|---|---|---|---|
| WORD | - | 40 … 32767 | µs |
The input PULSE_WIDTH gives the time in microseconds which is used to increase the internal counter by 1. Also, this gives the minimal time available for switching on a binary output. All other times are a multiple of this time
PERIOD
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| WORD | - | 2 … 255 | PULSE_WIDTH length |
Period duration [in number of pulses], i.e. internal counter value is being set to 0 when this value is reached.
ON_DUR
| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| WORD | - | - | - |
