I would like the ability to toggle between celcius and farenheit

[Tectron]

I am using a V570 with a V200-18-E3/4XB snap in and a pt100 rtd on analog input 0. It is up in running, but I would like to make a config screen with the user option of selecting celcius or farenheit for all of the temperature functions. I noticed on the hardware config screen there is a dropdown in the mode field to select C or F, but how would I go about making this selectable from the touchscreen while its running?

Thanks

Hi Tectron,

The HW configuration can only be set for EITHER C or F. However, calculations can be done in the ladder using the math functions to convert one to the other. Once both C and F are stored into seperate operands, they can both be displayed on screen (or switch between the two).

Thanks

You can also store it in either C of F (why store it in 2 different parameters), and display in on the HMI Screen using Numeric variable. You can probably use the Linerarization of the Numeric variable in order to show the result in the desired format.

Thankyou for your replies, I have started trying to figure out how Im going to code this. I dont program every day so its a continual relarning process when I do. Does anybody know of an exaple program somewhere with similar functionality that I could refer to? I looked through the included exaples but I didnt really see anything that fit the bill.

Thanks
