Using PE functions designed to take multiple arguments (Minimum, Maximum, Average) with just one argument causes undesired behavior.
Functions expecting more than one argument require that more than one argument is passed.
Make sure to always pass at least two arguments to PE functions that are designed to take multiple arguments such as Minimum, Maximum, Average etc
OAT = Minimum(MyNetwork\MyCX\Myi2Device)
The line above may cause undesired controller behavior
Replace the line above with the following line
OAT = MyNetwork\MyCX\Myi2Device
