Timing Chart for Parallel Output

Parallel output is executed at the timing shown below, which is based on the read data for verifica-
tion.
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

• 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, 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.)

• At Verify NG, outputs representing “999” (NG and Verify NG) are turned ON.

• If Verify NG is output at 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).
