Communication Types - Siemens ET 200SP Operating Instructions Manual

Configuration and operation
4.5 Telecontrol communication (CP 1542SP-1 IRC)
4.5.2

Communication types

In this parameter group, you enable the communication types you want to use for the
particular CP..
To minimize the risk of unauthorized access to the station via Ethernet, you need to enable
the communications services that the CP will execute individually.
The Open User Communication does not exist in the parameter group because these
communications services are not configured but programmed using program blocks.
The parameter group does not exist for the CP 1542SP-1, since the communications
services supported by this CP are always enabled.
