My Friend is in Mexico working in an older machine, he calls me because after he did a Firmware upgrade of the processor from v20 to v24 his output modules in the rack stopped working. 1769-IW16 modules completely stopped working. There are no errors reported by the PLC, there is still Common power to these modules.
Reverting back to v20 didn't fix the issue. Deleting and re-adding the module to the project but that didn't work. Anyone have any thoughts? There are 4 IB16 modules then 4 IW16 relay output modules. The outputs aren't working but the inputs are.
Thanks.
