Tip: Creating your own bulk edit formats

While many people are familiar with using bulk editing to quickly configure modules or I/O using standard formats,

most people dont realize how easy it is to utilize and create custom format files.

The standard format files are very good for many things, but are not useful for configuring parameters that are not

included in the standard format files or modules that are

very custom.

Bulk Edit

2012

USERS EXCHANGE

To begin creating your own format files in DeltaV Explorer;

click File | Format Specification | New (or edit if you want to edit one you

have previously created)

Page 6

Bulk Edit

2012

USERS EXCHANGE

In the first dialog box, you will need to browse to a location where you

want to create the format file. By default it will be the BulkEdit folder and

type in the name of your format with the .fmt extension, then click Next.

Page 7

Bulk Edit

2012

USERS EXCHANGE

In the next dialog box you first select the object type, such as Module if the format is to be used for a module.

Then you browse for a subtype, if you were creating a format for a class based module or modules of a particular type, simply browse to

an example of this module in the configuration database.

At this point you can select parameters in the left box, which lists parameters in the module, and send them to the box on the right, which

will be the parameters in the format file.

NOTE: You may have to click Filter Parameters and check additional

categories to get some parameters to show up in the left box so that you

can add them.

After selecting all parameters click Next and in the following dialog box set the order that parameters should appear in the format file. This is

not required but can help organize parameters for ease later.

After that there is a dialog box for selecting whether certain parameters must be included, typically this can be left as is and simply

click finish.

Now you can use this new format file to bulk edit many things that are not possible using standard format files.

To edit a format file, simple choose Edit rather than New when starting the process and you can edit an existing format file if you realize you

need to add or remove anything.

Tip: CHARM I/O Configuration V11, S-series

Not only can CHARM I/O be moved physically around easily by changing CHARM modules and assigning to

different controllers, but the configuration can also be

easily moved around and modified in ways that are not

possible with other types of I/O.

Methods such as bulk editing work, but there are some things to know when doing so.

CHARMS

2012

USERS EXCHANGE

CHARMs channels can be dragged from one location to another.

Simply click on CHARM and drag it to an undefined location and drop it.

All properties will be applied to new channel and old channel will be undefined.

CHARM channels can be copied.

All that will be left to configure is the Device Tag

Either right click and copy and then paste, or Ctrl-C and Ctrl-V work

Deleting channels is an easy way to set them back to undefined in one step.

Copy, delete and assigning work on multiple channels.

In case of copy you must remember to select the appropriate number of undefined channels to paste to.

USERS EXCHANGE

Not all things you might expect are in channel properties tab.

o For example, to select number of wires for an RTD you must drill

down one level and change NUM_WIRES parameter

o At this level are other things such as COMPENSATION and

FILTER parameters, as well as calibration parameters for user

defined RTD type.

Bulk editing

o The default format files for bulk editing CHARMS do not go beyond

what you can do on properties tab.

o You will need to create custom format to edit information such as

the parameters listed above.

It is recommended to Ignore the HART_ERRORS at the

I/O level to reduce nuisance

alarms.

Tip: HART Configuration

CAUTION: A HART transmitter can be re-ranged from DeltaV.

When configuring the AI block using HART_FIELD_VAL set the EU to no

units, null or - to avoid this.

For DIRECT set the OUT_SCALE and for INDIRECT set the XD_SCALE.

Tip: Using zPicture to debug

zPicture

2012

USERS EXCHANGE

Page 19

zPicture resides in the Graphics-iFix\Pic\Standard directory. It can not be accessed from the Open Main Picture icon/dropdown on the toolbar

(if it exists). It can be opened from the File Open on the menu bar. The menu bar may not be visible if it is disabled in the Environment

Protection tab of User Preferences.

USERS EXCHANGE

Page 20

With zPicture open, you may select frsVariables or Picture/Globals to be displayed. There is an area to type in a search term to limit the

results.

zPicture displays 5 tabs (pages) of variable data. If the search returns more that can be displayed on the 5 pages, you will see a message in

the lower right corner that indicates Some variables are not visible.

This display may help you identify the values assigned to variables at run time that are otherwise difficult to find.

Tip: Class Module Parameter Rename

When renaming a parameter in a class module, be aware of this additional step that is required.

