Counter
A digital 24 VDC up/down counter input is available in combination with up to two digital inputs/outputs. The function of these inputs/outputs depends on the configuration of SlotGroup 1.
Two of the inputs can also be used as digital 24 VDC outputs, with a current carrying capacity of 0.5 A per channel.
Optionally, one of the outputs can be set when a defined counter value is reached. This allows an exact reaction time independent of the fieldbus cycle.
The counting pulses are recorded via the "CNT Clk" connection point; only the rising edges are counted via "CNT Clk".
The counting direction is specified via the "CNT Dir" connection point and is defined as follows:
Level at connection point CNT_Dir | Voltage [V] | Counting direction |
|---|---|---|
Signal voltage "0 - LOW" | -3 V ... +5 V typ. | Forward |
Signal voltage "1 - HIGH" | 11 V ... 30 V typ. | Backward |

Be aware of bouncing when using electromechanical switches and push buttons When using electromechanical switches and push buttons, repeated closing and opening of the switch or push button can occur when the switch or push button is actuated, which is referred to as bouncing. Depending on the software filter set, these can be counted as pulses at the "CNT Clk" connection point.
