Hi.We setup S7-300 pn/dp cpu and Control tecniques emerson unidrive m200 series on ethernet.Installed gsd file communication ok.I selected input parameter 4 times user defined 32 bit read and output parameter 4 times user defined 32 bit write in flexible modules.Assignment adresses from 256 to 271 in hardware config.windows.Everythings were seem good.When I write FC100 inside a program like this,
L PIW256
T DB100.DBW0
L PIW258
T DB100.DBW2
etc...(ıt is calling OB1)
When I want transfer FC100 to plc ''unable to block transfer message is shown.
The other question must I use SFC14 and SFC15 blocks for ethernet communication?Thanks in advance...
