Hi All,
this is my first experience with the Siemens CP343-1 Profinet used as I/O Controller for manage ET200M remote I/O.
Here my actual configuration:
Main rack:
1) CPU315/DP
2) 16 x 24 Vdc digital input
3) 16 x 24 Vdc digital output
4) CP343-1 Lean
5) CP343-1
Remote I/O ET200M station
1) IM151
2) 16 Digital In + 16 Digital Out 24 Vdc
PLC code developed with Step7 v5.5
The problem I'm facing is inside PLC program I'm not read or write the I/O in the ET200M remote station.......
The CPU 315 and CP341-1 leds are all OK.....not BF or SF fault, all processors led of RUN are ON.
DUring the compile program download hardware no problem everythings is Ok.
I try also to send a ping to the different unit.... CPU, CP etc. etc. and I get the right answer......
So reading the manual of CP341-1 is not clear to me if I need to use the instruction PNIO_SEND and PNIO_RECV to manage the inputs-outputs in the ET200M, or what I would have expected is possible direcly read the inputs and write the outputs using only the address assigned in the hardware during the setup of ET200M module.
Thanks in advance for your tips
