Hey Guys,
So I am lucky enough to be neck deep with an old piece of machinery that is controlled by Siemens S5 gear.
It is here that I should say that my experience lies mostly on the Allen Bradley side of town, but that is not enough to scare me off.
I was forced to reload the PLC program after I found that the memory blocks had somehow became corrupted. The steps I took consisted of clearing out the memory, resetting all of the hardware settings to default, and transferring the program. I really didn't want to clear out the memory and reset all of the hardware settings, but this was the only way I could get a successful download to the processor.
I now have a stable processor communication wise, but the fault I now have is that it cannot see the expansion rack. I get a fault "Delayed Handshake from Peripheral", and when I go to diagnose this fault it points me to the peripheral input load block and the section of code lines up exactly with the first card of the expansion rack.
I feel that perhaps when I reset the hardware configuration settings, perhaps I messed something up to do with the expansion rack and how that is setup.
Either that, or I have some faulty hardware that I will have a lot of trouble finding spares for!!
Does anyone have any experience that they could share with me along these lines??
I am just about to sink into the manuals..
