Input Description¶
EN
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
In order to enable pulse counting for input CH, input EN has to be continuously set to TRUE. The Function Block is not processed if input EN = FALSE.
When calling the Function Block the first time, the inputs are checked for validity and plausibility. If this is not the case, processing is aborted and a corresponding error is displayed at output ERR/ERNO.
MODULE_ADR
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BYTE | - | 0 … 29 | - |
At input MODULE_ADR, the address set at the CS31 Bus Module is entered.
COM
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BYTE | - | - | - |
At input COM, the number of the serial interface is specified to which the CS31 Bus Module is connected.
Valid values are 0 and 1 for COM1 and 2 for COM2 (only CM574-RS).
EN_VISU
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
If input EN_VISU = TRUE, it is also possible to control the Function Block inputs (except SLOT, COM, MODULE_ADR, EN and EN_VISU) via the integrated visualization of the Function Block. If input EN_VISU = FALSE, control via the visualization is disabled and the labelling of the corresponding control elements is displayed in gray. The actual values are always displayed Visualization.
EN1
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
If input EN1 = TRUE, pulse counting of counter 1 is enabled. If EN1 = FALSE, no pulse counting is performed and the pulses are lost.
Input EN1 corresponds to bit 1 in control byte 0.
UD1
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
At input UD1, the counting direction is set for operating modes with up/down counters (modes 3…6).
The following applies:
UD1 = FALSE → counter 1 counts up
UD1 = TRUE → counter 1 counts down
If input SET1 = TRUE, the counter takes this value.
Input UD1 corresponds to bit 0 in control byte 0.
EN_OUT1
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
Input EN_OUT1 is used to select the output control mode for the operating modes with direct output activation (modes 1 and 2).
Only for fast counter operating modes 1 and 2:
If EN_OUT1 = FALSE, the related digital output DO acts as an output indicating “end value reached” of the fast counter.
If EN_OUT1 = TRUE, the related digital output DO can be used as normal digital output.
The value change of EN_OUT1 is only effective when EN = TRUE.
Input EN_OUT1 corresponds to bit 3 in control byte 0.
SET1
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
If set input SET1 = TRUE, the counter takes the values from the inputs UD1, START1 and END1.
As long as input SET1 = TRUE, no pulses are counted because the counter is always overwritten by the start value START1.
Input SET1 corresponds to bit 2 in control byte 0.
START1
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| DWORD | - | - | - |
At input START1, the start value of counter 1 is entered.
If input SET1 = TRUE, counter 1 takes this value.
Input START1 corresponds to the analog outputs 0 (bit 16..31) and 1 (bit 0..15) of the CS31 Bus Module.
END1
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| DWORD | - | - | - |
At input END1, the end value of counter 1 is entered.
If input SET1 = TRUE, counter 1 takes this value.
Input END1 corresponds to the analog outputs 2 (bit 16..31) and 3 (bit 0..15) of the CS31 Bus Module.
UD2
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
At input UD2, the counting direction is set for operating modes with up/down counters (modes 3…6).
The following applies:
UD2 = FALSE → counter 2 counts up
UD2 = TRUE → counter 2 counts down
If input SET2 = TRUE, the counter takes this value.
Input UD2 corresponds to bit 0 in control byte 1.
EN_OUT2
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
Input EN_OUT2 is reserved. A variable with the value FALSE has to be applied.
Input EN_OUT2 corresponds to bit 3 in control byte 1.
SET2
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
If set input SET2 = TRUE, the counter takes the values from the inputs UD2, START2 and END2.
As long as input SET2 = TRUE, no pulses are counted because the counter is always overwritten by the start value START2.
Input SET2 corresponds to bit 2 in control byte 1.
START2
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| DWORD | - | - | - |
At input START2, the start value of counter 2 is entered.
If input SET2 = TRUE, counter 2 takes this value.
Input START2 corresponds to the analog outputs 4 (bit 16..31) and 5 (bit 0..15) of the CS31 Bus Module.
END2
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| DWORD | - | - | - |
At input END2, the end value of counter 2 is entered.
If input SET2 = TRUE, counter 2 takes this value.
Input END2 corresponds to the analog outputs 6 (bit 16..31) and 7 (bit 0..15) of the CS31 Bus Module.
