We have an omron CJ2M-CPU12 PLC that we are having issues with an AD04U analog card. it is connected to a K type thermocouple sensor. The card is not seeing the sensor and not reading sensor. Our maintenance team changed the sensor out with a new one and also changed the analog card. Same results. We thought maybe the output card that the analog card was connected to had a faulty connection to the card. So we changed the output card with a new one with the same results. We are getting all these errors in IO table for the analog card settings. We have researched and can not find an issue. Maintenance has even tried changing out the PLC. Same results. All the original equipment is reinstalled but not running. Anyone have any suggestions?
