Hello and good day I have a Mitsubishi fx1n-14mr PLC controlling a band saw. The PLC is connected via a DB925 - MD8M cable to a Beijer/mitsubitshi E100 HMI for communications and as a power supply via RS-422. When powered on the display on the E100 panel fluctuating, i.e. the screen turns on and off repeatedly. If the main switch is then switched off, then on again the screens seems to stay on and the machine operates normally. The PLC has a built in AC/DC power supply and I suspect that is may be the problem. Is is possible to switch out the AC/DC module? To make sure that the E100 panel is not the problem I want to connect a 5V external supply to the port located on the back. Is it safe to have the RS-422 and the 5V external supply connected simultaneously?
