Mirko Pohland commented on PLC4X-134:
-------------------------------------
Hi everyone,
I tried the same with an S7 1200 and it worked like expected. What worked for
both, the S7 300 and the S7 1200 was to add rack and slot to both, the calling-
and the calledTsapId.
short calledTsapId = S7TsapIdEncoder.encodeS7TsapId(DeviceGroup.OS,
rack, slot);
short callingTsapId =
S7TsapIdEncoder.encodeS7TsapId(DeviceGroup.PG_OR_PC, rack, slot);
I am not familiar enough with the IsoTPProtocol to know why this works. But it
still might be of some interest for you.
Regards,
Mirko

> Now I can connect to the S7.
