CHAPTER 4 FUNCTION

4.3 Comparison Output Function
4.3.2 Coincidence output function
(c) Operation example of not-in-range output
The following figure shows an operation example when not-in-range output is set as the comparison condition.
Note that the coincidence output 1 is assigned to CH1.
Coincidence output 1 to 8 (X10 to X17) turn on regardless of CH1 Coincidence output enable command (Y02).
Even if Upper/lower limit values (coincidence output 1 to 8) (Un\G120 to Un\G151) are changed, the count value is not
compared with the changed value when Setting change request (coincidence output 1 to 8) (Un\G180 to Un\G187) is not
set to Requested (1
H
).
Number Description
1)
Start comparison of the count value and values set to Lower limit value (coincidence output 1) (Un\G120, Un\G121) and Upper
limit value (coincidence output 1) (Un\G122, Un\G123) in the following order.
(1) Write 1000 into Lower limit value (coincidence output 1) (Un\G120, Un\G121).
(2) Write 2000 into Upper limit value (coincidence output 1) (Un\G122, Un\G123).
(3) Write Requested (1
H
) into Setting change request (coincidence output 1) (Un\G180).
(4) The setting value of (1) and (2) is reflected at the time when Setting change request (coincidence output 1) (Un\G180) is
automatically reset from Requested (1
H
) to Not requested (0
H
) by the QD65PD2.
2)
When CH1 Present value (Un\G1050, Un\G1051) < Lower limit value (coincidence output 1) (Un\G120, Un\G121) is made,
Coincidence output 1 (X10) turns on since the present value is outside the specified range.
3)
To output signals from the coincidence output 1 terminal (EQU1), turn on CH1 Coincidence output enable command (Y02).
In this case, the coincidence output 1 terminal turns on immediately since Coincidence output 1 (X10) is already on.
4)
When CH1 Present value (Un\G1050, Un\G1051) Lower limit value (coincidence output 1) (Un\G120, Un\G121) is made,
Coincidence output 1 (X10) and the coincidence output 1 terminal (EQU1) turn off since the present value is within the
specified range.
5)
When CH1 Present value (Un\G1050, Un\G1051) > Upper limit value (coincidence output 1) (Un\G122, Un\G123) is made,
Coincidence output 1 (X10) and the coincidence output 1 terminal (EQU1) turn on since the present value is outside the
specified range.
