4.3.2 Coincidence output function
The coincidence output function compares the count value with a coincidence detection point or with an area divided
by the coincidence output upper/lower limit value.
The function then outputs the comparison result to Coincidence output 1 to 8 (X10 to X17) and coincidence output 1 to
8 terminals (EQU1 to EQU8)
Coincidence output means that the count value matches with the point or range specified by the user, then the result is
output to signals.
8 points are assigned to coincidence output, and each of them works individually for a different comparison/output
tasks.
Select a target channel in "Coincidence output (1 to 8) channel assignment setting" of the switch setting, and a
comparison condition in Coincidence output condition setting (Un\G0).
When the operation mode is set to a mode other than the normal mode, the setting configured to Coincidence output
condition setting (Un\G0) is ignored.
(1) Setting method of the coincidence output function
By selecting "Coincidence Output" as "Comparison output setting value" in the switch setting, the coincidence
output function operates.
Page 180, Section 6.2
(2) Comparison condition types and setting
Depending on the selected comparison condition, the range to be compared with the count value differs.
(a) Coincidence output
Coincidence output 1 (X10) turns on when the count value matches with a point set in Point setting
(coincidence output 1) (Un\G100, Un\G101)
(b) In-range output
Coincidence output 1 (X10) turns on when the count value is Lower limit value (coincidence output 1)
(Un\G120, Un\G121) or more and Upper limit value (coincidence output 1) (Un\G122, Un\G123) or less.
