Model 448
With Code ED5 (Parameterisable special module)
Except Code XM7 (MOPF II)
Parameterizable special module (PSM) arithmetic, differentiator/integrator, function
As differentiator:
- Result (E) = (Scaling factor 1/Scaling factor 2) * W (t) - W (t-1); t, (t-1) = Time base
As integrator:
- Result (E) = (Scaling factor 1/Scaling factor 2) * W (t) + W (t-1); t, (t-1) = Time base
Where:
- W (t) is the value (W) at the input at time t.
- W (t-1) is the value (W) at the input at time t-1.
Reset (R) = "1"→ (E) = "0" (Reset an integration, deactivation of integrator or differentiator at any time)
Result (E) > Upper limit (Lim. High) → Result (E) = Upper limit (Lim. High)
Result (E) < Lower limit (Lim. Low) → Result (E) = Lower limit (Lim. Low)
Signal identification number = Signal ID.
CODING

| AU_DiffInt_1_Cfg | "Unsigned" 8 bit | Configuration for calculation step assignment (Schritt 1...4 = (0...3)) and calculation specification: "0" = Differentiator "1" = Integrator |
| AU_DiffInt_1_Timebase | "Unsigned" 16 bit | Time base in cycles of the programmable logic controller (PLC) (increments of 20 ms) |
| AU_DiffInt_1_F1 | "Unsigned" 16 bit | Scaling factor |
| AU_DiffInt_1_F2 | "Unsigned" 16 bit | Scaling factor |
| AU_DiffInt_1_Lim_High | "Signed" 32 bit | Upper limit (Lim. High) for result (E) |
| AU_DiffInt_1_Lim_Low | "Signed" 32 bit | Lower limit (Lim. Low) for result (E) |
OUTPUTS
| Designation in signal ID list | Data bit width | Meaning |
|---|---|---|
| Out_AU_Diff_Int_1 | "Signed" 32 bit | Differentiator/integrator output result (E) |
The same applies for other differentiator/integrator blocks with the naming convention:
- "AU_DiffInt_<Differentiator/integrator block number>_<Parameter designation>"
- "Out_AU_Diff_Int_<Differentiator/integrator block number>"
- Configuration Tool 1 of the programmable logic controller (PLC) can be used to generate a corresponding coding string.
