I am asking on here in case anyone has come across this before.
I have also asked it on mrplc.com to try reach a wider audience as I am a little baffled.
A customer has an E1070 HMI connected to an FX1n.
Everything has worked perfectly for years until one day...........
The HMI was only 'half' communicating with the PLC
By that I mean, I could see values in registers on the screen and the LED's were working but none of the buttons were working.
I connected to the HMI with a CAB30 cable and got the HMI program out but I could not communicate with the PLC in transparent mode.
I connected to the PLC with an SC09 cable and got the PLC program out.
They bought a brand new E1070 HMI and a new plc connecting cable and I put the HMI program in it and all worked great again.
But! even with the new HMI and cable, I still couldn't connect in transparent mode.
Nothing was touched on the screen, I fitted it as it came out of the box (no dip switches touched etc)
Are there any obvious settings I might be missing?
My CAB30 is fairly new and it did work perfectly on another project. (so I don't suspect that)
I of course ticked the 'transparent mode' box in communication settings and I also tried several baud rates but I could not communicate with the plc
Any suggestions?
