Intersystem Communication
The Ethernet Intersystem Communications symbol (Ethernet ISC) allows two control
systems to exchange information over Ethernet. The ISC symbol takes its digital,
analog and serial inputs and converts them into packets for transmission on the
Ethernet network. At the destination control system, a matching ISC symbol receives
the packets and drives its outputs to the corresponding values. In this way, the inputs
of one symbol drive the outputs of the other symbol, and vice versa.
As with all other Ethernet devices, each Ethernet ISC symbol must have an entry in
the IP Table of each control system. Here the IP IDs of both Ethernet ISC symbols
must be the same. In addition, each symbol must be assigned the IP address or fully-
qualified domain name of the
target
control system. That is, in System A, an Ethernet
ISC symbol with IP ID 08 would be assigned the IP address or FQDN of System B.
The Ethernet ISC symbol in System B would likewise have IP ID 08, and be assigned
the IP address or FQDN of System A.
Note that there can be as many Ethernet ISC symbols in a control system as there are
available IP IDs (maximum of 251), and thus many communication channels can be
established between control systems.
The Ethernet ISC symbol cannot be used for intersystem communication between an
X-Series control system and a DHCP-enabled 2-Series control system.