Using the following simple AI module as an example. The class module is instantiated and appears as follows:

Page 22

When the parameters are renamed, notice what has happened:


2012

USERS EXCHANGE

Page 23

In order to resolve the Parameter Shortcut to the Parameter Path Name,

you must go to the Parameters tab of

the module Configuration, select the

parameter and press Default Name (at

the class level).

This can be very confusing because if this step is not taken, the parameter will

have the new name in the module, but

you will see the original parameter name

in DeltaV Explorer.

Also, when browsing for a parameter, the Parameter Name will be displayed

NOT the Parameter Shortcut.

USERS EXCHANGE Rolling Average RPM

Scenario:

Customer needed to control the amount of product being applied. The only

information available was a proximity switch that makes every revolution of a

gear on the supply motor. The customer knows how much product is supplied

for a revolution. The problem is to use this information as a process control

variable in a PID loop.

Page 27

Solution:

The following slides show a module that was created to count the number of

high signals from a proximity switch. The values were fed into an array.

The values are then totaled and then divided by the number of entries to

provide a rolling average RPM. This is a first in first out array. The number of

samples is adjustable to increase accuracy.

2012


Page 28

Counts the number of prox makes in a minute

Triggers RPM to be added to array

Array

Number of samples adjustable

Calculation does not start until motor is running

2012


This logic calculates the RPMs of a feeder by counting the number of times a proximity switch makes. The number of revolutions

are brought in and assigned to the variable 'Revolution'.

Every 60sec the trigger variable goes true which moves the next RPM count into the array. The values in the array are added

together and the total is divided by the number of entries which can be adjusted with the parameter 'No-samples'. This gives a

rolling RPM average.

Page 29

(* Define variables *)

Revolutions := 'IN1';

Trigger := 'IN2';

NoTestReq := 'IN3';

(* Determine the number entries *)

If Trigger=True or FirstScan = False then

FirstScan := true;

NoTestUsed := NoTestUsed + 1;

If NoTestUsed > NoTestReq then

NoTestUsed := NoTestReq;

end_if;

(*Clear variables *)

Total := 0;

i := NoTestUsed - 1;

(* First shift all of the array entries down by one then total their values.*)

WHILE (I >= 1) DO

'^/DATA_ARRAY'[I+1][1]:= '^/DATA_ARRAY'[I][1];

Total := Total + '^/DATA_ARRAY'[I+1][1];

I := I - 1;

END_WHILE;

(*Add the latest RPM entry*)

'^/DATA_ARRAY'[I][1] := Revolutions;

Total := Total + Revolutions;

end_if;

(* ASSIGN AVERAGE TO OUTPUT *)

IF 'IN2' THEN

'OUT1' := Total / NoTestUsed;

ENDIF;

'OUT2' := Total;

'OUT3' := NoTestUsed

Tip: Limit Access to Sessions

Limiting the available sessions on a

node basis.

Example of usage could be to limit

area access to specific sessions.

To setup, go to properties on the

specific session in DeltaV Explorer:

2012

USERS EXCHANGE

Page 32

Then from the Remote Client Session Properties, select the Reserved for

Node List. Then add the specific node from Thin-Manager that the session

will show up on. All sessions must be assigned, otherwise they will

show up in the drop down menu.

Tip: Limit Access

How to use THISUSER parameter to limit access.

Parameter Security can be used to limit access to

individual parameters, but there are cases where

you may want to block access to a group of

parameters.

This can be done with a transparent rectangle

placed on top of the area to be restricted. The

visibility of the rectangle is then controlled with the

THISUSER/USER_CAN parameter.

In this example, the visibility Data Source is

DVSYS.THISUSER/USER_CAN.B_CV[AREA_A][

TUNING] = 0. If the logged in user does not have

the TUNING key, the transparent rectangle will be

visible and the user cannot click through it.

Tip: Console Session 0 for Remote Access

With DeltaV v11.3, MS Server 2008 Eliminated the FREE console session that was used by many for remote access to the

ProPlus or Application Workstations

Solutions: Use of iDRAC card in Dell Server Ethernet KVMs VNC Software

Remote Access

2012

USERS EXCHANGE


iDRAC in Dell Server

iDRAC6 Express is built into R710 servers but only provides diagnostic type information and does not provide remote console, that requires iDRAC6

Enterprise which is an additional card.

