Last night electricians replaced the panelview and now there is no comms between the panelview and the PLC.
The processor is a 1747-L541 SLC 5/04 and has a 1747-SN scanner that connects to the HMI.
The Scanner is faulted out and has a flashing red fault led. The HMI has no comm or fault led's on.
Im not sure where to go from here.
I have a feeling that when the progam was downloaded onto the replacement HMI, the wrong address was assigned to the HMI which is causing issues. Im not sure though, I've never worked with these old HMI's.
Any help would be appreciated.
