I am using Maple systems HMI with Carel PLCs connected through RS485. I am having a problem with the HMI toggle buttons. Doing the offline simulator lets me toggle, but when i upload it to the actual display, I cannot.
I am also getting some readings that are showing xxx instead of a number. Does that mean I have something wrong with the logic or is the display the problem?
And my last question is the HMI will freeze up within a few minutes after turning on. What could be the cause of this? A defective display?
Any suggestions for these problems would be greatly appreciated!
