I have an application that uses a P3000 with a Cmore EA9 6 " HMI. I have a utility screen with a change language button for English / Spanish, changing the verbiage is easy but one of the screens lists a number of temp readings in Fahrenheit and I want to change to Celsius when they press the Spanish button. Is there a simple way to do this? Thanks

I can only think of using the math function to convert F to C. You'd have to have a TEMP_Display tag, let's say, and when in English, you'd just direct the F temp to it, but when in Spanish, perform the math function on the F value, to convert it to C, and direct it to the TEMP_Display tag.

Another method is to use overlapping indicators. Control their visibility using the language choice. Each set will have the appropriate scaling conversion in the indicator.

I haven't tried the Math function yet, but what I have tried is adding a second rung below the first with the second scaled for Celsius, copied the screen for temperature and change the tags so they point to the Celsius outputs. I added a two button screen select marked F and C to change between the two. Seems like a clunky way to do it but will have to do until I can find a cleaner way. Too bad you cant use the Language2 setting to direct the display to the Celsius output.
I could not use the overlay and scale as the PLC already scales the output and I had overlays for High and Critical Temp warnings.
Thanks for the suggestions I'll keep looking for a cleaner solution.
