Hello fredy; The front RS-232 port of the Siprotec relays is only for DIGSI software connection, to parametrize the relay. You will need that software to set ithe relay up, configure the communication board you will eventually install (in the back of the relay), connect internally the digital input/output signals to relay functions... First you will need to determine what communication protocol you will use, and connect to your PLC: Profibus-DP, Modbus RTU, IEC 61850... Then you will need to check how your PLC can be setup for this communication protocol (most S7 PLCs can be natively Profibus-DP masters, but for Modbus and other protocols you might need to purchase hardware/softwarem supplements). Once that is achieved, you need to look at the communicationsfiles provided for each relay type: each porotocol has different setups that must be studied and understood before the link will work. Here is the link to the Siprotec family of relays: http://w3.siemens.com/smartgrid/global/en/products-systems-solutions/protection/pages/overview.aspx Here is the link to documentation for the (Siprotec 4) 7SJ62 (open the Downlaods tab, then the Communication Protocols link): So, start by selecting the protocol you need, we will be able to help you further when the initial steps are done. Or search the forum for threads on the Siprotec protocols (try "7SJ62 Profibus-DP" in the search box at the right, for example). Finally, this link will take you to the DIGSI 4 webpage (open the Downloads tab, click on the manuals link, look especially at the Siprotec 4 and DIGSI 4 system manuals): Hope this helps, Daniel Chartier |
