4.3 Comparison Output Function 4.3.2 Coincidence output function
(4) Output destination of comparison result for the coincidence output function
The following table shows the output destination of comparison result for each comparison condition.
(5) Output setting on coincidence output 1 to 8 terminals (EQU1 to EQU8)
In order to output signals from coincidence output 1 to 8 terminals (EQU1 to EQU8) to outside, enable output by
turning on CH1 Coincidence output enable command (Y02). Doing so enable all coincidence output assigned to
the target channel in "Coincidence output (1 to 8) channel assignment setting".
The initial value of Coincidence output condition setting (Un\G0) is all 0000
H
(all coincidence output) right after the CPU
module is powered on or reset. Also, the initial value of Point setting (coincidence output 1 to 8) (Un\G100 to Un\G115) and
CH1 Present value (Un\G1050 to Un\G1051) are 0. Therefore, Coincidence output 1 to 8 (X10 to X17) turn on.
When CH1 Coincidence output enable command (Y02) is turned on, signals are output as if coincidence output was
detected.
In order to prevent the condition above, take one of the following measures before turning on CH1 Coincidence output
enable command (Y02).
● Measure 1
When using only coincidence output as the comparison condition, and besides when not using Operating condition
settings batch-change command (Y01) or the parameter settings of the programming tool, set a different value for CH1
Present value (Un\G1050 to Un\G1051) and Point setting (coincidence output 1 to 8) (Un\G100 to Un\G115) by one of the
methods below. Then switch Reset command (coincidence output 1 to 8) (Y10 to Y17) as follows; OFF, ON, then OFF.
• Change Point setting (coincidence output 1 to 8) (Un\G100 to Un\G115), and reflect the change by Setting change
request (coincidence output 1 to 8) (Un\G180 to Un\G187).
• Change CH1 Present value (Un\G1050, Un\G1051) by the preset/replace function.
• Change CH1 Present value (Un\G1050, Un\G1051) by start counting.
● Measure 2
When using in-range output or not-in-range output as the comparison condition, or when using Operating condition
settings batch-change command (Y01) or the parameter setting of the programming tool, configure related settings in
Page 110, Section 4.3.2 (3) by one of the methods below.
• Set them by the sequence program, and switch Operating condition settings batch-change command (Y01) as
follows; OFF, ON, then OFF.
• Write the parameter settings into the CPU module from the programming tool, and reflect the settings by switching
the CPU module as follow; STOP, RUN, STOP, and RUN.
