Upgrade Firmware Utilitycan be used to upgrade the firmware in the ERM orslave modules if necessary.F. NetEditcan be used to assign IP Addresses to the remote I/O network modules ifrequired. NetEdit is also required if Module ID is to be software set or if the 405 EBCis used with analog I/O modules. Normally, a network administrator will assign an IPAddress to each module on the network. Since it is recommended to use a dedicatedremote I/O network, it is not necessary to assign IP Address unless the UDP/IPprotocol must be used. Refer to Chapter 4 Using NetEdit for more information.

Configure the Slaves

Remote slave parameters (protocol, address mode, timeout, etc.) are setindividually for each slave. To configure a slave, select a specific slave in the ERMsSlave List and either double click on a specific slave in the ERMs slave List in theSelect Salves window or click on the Configure button.

The values may need to be raised in applicationswhere IP addressing and routers are used or if a dedicated remote I/O network is notused.D. Enablingthe Slaves Watchdog Timeoutruns in the slave and allows the slave toturn off all outputs when the slave no longer receives any I/O requests from the ERMmodule. Any outputs that were on at the time of the error will turn off after thespecified time elapses. Set the ERM Pet Frequencyruns in the ERM to reset thewatchdog timer in the slave to avoid any nuisance timeouts due to main CPUinconsistent logic times or ERM I/O cycle times.Disablingthe the slaves WatchDog timer will cause all of the outputs to remain intheir last state indefinitely (hold) when the slave no longer receives any I/O requests.E. Reserve PLC Addresses for Expansionallows future I/O modules to be added orexisting modules to be removed from a slave without affecting the PLC addresses ofthe other slaves on the network. Pad the discrete inputs and outputs using bytes (8points per byte) and the analog I/O using words (2 bytes). Padding can only be donefor I/O at the end of a slave I/O base, not between two I/O modules on the slave.F. The Make Offline Feature may be useful for users or OEMs that requireduplicating a system several times. For example, a system may consist of 3 EBCs.An offline ERM configuration allows each additional ERM to be configured withoutactually connecting its slaves at configuration time. Once the initial ERM system isconfigured, its ERM Workbench configuration file can be used to create anotherconfiguration file with different slave addresses.Checking the Make Offlinecheckbox allows slave addresses to be manually set thatshould be used by the ERM. This does not change the address in the slave, butchanges the ERM configuration to address a different slave without connecting it onthe network when configuring the ERM.

Once the CPU Interface and Slaves have been selected and configured, the networkI/O modules and I/O points will be listed by slave and slot number as shown on thenext page (A.). The next step will be to write the configuration to the ERM module.

F. Detailed ERM Status provides ERM I/OCycle Times. This is the time required for

the ERM module to update all of its I/Opoints. Remember the ERM and the PLCCPU operate asynchronously from oneanother. The PLC CPU scan will be fasterthan the ERM I/O Cycle Time. Thus, theremote I/O points will not be updated everyPLC CPU scan.

Analog I/O Data Registers

Analog input data is mapped channel by channel in decimal format (binary) intoconsecutive V memory locations when used in an EBC base. Each individual analogI/O channel has its own 16bit V memory location. For example, an 8 channel analoginput module with starting PLC V memory address of V2000 would map the 8channels of analog data into V2000 V2007, respectively. Analog output dataneeds to be in decimal format (binary). Be sure to convert any BCD values todecimal before sending the data to the analog output registers.Refer to theAnalogI/O Manuals for conversion examples. Terminator analog I/O modules consumetwo (Double) words per channel (32bits). See Appendix E for configuringTerminator I/O analog output module control byte.The EBC slave modules automatically maps the analog I/O data in/out of V memory,thus multiplexing ladder logic or pointer method is not necessary.

Note that the 205/405analog I/O channels arelisted as 16bit Binaryconsecutive data registers

(1 word) and the Terminatoranalog I/O channels arelisted as 32bit Binarynonconsecutive dataregisters (Double Word).

NetEdit is a software utility which can be used to set network identifiers (Module ID,or IP Address) for the network master and slave modules. NetEdit is accessed fromthe ERM Workbench Select Slaves window or the View>NetEdit Window. NetEdit

can also be used for diagnostic and troubleshooting tasks. This section stepsthrough the individual segments of the NetEdit utility and the function of each.

In the upper left corner of the NetEdit window, you will find a box labeled Protocol. Inthe box, there are two choices: IPX and UDP/IP. The ERM and its slave modulesunderstand IPX andUDP/IP protocols. Both protocols are permanently residentinthe firmware of the modules.

When you click on one of these radio buttons, you are selecting the protocol youwant your PC to use to allow NetEdit to communicate with the master or slavemodules. You are not telling the module which protocol to use. IPX is a Novellstandard in widespread use, and UDP/IP is a popular protocol supported by theTCP/IP suite of protocols in your PC.

The figure to the right shows theProtocol selection box in the upper leftcorner of the NetEdit window. Thechoice you make here tells your PCwhich protocol to use to link NetEdit tothe master or slave modules. You arenot selecting which protocol theremote I/O network will use.

You may have already set up your PC with selected networking protocols forEthernet communications. If not, you will need to select the protocols now forcommunication with the ECOM module. We strongly recommend that you includethe IPX protocol. The description below applies to Windows 2000 (Windows 98/NThave slightly different steps). If you are not familiar with this procedure, you mayneed to have your Network Administrator perform this task.

For Windows 2000, go from My Computer on your Windows desktop to ControlPanel. Double click on Network and Dialup Connections, then double click on thedesired Network Device to see the installed Protocols. If IPX is not listed among theprotocols already loaded, add it now by clicking on the Install button. For WindowsXP, go from Start>Settings>Control Panel. The steps are the same as Windows2000 from this point.Add the TCP/IP protocol if it is necessary for your application. Choose the TCP/IPselection to get UDP/IP support. Also add the IPX protocol if it is not already active.

NOTE: We strongly recommend you load IPX protocol on your PC and use it for your

module links. Use UDP/IP in your application, if required, but also add IPX to your listof active protocols. Having IPX loaded on your PC gives you a backup fortroubleshooting communication problems.

The Module box lists the EthernetAddressesof the modules currently onthe remote I/O network.
