carver Posted February 15, 2013 Report Share Posted February 15, 2013 I have 3 PLCs V350-35-TA24. All are loaded with the same program. SI9 is set to 75 on all PLCs. One of them has very low contrast, so it's not possible to distinguish differnt shades of gray. Is there a way to adjust contrast? Link to comment Share on other sites More sharing options...

carver Posted February 17, 2013 Author Report Share Posted February 17, 2013 Hi Emil SI7 is for V120/280/290 only and actually it does not change anything. Link to comment Share on other sites More sharing options...
Emil Posted February 17, 2013 Report Share Posted February 17, 2013 Right, sorry. Please take a picture of the display with low contrast and send it with S/N and value of SI9 to support@unitronics.com. We will investigate the problem. Link to comment Share on other sites More sharing options...
carver Posted February 18, 2013 Author Report Share Posted February 18, 2013 Hi Emil The customer ignores the "problem". Otherwise he would has to dismantle the plc which is a to big effort. Anyway, thank you. Peter Link to comment Share on other sites More sharing options...
albert Posted February 24, 2013 Report Share Posted February 24, 2013 hi i am a newby on programming a v350 doing this for 3 weeks, trying to get things started actually si7 does not work, tried it also, but si9 does (brilliance) see attached pdf may be not a 'legal solution', using bitchanges in the same net, but it works. MB4 is set (or reset) to decide adding or substracting SI9.pdf Link to comment Share on other sites More sharing options...
