Hello Saggy; Yes, that is starting to be apparent, and you have not chosen the easiest task to start learning Profibus-DP comms, as the relays require seperate configuration (through DIGSI 4 software) and distinct data exchange mappings.. You do not need specialized blocks in the PLC to echange data with a Siprotec relay. All data is configured as "consistent over unit" which means that you can simply read all values configured through the mapping directly from the configured address (you will see these addresses in the HWConfig). You can also use SFC 15/SFC 14 to read data consistently (large amounts of data transfered at once time); the mechanism is explained in section 4.5 of the following document: Communication module - SIPROTEC |

Hello Saggy; What are these ports on the Siprotec relay of yours? http://www.energy.siemens.com/ecc_pool/SIPROTEC4/881f03d4-7d96-49d2-b314-01826026699e/7SJ62_Catalog_SIP_E7.pdf Serial front interfaceThere 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. http://www.energy.siemens.com/ecc_pool/SIPROTEC4/0bce6147-2988-4bbd-a83b-99efe39e2a3c/7SJ62-64_Manual_A6_V044001_us.pdf You have been given many links earlier in this thread, you should find much information there. The projects I have worked with do not belong to me, so I can only give you pointers to what has to be done. The following link leads tpo the Siprotec relays download area, format it as shown in the attach,ment below to locate all availab;le manuals dans pdfs on the 7SJ62 relay:
