omerelektrik Posts: 23 Rating: (0)	Hello dear my friends; Firstly I am sorry for my poor English. I have a few questions for digsi and siprotec. 1 ) Ihave 12 siprotecs 7sj6225. I connect them to back port B from my computer. But my computer will be far away from siprotec devices. I want to use westermo (odw-730 and odw720). these devices convert to RS232 / Fiberoptic and RS485 / Fiberoptik. But I cant connect to siprotec over westermo. I communicate 2 PCs from Hyperterminal over westermo devices. Although this I cant connect siprotec. Did anyone face to this problem ? How can I connect to siprotec over converters? 2 ) There are lots of alarm leds which are defined on siprotec devices. I want ot show these alarms in my scada project but I dont know these alarms adresses. How can I find these adress or something like that. 3 ) And finally I want to calculate energy. In pdfs calculation there is I and U but I cant see these parametres in adress maping. How can find these parametres? Thanks and best regards...

I don't know any Profibus RS485 to Modem converter. Maybe other colleagues may help. 2. You don't send LED information to Scada, but the information- the one which you configured to set theLED -itself. 3. Siprotec calculates energy for you, as soon as you read current and voltage. On the matrix there are filters and you have to select the measurements, instead of IO. Mike
