Pot wiper inputs
Setup_POT(2)
This function sets the type of input that will be connected to each of the four analog
inputs. The system uses the concept of a potentiometer and thus these inputs are
called Wiper inputs. The inputs can be set up as one-wire, two-wire, or three-wire,
referring to the number of wires connected from the pot to the 1310. A one-wire pot
is a voltage input (0–5V), and connects to a Wiper input; a two-wire pot (rheostat)
connects with the Wiper and Pot Low signals; and a three-wire pot connects with
the Pot High, Wiper, and Pot Low signals. Note that this function does not enable
any fault checks. Fault checks must be done by custom VCL code.
Data Values
Pot#_Output Variable that is automatically updated with the value of
the wiper input.
Parameters None.
Pot_ID Identifies which wiper input is used (POT1 – POT4).
Type Identifies which type of pot is connected (ONE_WIRE,
TWO_WIRE, or THREE_WIRE).
