This document contains information about one or more ABB products and may include a
description of or a reference to one or more standards that may be generally relevant to
the ABB products. The presence of any such description of a standard or reference to a
standard is not a representation that all of the ABB products referenced in this document
support all of the features of the described or referenced standard. In order to determine
the specific features supported by a particular ABB product, the reader should consult the
product specifications for the particular ABB product.
This Product Guide is intended for sales representatives to provide information on
Compact Control Builder AC 800M and OPC Server for AC 800M.
Engineering Environment
• Diagram Editor with Function Diagram - Diagram is a new graphical language
that graphically interconnects functions, function blocks, control modules and
embedded ST and SFC code blocks on the same page.
• Search and Navigation - Communication variable references from other
projects within the same system do now appear as references, if the projects are
downloaded.
• Task Analysis Tool - The task analysis tool in Control Builder has been made
more easy to use. The meaning of the different messages is now more precise.
Time stamps have been added to the warning and error messages in the
summery view of the Task Analysis tool, this makes it easier to relate between
the messages and the graph.
• Display of Unit Specific System Alarm and Event Generation - There is a new
menu entry in Control Builder on hardware types called Unit Specific System
Alarm and Events. It brings up a new user interface that shows what system
alarms and events a unit can generate. The information is shown in Control
Builder rather than being printed in a user manual.
• Heap Utilization Dialog Available in Online Mode - The controller heap
utilization dialog in Control Builder is now available also in online mode.
• Additional Caution Dialog at Download with Init Restart - An additional
caution dialog is shown before download of changes in case the user or the
system suggested an init restart (i.e. loss of all cold retained values).
• Compiler Warning in case Data Type used for IAC has been changed
If the user changes a structured data type used for communication variables,
then the receiving controller will get ISP until both server and client have been
downloaded to. With this new version, the user gets to know in advance in case
a download of changes includes changed data types that will cause ISP on any
communication variable.
Control and I/O
• CI873 EtherNet/IP
The CI873 EtherNet/IP has been improved. It now supports master redundancy
by using two CI873s. The redundancy does not require the slaves to have the
EtherNet/IP redundancy connection method implemented. There is now also
support for native EtherNet/IP devices. CI873 supports logical segment Class 1
connection for reading and writing data to EtherNet/IP devices, and it
originates Class1 for tag reading and Class 3 for tag writing to Allen Bradley
Logix 5000 series PLCs.
• CI868 Enhancements
– IEC 61850 Wizard Tool improvements
– IEC 61850 MMS Client functionality for CI868 Module
• Self-defined UDP and TCP Communication
The new UDPCommLib and TCPCommLib contains function block types that
are used for self-defined UDP and TCP communication. These function blocks
are used when the controller needs to communicate with external equipment.
The used protocol is UDP and TCP, running on Ethernet. The function is
similar to the already existing self-defined serial communication, but on
Ethernet. It uses the inbuilt CN1 and CN2 on the PM8xx CPU. Redundancy is
handled by RNRP.
• Support for DI818, DO818, DI828, DO828
This version supports four new S800 I/O modules on modulebus and
PROFIBUS via CI801/CI840.
– DI818 - 32 channel digital input for 24VDC
– DO818 - 32 channel digital output for 24VDC
– DI828 - 16 channel digital input for High Voltage AC/DC
– DO828 -16 channel relay output for High Voltage AC/DC
• More memory with PM851A, PM856A, PM860A - These renewed CPUs have
with this version more available memory:
– PM851A - Now 12 Mbyte total RAM
