ACN CS controllerEmbedded industrial controller

ACN CS is a high performance multifunc-tion controller designed for embedded and standalone applications. ACN CS is used for process controls, connectivity, fast machine controls and advanced controls like fuzzy and multivariable controls.

ACN CS can be used in combination with ACN RT, ACN C20, ACN SR1 and Metso DNA VME controllers.

Industrial demands• Fast control cycles, as low as 20 ms• No moving parts (no fan nor hard disk)• IP20 enclosure protection• One-to-one redundancy capability

ACN CS

• Dual 100 Mbit/s Ethernet connections for commu-nication with other nodes

• Standard serial port links for communication with third party devices

• Removable CompactFlash.

Mounting ACN CSACN CS is installed either vertically on a mounting plate with screws, or on a shelf mounted on a stan-dard 19” rack.

InterfacesThe interfaces available in ACN CS are:

Three Ethernet ports on the CPU board that can be used for the following purposes: • Redundant Metso DNA Ethernet network

ACN CS has two 10/100Base-T Ethernet ports used for redundant Metso DNA Ethernet network. Metso DNA Ethernet network is based on switched Ethernet technology. Ring topology is recommended, star topology is also possible.ACN CS has one Ethernet interface active at a time. In case of failure, the reserve Ethernet inter-face immediately comes online.On the Ethernet network level, the changeover to the reserve switch takes 30 ms with the recom-mended ring topology and 1...2 seconds with the star topology.

• Interface with Metso DNA I/O field busesBy default, there is one 10/100Base-T port avail-able for Metso DNA I/O field buses. The interface with ACN I/O uses an Ethernet field bus and inter-face to rack I/O uses EFC connection unit.Two PCI slots can be used for additional Metso DNA I/O field bus interfaces.

• High Speed Ethernet (HSE) Foundation Fieldbus interfaceHigh Speed Ethernet uses a standard 10/100Base-T Ethernet port to HSE Linking Device(s), which has up to four H1 buses connected per Linking Device.

Two PCI card slots:Two PCI slots can be used for additional Metso DNA I/O interfaces, Ethernet interfaces to external systems, or for field bus interfaces like PROFIBUS DP and Foundation Fieldbus. ACN CS can have different I/O and field bus interfaces combined in the same node.• PROFIBUS DP Interface

PCI card slots are used for PROFIBUS DP inter-faces. The PROFIBUS DP card is a one- or a two-channel card.

• Serial interfacesACN CS has one RS-232 port available by default. PCI slots can be used for additional serial interfaces. The serial interface card is either an 8-channel RS-232 or a two-channel isolated RS-485/RS-422. Multiple serial interface protocols are supported.

• Ethernet interfaces:Interfaces to external systems using e.g. Modbus/TCP protocol.

RedundancyACN CS supports redundant Metso DNA Ethernet networks, redundant controllers (one-to-one redundancy), redundant I/O field buses for ACN I/O and rack I/O, plus redundant PROFIBUS DB field buses.

EngineeringThe engineering library of the ACN CS controller provides function blocks for controls at all levels, including basic process control, advanced quality, drives, and optimization controls. Fuzzy, MPC, and Java function blocks are available as a standard.Metso DNA Engineering - Function Block CAD tool is used for designing function block diagrams for process control loops, sequences, and interface applications.Function block diagrams are saved in a common database located on the Engineering Server. At the same time, a function block diagram is a graphical document of an application, which is loaded in the runtime environment. This ensures that the docu-mentation is always up-to-date.

Capacity• The typical number of I/Os connected to ACN CS

is less than 2000. The amount depends on the control cycles.

• Control cycles from 20 ms to 64 s, typically 400 ms.

• 1-3 Metso DNA I/O field buses, 1-4 PROFIBUS DP buses, 1 FF HSE bus, max. 5 field buses in total.
