• This area is used for setting the comparison point (the value used to compare
with the present value) used for the coincidence output function.
• Setting procedure
1) Write any comparison point to the coincidence output No.1 point setting (Un\G
6 and 7).
Setting range: -2147483648 to 2147483647
2) Write "1" (Change request) to the coincidence output No.1 point change
request (Un\G10).
3) The comparison point written to the coincidence output No.1 point setting
(Un\G6 and 7) becomes effective, and the coincidence output No.1 point
change request (Un\G10) changes from "1" to "0" (No change request).
4) The comparison between the set comparison point and the present value is
executed.
• The above procedure is described as an example of the coincidence output No.1.
To set the coincidence output No.2, replace the coincidence output No.1 setting
(Un\G6 and 7) and the coincidence output No.1 point change request (Un\G10)
with the coincidence output No.2 point setting (Un\G8 and 9) and the coincidence
output No.2 point change request (Un\G11).

request (Un\G10)
• For details of the operation, refer to Section 5.3.1.
Note) If a value other than "1" is written to the coincidence output No.1 point
change request, the comparison point written to the coincidence output No.1
point setting does not become effective.
For the comparison point, a value previously set in the coincidence output
No.1 point setting is used.
For example, the default value of the coincidence output No.1 point setting is
"0". If "10000" is written to the coincidence output No.1 point setting, the
default value of "0" is used for the comparison point unless "1" is written to
the coincidence output No.1 point change request.
