Hi all,
I have a problem with a 317-2 Technology CPU. The point I’m at now is that via PG/PC interface via Profibus I can test the port and get OK then read I get 0 and 2 ticked (laptop and CPU).
In accessible nodes is see DP=2 But going via the ONLINE tab the CPU is grayed out and connection via HWconfig is not possible.
As I am testing this off the machine I only have the CPU powered up, nothing else connected.
This is a flow of what I’ve done.
· Default CPU settings initialised so MPI/DP port is now MPI = 2
· PG/PC interface MPI diagnostics show OK and READ shows 0 (laptop) and 2 (CPU)
· Accessible nodes shows MPI=2
· Hardware Config wont connect (offline MP/DP address changed from Profibus 12MPS to MPI, save/complie)
· Hardware config now connects and I can download config onto CPU
· All blocks can also be downloaded onto CPU
· View CPU via ONLINE tab shows all blocks
· View hardware config ONLINE shows CPU state
HOWEVER CPU needs to be on the Profibus 12MPS network for remote I/O
· Change Offline hardware config to Profibus 12 MPS and networked = YES
· Download via MPI onto CPU – warning that PG/PC needs changed after download performed.
· Change PG/PC interface to Profi 12 MPs and (diagnostic shows OK and READ shows 0 and 2) ( MPI now shows transmission error)
· Accessible nodes shows Profibus = 2
· Go ONLINE tab to CPU and CPU is grayed out (blocks not viewable)
· Go to Hardware config ONLINE and error for online not possible.
Its as if the Profibus port cannot read into the CPU but the MPI part can?!
