Hi all,
I'm trying to fit a CP343-1 Lean card (v3.0 6GK7 343-1CX10-0XE0) on to an existing rack that has a CPU318-2 (6ES7 318-2AJ00-0AB0) in slot 2 and a input interrupt card (6ES7 321-7BH00-0AB0) in slot 4.
Initially I dropped the Lean card into slot 5 but found that the lean card wasn't working. I thought it could be a fault backplane etc so tried swapping the interrupt card and back connectors with spares but to no avail.
I then put the lean card in slot 4 and the interrupt card in slot 5 and the lean card worked. Unfortunately then the machine bombed out on a error to do with it's clock pulse. I think the error is because it isn't getting it's clock pulses quick enough. If I 'inch' the machine slowly it all works fine.
The addresses haven't changed on the interrupt card and I can't see anything that would effect its functionality by being moved into a different slot.
Has anyone got any ideas on what might be happening here? Could the 'lean' card be slowing the backplane comms down so much as to make the interrupt card not work?
Or does the interrupt card *have* to be in slot 4?
Or is there any other reason you can think of why this configuration wouldn't work?
Many thanks
;-)
