Thanks I did read that manual. but again the memory logs don’t help much with the fault codes 

 

I’m sure the special IO address is correct. it is set to machine number 0 and is coded in the IO table to 100

ill get back to it tonight.   but from what I tried last time the IO tables will always go blank after a power cycle. I upload the Tables separately, but still no operation of the machine and the same fault listed above. How do I check the dial settings you refer too?

Omron with a error we can not clear old machine which has a lot of different people working on if, I have been left with it like this. I would like to see if I can get it going.    0x00D0 Duplex / Special IO unit error. I see this as a CPU error but the old parts are hard to come by.    any ideas ?

Why would a plc output have a toroidal / ferrite core on it? It is a output to a safety relay, ‘dc enable for Cat0’ (I know drawing States solenoid but it goes to the safety relay) there is no fault, I just want to know why. Please include reference material of possible.
