Rung 2:8
Sequences through
block transfers
pre–selected by the
Data file #N21. The
sequencer is triggered
when the previous
block transfer has
completed or failed.
The sequence continues
until the module has
valid data.
Rung 2:9
Sequences through
block transfers
pre–selected by the
Data file #N22. The
sequencer is triggered
when the previous
block transfer has
completed or failed.
The sequence
continues until the
ladder is in the config
mode.
Rung 2:10
Performs block transfer
read of the factory
configuration
parameters.
