(2) When the coincidence output function does not perform normal operation
(a) When Coincidence output 1 to 4 (RX10 to RX13) do not turn on
Check item
Are Coincidence output 1 to 4 assigned properly?
Are the comparison conditions for Coincidence output 1 to 4
proper?
Is Initial data setting request flag (RY9) or Setting change request
(Coincidence output 1 to 4) (RY14 to RY17) turned on after
changing Point setting (Coincidence output 1)/Lower limit value
setting (Coincidence output 1) (RWw0 to RWw1) to Upper limit
value setting (Coincidence output 4) (RWwE to RWwF)?
Is Reset command (Coincidence output 1 to 4) (RY10 to RY13) off?
(Only when Coincidence output is selected as the comparison
condition)
Are the settings in Point setting (Coincidence output 1)/Lower limit
value setting (Coincidence output 1) (RWw0 to RWw1) to Upper
limit value setting (Coincidence output 4) (RWwE to RWwF) within
the count range of the ring counter when the counter format is the
ring counter?
(b) When Coincidence output 1 to 4 (RX10 to RX13) does not turn off
Check item
Is the ON time of Reset command (Coincidence output 1 to 4)
*1
(RY10 to RY13) T
or longer? (Only when Coincidence output is
1
selected as the comparison condition)
For T
*1
, refer to the following.

(c) When only Coincidence output 1 to 4 terminals (EQU1 to EQU4) do not turn on
Check item
Is CH Coincidence output enable command (RY20, RY38) on
when Coincidence output enable command setting (address:
0106
) is set to By each channel (0)?
H
Is Enable command (Coincidence output 1 to 4) (RY18 to RY1B) on
when Coincidence output enable command setting (address:
0106
) is set to By each coincidence output (1)?
H
Is the external wiring to Coincidence output 1 to 4 terminals (EQU1
to EQU4) correct?
Action
Review the setting in Coincidence output channel assignment
setting (address: 0101
).
H
Review the setting in Coincidence output comparison condition
setting (address: 0102
).
H
Turn on Initial data setting request flag (RY9) or Setting change
request (Coincidence output 1 to 4) (RY14 to RY17) after changing
Point setting (Coincidence output 1)/Lower limit value setting
(Coincidence output 1) (RWw0 to RWw1) to Upper limit value setting
(Coincidence output 4) (RWwE to RWwF).
Turn off Reset command (Coincidence output 1 to 4) (RY10 to
RY13).
Set Point setting (Coincidence output 1)/Lower limit value setting
(Coincidence output 1) (RWw0 to RWw1) to Upper limit value setting
(Coincidence output 4) (RWwE to RWwF) within the count range of
the ring counter.
Action
Set the ON time of Reset command (Coincidence output 1 to 4)
*1
(RY10 to RY13) to T
or longer. ( Page 268, Appendix 1.2)
1
Action
Turn on CH Coincidence output enable command (RY20, RY38).
Turn on Enable command (Coincidence output 1 to 4) (RY18 to
RY1B).
Check the external wiring and correct errors.
