Description
Turned on if the counter value is greater than the set
value No. 1.
Latched on if the counter value is equal to the set value
No. 1 turned off by the coincidence signal reset
command.
Turned on when the counter value is less than the set
value No. 1.
Latched on when the preset request is given from
external input. Turned off by the external preset
detection reset command.
Turned on if the counter value is greater than the set
value No. 2.
Latched on if the counter value is equal to the set value
No. 2 turned off by the coincidence signal reset
command.
Turned on when the counter value is less than the set
value No. 2.
Unusable
Turned on on completion of the preset function
executed when the preset command
{(RY(n+1)1(RY(n+1)8)} turns on.
Turned off when the preset command switches from ON
to OFF.
Turned on at counter function start (execution) when the
counter function selection start command
{(RY(n+1)6(RY(n+1)D)} turns on.
Turned off when the counter function selection start
command switches from ON to OFF.
Unusable
Turned on by the high-speed counter module to request
initial data setting after power-on or hardware reset.
Turned off on initial data processing completion (when
initial data processing completion flag (RY(N+7)8) turns
on).
Unusable
Turned on when the high-speed counter module is in
the ready state on completion of initial data setting after
power-on or hardware reset.
Unusable
n: Address assigned to the master station by station number setting.
