Older PLC systems are becoming obsolete and hard to find parts for maintaining a reliable system. We can provide an upgrade to the latest PLC technology of your choice. Our in-house controls team can provide the PLC programming and HMI modifications required. New PLC racks are preassembled and programmed at TANN (if program is available) making for a quick installation. We also offer options to retrofit existing racks with newer processors. Contact us today to discuss your PLC upgrade solutions.
