Hello Mohsen John; And welcome to the A&D forum. Even though the Siprotec protection relays are developped and marketed by the SiemensEnergy division (different from our Industrial Automation and Drives division), some of us have had occasion to work with them and can try to help you out. Have a look at this extract from a Siprotec 7SJ22 protection relay brochure, it discusses communication ports and the available protocols you can use: SIPROTEC 4 7SJ62 Multifunction Protection Relay - Siemens Serial front interface There is a serial RS232 interface on the front of all the units. All of the unit’s functions can be set on a PC by means of the DIGSI 4 protection operation program.Commissioning tools and fault analysis are also built into the program and are available through this interface. Rear-mounted interfaces) A number of communication modules suitable for various applications can be fitted in the rear of the flush-mounting housing.In the flush-mounting housing, the modules can be easily replaced by the user.The interface modules support the following applications: … System interface protocols (retrofittable) IEC 60870-5-103 protocol The IEC 60870-5-103 protocol is an international standard for the transmission of protective data and fault recordings. All messages from the unit and also control commands can be transferred by means of published, Siemens-specific extensions to the protocol. See also the attached order number selection for the rear port (Port B) of the relay, taken from the same document, page 5/112. So your attempt to connect to the front port of the relay for communications over IEC 61870-5-103 will not be successful. In DIGSI software you can (and must) setup the relay's communication ports for the correct protocol and mappings. And you must use the front RS-232 port to connect and configure the relay through DIGSI. Hope this helps, Daniel Chartier |
