In the UTAdvanced series, if I change the input ladder and then write the PV value from the PLC to the P parameter (P01) through communication, the digits of the PV value are shifted. How can I correct that?

In the UTAdvanced series, if I change the input ladder and then write the PV value from the PLC to the P parameter (P01) through communication, the digits of the PV value are shifted. How can I correct that?

Match the control PV input decimal place (P.DP) with the decimal place (P1D) setting of the P parameter (P01). If they are different, the display digit of the PV value will be shifted.
The decimal place (P1D) of the P parameter (P01) is not displayed on the controller main unit. To change the settings, use LL50A Parameter Setting software.

Example: To write the PV value to P01 and display it to one decimal place:

  • Setup Parameters > MPV > P.DP = 1
  • Operating parameters > PPAR > P1D = 1
