The Series 90 TCP/IP Communications enabler supports TCP/IP communication over Ethernet to Series 90-70 and 90-30 programmable controllers. This device communication enabler employs the Series 90 Host Communication Toolkit (HCT) as its underlying communication layer.
In addition, the Series 90 TCP/IP Redundancy Communications enabler supports various combinations of PLC and cabling redundancy.
This enabler supports the following CIMPLICITY features:
Polled reads at user defined
rates
Poll after setpoint
Triggered reads
Unsolicited data
Analog deadband
Alarm on communications
failure
Server Redundancy
configurations
This enabler supports the following data types:
Signed 8, 16, and 32 bit
integers
Unsigned 8, 16, and 32 bit
integers
Floating point
Text
Arrays
Important: The Ethernet
Global Data (EGD) Service does not work on Vista and Windows 2008.
Therefore EGD data collection will not work through the
legacy Series 90 Ethernet under Vista and Windows 2008.
