5.4.6. Download of parameter values at PLC start
NOTE
Please consider attentively this PLC behaviour.
During the initialisation process at the PLC start, B&R PLC downloads to the
encoder the parameter values that have been set next to the entries in the
Device Specific Parameters
group.
All values that are set in the
Init value
line of each parameter are sent to the
control node and overwrite the values currently saved.
To avoid transferring a value and overwriting the parameter stored in the
encoder memory, the
Init value
line under the entry in the
Device Specific
Parameters
group has to be kept blank.
In the example shown in Figure 18, the
Init
value
line is blank, thus it is not transferred to the encoder during the
initialisation process at the PLC start. The preset stored in the encoder memory
is preserved.
