TeSys U
controler
This section describes three references of TeSys_U control unit (Standard, Advanced, Multi-function), connected
between STB main rack and STB extension rack.
An Ethernet IO scanning service is used to periodically exchange data between the PLC and the motor starter.
For TeSys_U behind an Advantys STB island, the STB island I/O mapping is used.
The table below details the interface between the starter and the DFB into PLC application.
