Setting and changing the pulse on-load factor
OUTPUT_VALUE assigns the on-load factor for the current period duration. You select the
range of the field OUTPUT_VALUE of the control interface with the "Output format"
parameter.
● Output format per 100: Value range between 0 and 100
Pulse duration = (OUTPUT_VALUE/100) x period duration.
● Output format 1/1000: Value range between 0 and 1 000
Pulse duration = (OUTPUT_VALUE/1 000) x cycle duration.
● Output format 1/10000: Value range between 0 and 10 000
Pulse duration = (OUTPUT_VALUE/10 000) x cycle duration.
● Output format "S7 analog output": Value range between 0 and 27,648
Pulse duration = (OUTPUT_VALUE/27 648) x period duration.
You assign OUTPUT_VALUE directly via the control program. A new OUTPUT_VALUE is
applied at the output when the next rising edge occurs.
Setting and changing the period duration
● Permanent updating
The period duration is permanently controlled via the control interface. The MODE_SLOT
bit must be set ("1" means permanent updating); LD_SLOT must be set to value 1 ("1"
means period duration). Set the period value in the field SLOT. The unit is always a
microsecond.
– High-speed output activated: between 10 μs and 10 000 000 μs (10 s) in the field
– High-speed output deactivated: between 100 μs and 10 000 000 μs (10 s) in the field
– Standard output (100 Hz output): between 10 000 µs (10 ms) and 10 000 000 µs
● Individual updating
Set the period duration in the configuration parameters. Alternatively, execute an
individual updating via the control interface. MODE_SLOT must be deleted ("0" means
individual updating); LD_SLOT must be set to value 1 ("1" means period duration). Set
the period duration value in the field SLOT. The unit is always a microsecond.
– High-speed output activated: between 10 μs and 10 000 000 μs (10 s) in the
– High-speed output deactivated: between 100 μs and 10 000 000 μs (10 s) in the
– Standard output (100 Hz output): between 10 000 µs (10 ms) and 10 000 000 µs
The new period duration is applied at the next rising edge of the output.
