Marko984 Posted January 6, 2018 Report Share Posted January 6, 2018 Hello; Im using V430-J-R34 and Encoder RSI 503 Leine Linde, and im doing something wrong. Both encoder and PLC have power, In configuration I have set HSC0 to (A,B) Shaft Encoder X2 and link it to MI1. Encoder is connected yellow (S00) to I0(A) and green(S90) to I1(B) Numeric Variable on HMI is linked to MI1 And nothing.. its not counting up or down, value is 0 all the time. I'm missing something but I don't know what, oh and PLC is configured to PNP (by default). Please help Tnx in advance Marko Quote Link to comment Share on other sites More sharing options...
MVP 2022 Joe Tauser Posted January 6, 2018 MVP 2022 Report Share Posted January 6, 2018 You've got the PLC configured correctly. You did not give us the full encoder part number with the supply voltage and output type. The picture I found online of an RSI 503 showed a 5V power supply. Joe T.

Marko984 Posted January 6, 2018 Author Report Share Posted January 6, 2018 Thank you for fast replay, here is data Encoder RSI 503 Part no 515415-05 Ser. no. 22978714 Supply: 9..30Vdc Output: 100 pprHTL Marko Quote Link to comment Share on other sites More sharing options...
MVP 2022 Joe Tauser Posted January 8, 2018 MVP 2022 Report Share Posted January 8, 2018 Thanks for the datasheet. What happens when you put a voltmeter on I0 and I1? Joe T. Quote Link to comment Share on other sites More sharing options...
Cam Posted January 8, 2018 Report Share Posted January 8, 2018 For some HTL outputs external diodes are required in order to make them operate and replace a NPN or PNP output. Also worth noting that your output voltage is typically your min supply voltage -3V are you still meeting the min voltage for a logical high?

Marko984 Posted January 9, 2018 Author Report Share Posted January 9, 2018 Cam, I am working whit stable 24VDC supply, but that is good to know, tnx Found the problem, wire from 0 V was damaged in cable (15m), had to replace the encoder. I will find a different use you that encoder. Thank you very much for your responses. Its nice to know I can count on this community and on Joe T. who is always responding to my newbie troubles.
