Changing an analog value via HMI

RiRa Posts: 10 Rating: (0)	There is an thermal system with three analog values: X:room temp. Y:set point A:control signal I'd like to change the setpoint with my TP170A. When I try to change it,(that is in MW2) nothing happens I've used IO field and also a button's SetValue function. Thanks.

Just connect your tag with the I/O field. Is the MW2 overwritten inside the PLC?

If you change the power tag in HMI and the power tag is changed in the PLC, too , then youcan never modify the power tag via HMI. power tag = HMI tag which has a connection to a PLC tag After eachentry you have topress the enter key to confirm your input. If you don't do that, thenyou don't changethe value of the tag. Bye
