About Series 90 TCP/IP Communications

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



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.
