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
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
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.
