SVC Siems

Coupling between the two  SIMATIC TDC systems is realized with the ipConv protocol converter.
The protocol converter and the control station communicate via IEC 60870-5-101. The proprietary Simatic TDC protocol is used for the communication towards the SIMATIC TDC system.

An ISDN router is accessed via a dial-up telephone line for remote maintenance. An optical wave guide (LWL) is used to bridge the 300 m transfer distance between the telephone connection and the protocol converter. The physical link to the protocol converter is realized with a media converter, which converts from optical signalling to Ethernet.
