I have an add on instruction, which I am using inputs as parameters used in the instruction. I have the inputs set up as required and visiable with read/write access.
I'm not changing these values from within the Add on Instruction, but I do want to be able to change these parameters from an HMI.
I set up the AOI and it added the variables for my input parameters according to the AOI user defined type. However if I try to change these tags either from within the HMI or the program, then they revert back to the previously downloaded values. The only way to change the values, is to edit the rung, and then accept the changes.
Do I need to uncheck the required field in the add on instruction? I do want the tags to be generated as part of the AOI variable, and to be able to modify them outside of the add on instruction.
