Hi,
I have a Siemens 313 CPU which has no profibus port. Instead of buying a new CPU, we ordered a CP342-5 profibus card.
I have written standard blocks for PPO + PKW communication with omron frequency drives. This was written and tested with a 315-2DP CPU.
Okay, we want to communicate with the 313 + CP342 to the omron drives. The CP342-5 has to be master and the drives are slaves.
I know CP342-5 cards are used for communication between networks, I hope it can be used to be master for drives as slaves ?
I connected 3 drives on the CP342-5 and did my configuration in the HWconfig. I get BUSF on the CP342-5. When I look into diagnostics, the CP can see the nodes, but I get faults.
Can anyone give me more information about the problem I have ?
Here some screenshots:
