Hi , i am trying to get my GS2107 HMi to communicate with a FX3u-64M CPU through the rs-422 connection on the HMi's and the DM8m connector on the PLC side .
i struggled with this until finally getting a connection , but now for example , when the E-stop is healthy then it will display in green , and when E-stop is pressed it should display red ......
now all that is happening once comms is made my E-stop lamp stays green .(also if i remove the rs-422 cable the HMI still shows that the comms is connected .( PLC alive lamp and E-stop lamp stays green .)
