Operands:
S: Variable resistor number (0~1) D: Destination device for storing scaled value
Explanations:
VRSC instruction reads the scaled value (0~10) of the 2 VRs on PLC and stores the read data in
destination device D as an integer, i.e. if the value is between 2 graduations, the value will be
rounded off.
Program Example 1:
When X0 = ON, VRSC instruction reads the scaled value (0 to10) of VR No. 0 and stores the read
value in device D10.
X0
VRSC K0 D10
Program Example 2:
Apply the VR as digital switch: The graduations 0~10 of VR correspond to M10~M20, therefore only
one of M10 ~M20 will be ON at a time. When M10~M20 is ON, use DECO instruction (API 41) to
decode the scaled value into M10~M25.
1. When X0 = ON, the graduation (0~10) of VR No.1 will be read out and stored in D1.
2. When X1 = ON, DECO instruction will decode the graduation (0~10) into M10~M25.
