CC-Link
Link number Signal name Description
RX(n+1)8 Initial data proces-
sing request flag
After the power is turned on or after the hardware
reset, the initial data processing request flag is
turned on by the CC-Link Coupler 750-310 in order
to request the initial data setting. It is turned off
when the initial data setting is complete (i.e. initial
data processing complete flag RY(n+l )8 is turned
on).
RX(n+1)9 Initial data setting
complete flag
When there is an initial data setting request (i.e.
RY(n+l)9 is turned on), it is turned on by the initial
data setting completion. When the initial data setting
request flag is turned off after the initial data setting
completion, the initial data setting complete flag is
also turned off.
RX(n+1)A Error status flag This is turned on when an error occurs on the CC-
Link Coupler 750-310.
RX(n+1)B Remote READY This is turned on when the initial data setting is
complete and the CC-Link Coupler 750-310 is in the
READY status, after the power is turned on or after
the hardware reset. It is turned off during the test
mode, (This is used to interlock the read and write
from the master module,).
RY(n+1)8 Initial data proces-
sing complete flag
After the power is turned on or after the hardware
reset, the initial data processing complete processing
is executed by the initial data processing request,
and this flag is flag turned on after the processing is
completed.
RY(n+1)9 Initial data proces-
sing request flag
Turn this on to set or modify the initial data.
