Interpretation of the SLOT parameter value
The value written in the SLOT parameter is displayed as in the table below depending on the
LD_SLOT value and the mode is interpreted.
Valid modes for using the
SLOT value
1 Period duration PWM UDInt
Permissible value range*:
Minimum value: 10 µs, 100 µs or
10 000 µs (10 ms)
Maximum value: 10 000 000 µs (10 s)
* The permissible value range depends on the selected hardware output and sometimes on the high
-speed mode (high-
Individual updating of the parameter 'Period duration'
The following representation illustrates the workflow of the individual updating of the
parameter 'Period duration'. The described workflow principle can also be used on the
channels of the high-speed counters.
User writes the first parameter in SLOT and specifies the first parameter in LD_SLOT
Technology channel applies the first parameter and indicates the application by change in the bit STS_LD_SLOT
User writes the second parameter in SLOT and specifies the second parameter in LD_SLOT
Technology channel applies the second parameter and indicates the application by change in the bit
User writes 0 in LD_SLOT, (SLOT inactive)
Technology channels answers change in LD_SLOT with a change in STS_LD_SLOT
