Jiri Posted April 8, 2019 Report Share Posted April 8, 2019 Hi, I've just downloaded for first time program to newly bought V280 OPLC , and the display is empty. It's empty even when going to system settings or during restart - no system massages. Program works on background, I can connect to PLC using RemoteAccess utility, so I can see screens working. I tried to re-download operating system again, but nothing helped. Does anybody knows what else to do? Thanks, Jiri Quote Link to comment Share on other sites More sharing options...
DanT Posted April 8, 2019 Report Share Posted April 8, 2019 Hi Go Online with the PLC Look At SI7 V280 LCD Contrast should be 50 to 100 Also Look at SI9 LCD Back Light Intensity -- 0,1,2 I believe DanT Quote Link to comment Share on other sites More sharing options...
Cam Posted April 8, 2019 Report Share Posted April 8, 2019 Check the value of the back light and contrast SI's SI7 and SI9. Quote Link to comment Share on other sites More sharing options...
DanT Posted April 9, 2019 Report Share Posted April 9, 2019 Further question-- When the PLC was first powered up, before download - was there data showing on the display? If not - maybe an internal connector. else - check your program and SI noted above. DanT Quote Link to comment Share on other sites More sharing options...
