I have a Omron CP1L PLC that I'm having problems communicating with a NS5-SQ11B-V2 Omron HMI through ethernet . I have the exact same set up on other projection welders . After installing the HMI and PLC I copied the PLC program and HMI from a welder that is working and transferred it to the new welder but I have no communication from PLC to HMI.
