Scale Factors for PLC
Communication
The parameter values stored and produced by the SMC Flex through
communication are unscaled numbers. When reading or writing values from a
PLC image table, it is important to apply the proper scaling factor, which is based
on the number of decimal places.
Read Example
Parameter 11; Power Factor — The stored value is 85. Since this value has two
decimal places, the value should be divided by 100. The correctly read value is
0.85.
