• Custom protocol development tools to meet the communication requirements of non-standard legacy equipment

AC 800M Communication interfacesCI865

The CI865 module is the AC 800M system’s communication interface for Satt ControlNet and bridges different bus standards used on AC 800M and Satt ControlNet. The CI865 module makes it possible to use older Satt I/O system (Rack I/O and Series 200 I/O) with the AC 800M controller platform, but it cannot be used as a general ControlNet interface. CI865 cannot be used in a High Integrity controller.

AC 800M Communication interfacesCI867A

MODBUS TCP is an open industry standard widely spread due to its ease of use. It is a request-response protocol and offers services specified by function codes.

MODBUS TCP combines the MODBUS RTU with standard Ethernet and the universal networking standard TCP. It is an application-layer messaging protocol, positioned at level 7 of the OSI model. The CI867A/TP867 is used for connection between an AC 800M controller and external Ethernet devices using Modbus TCP protocol.

The CI867 expansion unit contains the CEX-Bus logic, a communication unit, and a DC/DC converter that supplies appropriate voltages from the +24 V supply via the CEX-Bus. The Ethernet cable must be connected to the main network through an Ethernet switch.

The CI867A only uses one Ethernet port (100 Mbit/s) compared with the earlier CI867, where two Ethernet ports could be used (100 Mbit/s and 10 Mbit/s). The CI867A module will only work with System 800xA 6.0.3.3, 6.1.1, and subsequent versions.

AC 800M Communication interfacesCI868A

The CI868A can be used to connect an AC 800M controller to external Ethernet devices using IEC 61850 – Edition 2 standard. Since this is a standard for Substation Automation, this allows the combination of Process Automation and Electrical Control in the same controller.

The TP868 Baseplate has two RJ45 Ethernet connectors, where CH1 connector can use 10Mbps or 100Mbps (Mega bits/sec.).The baseplate has a code lock that prevents the installation of an incorrect type of unit onto the TP867 Baseplate.

The CI868 expansion unit contains the CEX-Bus logic, a communication unit and a DC/DC converter that supplies appropriate voltages from the +24 V supply via the CEX-Bus. The Ethernet cable must be connected to the main network through an Ethernet switch.

The CI868A module will only work with System 800xA 6.0.3.3, 6.1.1 and subsequent versions

AC 800M Communication interfacesCI869

The CI869 is an AC 800M communication interface that connects to the AF 100 field bus through the twisted pair (TWP). The CI869 expansion unit contains the CEX-Bus logic, a communication unit, and a DC/DC converter that supplies the required voltage from +24 V supply through the CEX-Bus. The CI869 can be configured for both redundant cables and redundant communication interfaces.

The CI869 communication interface attached to the AC 800M controller provides connectivity to other AC 800M, AC 160 or a connectivity server over AF 100. An AC 800M controller with the communication interface CI869 behaves as an AF 100 station, receiving data from other AF 100 stations/devices. The CI869 has integrated twisted pair modems. CI869 can also be used in an AC 800M High Integrity system
