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
– PM856A and PM860A - Now 16 Mbyte total RAM
