function refused by cpu #57

Closed celevra closed 5 years ago

celevra commented 5 years ago

Hi,

is it also possible to communicate with Tia Portal 1500?

regards

Celevra

Johanneslueke commented 5 years ago

To my knowledge this is not possible because the TIA Portal only acts as a client.

celevra commented 5 years ago

hm could be that its not really clear what i ment ;-) programming a Siemens 1500 isn't done in S7 today but via the new TIA Portal. I thought that it could be possible that the problems with function refused by cpu is because of that

Yes it is possible to communicate with Siemens S7 plc's. What specific function is giving you this error?

Johanneslueke commented 5 years ago

@celevra ok if you meant an actual s7-1500 then yes it is possible. reading writing does work fine. i haven't tried out with an R/H-systems while those are in RunRed. But standalone does work fine. Communication is done via S7-Protokoll.