One component of the card which is installed is an Ethernet port which can be connected to plant LAN, business network or a dedicated management

network.

Server can then be accessed across the network through the DRAC using a web browser, and then initiation a remote console session.

Added benefits are the ability to connect to and power on the machine remotely, along with accessing all the diagnostic information usually

available through Dells Open Manage software.

Not Standard with Dell Servers from Emerson but can be added.

Ethernet KVM switch

Serve both as a local cabinet KVM as well as allowing access across network when connected to business network.

Since the KVM is connected locally to the server, it is just like being there in front of the server, even if you are across the plant accessing it from

another machine.

Many companies already have these types of KVMs in place, if so there is no need for an alternative solution and if adding a new cabinet or new KVM

to existing cabinet, it makes sense to install one of these rather than a

conventional KVM switch.

Cost per server can vary greatly depending on particular KVM switch, number of ports and the number of interface modules (one required for

each server).

VNC (Virtual Network Computing) Software

VNC is a desktop sharing system, that allows one computer to control another.

It requires that a VNC server is installed on the machine to be controlled and that a VNC client is installed on machine that will be used for access

and to control the target machine.

There are many variants using different protocols and levels of security.

This may be the best solution if it is preferable not to add any additional hardware either in the cabinet or to a server, but has the disadvantage of

requiring software on both server and client.

Do not build more that 3 simultaneous Dynamic references in a phase action at a time.

o Dynamic reference building is very resource intensive while path

is being resolved.

o Can bring the Controller Free time to almost Zero causing

other Batches to go into PLM watchdog failure.

Example, if you need to do 12 or more dynamic references then do three per action with each of the four actions Delayed based on the previous action

being complete or put in four different phase steps.

Caution when using cross-controller dynamic references. It is possible to bring a controller free-time to ZERO when using a dynamic reference

in a different controller, if the controller fails to communicate.

Tip: Batch Executive Restart

When a BatchExec fails and needs to be rebooted, all the current running batches go to a Lost state upon BatchExec restart. To get them back, the following must be done:

a. Select a batch and select Recover. b. The batch should return to the Hold state. c. The batch must be set to Auto mode. d. Acknowledge any existing failures.

e. Restart the batch.

Note: Occasionally, a batch will go to a Recover-Fail state instead of Hold. When this happens, another reboot of the BatchExec will result in a

successfully recovered batch.

Tip: Batch Configuration Search

When searching a large FHX file (i.e. for an entire unit or system) for parameter usage, it can be difficult to determine what phase you are

currently searching. To get the phase name, do the following:

a. Search DOWN for the parameter in question.

b. Search UP for the term function_block. c. Grab the Hex ID of the function block (e.g. _4CC0705B_05F8A26D_).

d. Search DOWN for the Hex ID you grabbed.

e. Search UP for the term batch_equipment. f. The result will look like: BATCH_EQUIPMENT_PHASE_CLASS NAME

=phase_name which tells you what phase the param is in.

Tip: Adding Redundant Controller On-Line

You can connect a second controller to an existing controller's carrier to

introduce redundant control without interrupting your process.

The system automatically commissions a standby controller when installed.

It is not necessary to remove or decommission the active controller.

The active controller continues to operate without interruption.

The system automatically assigns the standby with an address and downloads the standby controller with the latest download and

with any online changes made to the active controller.

Redundant Controller

2012

USERS EXCHANGE

Page 54

To install a standby controller follow these steps:

Using the DeltaV Explorer, assign an appropriate redundant controller license to the controller node that you want to make redundant.

Install a second 2-wide carrier to the left of the current 2-wide carrier. Insert the appropriate Power Supply in the left slot of the 2-wide carrier plug in the power cord.

Connect an MD, or higher version controller to the carrier. The version of the controller you connect must match the existing controller's version.

DeltaV Explorer displays a redundant controller icon in place of the simplex icon.

In the DeltaV Explorer, Download Setup Data to enable redundancy for the pair

Caution: Do not install a second 2-wide carrier with the power supply and

controller already installed. Doing so will result in a loss of configuration

data for the active controller.
