Input Description¶
X
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| INT | - | - | - |
The operand for the controlled variable is specified at input X.
T1_TZ
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| INT | - | - | - |
The integration time is specified at input T1_TZ. In this case, it must be scaled to the cycle time. During the time T1, the output Y of the integrator changes by the value KP * X.
Value range: 0 ≤ T1_TZ ≤ 328
- If values are specified which are beyond the admissible value range, the PLC generally uses the value 328.
- A large integration time (T1) can be achieved by choosing a large cycle time, too. If the Function Block is used within a run number block, the cycle time of the run number block is valid for INTK and not the cycle time of the PLC program.
RES
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
The output Y can be reset to the value 0 with the input RES. Integration then begins as from the value 0.
STOP
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
The output can be latched to the current value by means of the STOP input.
STOP = FALSE → Output not latched
STOP = TRUE → Output is latched
The STOP input has higher priority than the inputs S and R.
SET
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
With the input SET, the manipulated value Y can be set to the initial value at input INIT. Integration then begins as from the initial value.
SET = FALSE
→ No setting
SET = TRUE
→ Output Y is set to the specified initial value.
*) Priority sequence for the inputs STOP, SET and RES:
RES highest priority
STOP
SET lowest priority
INIT
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| INT | - | - | - |
The initial value to which the output is to be set if required is specified at input INIT.
KP
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| INT | - | - | - |
The proportional coefficient is specified at input KP. It serves to weight the controlled variable at input X. Weighting is achieved by multiplying the controlled variable by the proportional coefficient. The proportional coefficient is specified as a percentage.
Example:
| KP | is equal to | Meaning |
| 1 | 1 percent | The Function Block multiplies the value at input X by the factor 0.01 |
| 55 | 55 percent | The Function Block multiplies the value at input X by the factor 0.55 |
| 100 | 100 percent | The Function Block multiplies the value at input X by the factor 1 |
| 1000 | 1000 percent | The Function Block multiplies the value at input X by the factor 10 |
| -100 | -100 percent | The Function Block multiplies the value at input X by the factor -1 |
OG
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| INT |
The manipulated variable Y can be limited to a value range. The high limit for the manipulated variable Y is specified at input OG.
UG
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| INT | - | - | - |
The manipulated variable Y can be limited to a value range. The low limit for the manipulated variable Y is specified at input UG.
