Hi all,
I am trying to get my head round Profinet comms.
I need to communicate with a Robot that has a profinet card fitted.
The card is set to 32bytes in and out. IP address and name are set.
Using an S7 313C with a CP-343-1. The node is set on the profinet network in the hardware config and the CP-343 is 'seeing' the node. When the remote card is powered down the 343 -1 goes into fault and when the remote card is powered up the fault goes off.
The bit I'm struggleing with is getting the data, from looking through various manuals I believe I need to use PNIO_SEND and RECV.
What is the CPLADDR refering to?
I attach the hardware config of the rack, node and the PNIO_SEND and RECV rung.
Currently I have put 190 in the CPLADDR as it's hex for 400 which is the I/O start address of the module???
Thanks for reading, any pointers gratefully received....
