Figure 9.3.3B is an example of a controlled PLC flag read and write.
The 16 PLC coils starting at address 33 will be written to and read from
the PLC during controller scans when the =1G--01/C register is at 100%
of scale. The data written to the PLC will be the u ser flags of register
=1G--01/C.u.a to =1G--01/C.u.p. The data read will be available to any
block link to this PLCB block. T he 16 PLC coils starting at address 33
will not be written to or read from the PLC when =1G--01/C register is at
0% of scale. T his allows the controller configuration to control when this
PLC register is written to. The =1G--01/C register needs to have a value
of 100% of scale for a minimum of two seconds for the controller to
write and read the value from the PLC.

Figure 9.3.3B. Controlled PLC Flag Read and Write
Figure 9.3.3C is an example of a controlled PLC r egister read. The PLC
register at address 40004 will be read from the PLC during controller
scans when user flag p of =1G--01/D is on (=1G--01/D.u.p). The PLC
register at address 40004 will not be read from the PLC when user flag
p of =1G--01/D is off. T his allows the controller configuration to control
when this PLC register is read. T he user flag p of =1G--01/D needs to
be on for a minimum of two seconds for the controller to read the value
from the PLC.
