4-5 3-Point-A Verification Function
Timing Chart for Parallel Output
After reading the data, execute parallel output at the following timing:
The output form of OUT1 to 12 can be selected from bit, binary or BCD in the “Verification menu”
( Refer to 6-7)
➀......... Output ON time: Specify this in “Out ON time” in the I/O setting menu.
( Refer to 6-11) (It can be set between 10 ms and 2550 ms. The factory setting is
500 ms.)
➁......... Output delay time: Specify this in “Out Delay” in the I/O setting menu.
( Refer to 6-11) (It can be set between 0 ms and 255 ms. The factory setting is 5 ms.)
OUT1 to 12 • Only OUT9 to 12 are turned ON while waiting for the First reading.
Only OUT5 to 8 are turned ON while waiting for the Second reading.
Only OUT1 to 4 are turned ON while waiting for the Third reading.
• At Verify OK of the Third reading, outputs representing the matched record (Preset 1-
900) are turned ON.
(When the parallel output form is set to “Bit output”, OUT1 to 12 are turned OFF with
output numbers over 13. The factory setting is “Bit output”.)
• When Verify NG occurs, outputs representing “999” (NG and Verify NG) are turned ON.
• At Verify NG of the First reading, outputs representing “998” (Select Master NG) are
turned ON.
ALL outputs are turned OFF when Bit output format is selected (default).
• When a reading error occurs, outputs representing “997” (Read Error) are turned ON.
ALL outputs are turned OFF when Bit output format is selected (default).
OK Turns ON when Verify OK is output.
NG Turns ON at Verify NG and Select Master NG.
READ_ERR Turns ON when a reading error occurs (Only when the read error check is set).
