Invalid PV Span

Was bedeutet PVSpanInv (Status1.4) ?

This fault indicates an invalid span configuration for the Process Variable (PV), specifically when PVEUMax is less than or equal to PVEUMin. In the PPID instruction, the equivalent Sts_ErrPVEU is set when Cfg_PVEUMin is greater than Cfg_PVEUMax, or if Cfg_PVEUMin or Cfg_PVEUMax is configured as Infinite (Inf), Negative Infinite (-Inf), or Not-a-Number (NaN).

• PVEUMax parameter configured to be less than or equal to PVEUMin (PIDE)
• Cfg_PVEUMin parameter configured to be greater than Cfg_PVEUMax (PPID)
• Cfg_PVEUMin or Cfg_PVEUMax parameter set to Inf, -Inf, or NaN (PPID)

1. 1

   Access the PIDE or PPID instruction configuration within the programming software

2. 2

   Verify PVEUMax (PIDE) or Cfg_PVEUMax (PPID) is numerically greater than PVEUMin (PIDE) or Cfg_PVEUMin (PPID)

3. 3

   Ensure Cfg_PVEUMin and Cfg_PVEUMax (PPID) are valid numerical values and not Inf, -Inf, or NaN

4. 4

   Adjust the PV scaling limits to a valid range, e.g., Cfg_PVEUMin = 0.0 and Cfg_PVEUMax = 100.0
