PSM Logic Functions, Threshold Switch Function - GF54.21-D-3209TSA
Model 907
with code ED5 (Parameterisable special module)
Threshold switch, function
The threshold switch has an analog input (E) with 16 bit width and 4 digital outputs (Aa, Ab , Ac , Ad ). The input (E) is an encodable filter connected in series.
The input value is compared with up to 4 threshold values (A, B, C, D) and then the relevant output set (AA , Ab , Ac , Ad ).
When coding the threshold switch the parameter threshold value (Psa Psb , Psc , Psd ) must match the following coding specification:
Threshold value (A) < Threshold value (B) < Threshold value (C) < Threshold value (D).
If this coding specification is not followed the characteristic of the threshold switch is not defined.
For outputs (AA , Ab , Ac , Ad ) a run point or a bar graph function can be coded.
Signal identification number = Signal ID.
| Input (E) | Output (AA ) | Output (AB ) | Output (AC ) | Output (AD ) |
|---|---|---|---|---|
| Input (E) ← Threshold value (A) | 0 | 0 | 0 | 0 |
| Threshold value (A) < Input (E) ← Threshold value (B) | 1 | 0 | 0 | 0 |
| Threshold value (B) < Input (E) ← Threshold value (C) | 0 | 1 | 0 | 0 |
| Threshold value (C) < Input (E) ← Threshold value (D) | 0 | 0 | 1 | 0 |
| Threshold value (D) < Input (E) | 0 | 0 | 0 | 1 |
| Input (E) | Output (AA ) | Output (AB ) | Output (AC ) | Output (AD ) |
|---|---|---|---|---|
| Input (E) ← Threshold value (A) | 0 | 0 | 0 | 0 |
| Threshold value (A) < Input (E) ← Threshold value (B) | 1 | 0 | 0 | 0 |
| Threshold value (B) < Input (E) ← Threshold value (C) | 1 | 1 | 0 | 0 |
| Threshold value (C) < Input (E) ← Threshold value (D) | 1 | 1 | 1 | 0 |
| Threshold value (D) < Input (E) | 1 | 1 | 1 | 1 |
| Designation in data entry table | Data entry bit width | Data bit evaluation | Meaning |
|---|---|---|---|
| B1_G1_SS1_threshold_A | 16 bit | - | Encodable threshold value (A) |
| B1 G1 SS1 threshold B | 16 bit | - | Encodable threshold value (B) |
| B1_G1_SS1_threshold_C | 16 bit | - | Encodable threshold value (C) |
| B1_G1_SS1_threshold_D | 16 bit | - | Encodable threshold value (D) |
| B1_G1_SS1_mode | 1 bit | Adjustment value: Bar graph → 0 Sequential point → 1 |
|
| B1_G1_SS1_signal_ID | 32 bit | 16 bit | Filter + signal-ID input signal data entry |
| Designation in signal ID list | Data bit width | Meaning |
|---|---|---|
| Out_G1_SS1_A | 1 bit | Signal ID of output (AA ) |
| Out_G1_SS1_B | 1 bit | Signal-ID of output (AB ) |
| Out_G1_SS1_C | 1 bit | Signal-ID of output (AC ) |
| Out_G1_SS1_D | 1 bit | Signal-ID of output (AD ) |
The same applies for the other threshold switches with the naming conventions:
- "B<Block number>_G<Group number>_SS<Number>_Threshold_(A, B, C, D)"
- "Out_G<Group number>_SS<Number>_(A, B, C, D)"
