The following describes in detail the input/output signals of the RFID interface module.
(1) Input signals
(1) Turns ON when the RFID interface module is ready after programmable controller
CPU power ON or reset.
(2) Turns OFF when an RFID interface module hardware error occurs.
(1) Turns ON when the communication processing with all ID tags is completed when
the communication specification is multi-trigger.
(2) Turns ON when RFID interface module communication is suspended due to the
elapse of the auto command wait time when the communication specification is
repeat auto, FIFO repeat, or multi-repeat.
Turns ON when communication is suspended due to antenna disconnection when
the communication specification is repeat auto, FIFO repeat, multi-trigger, or
multi-repeat.
(3) Turns OFF when the ID command execution request (Y14, Y1C) is turned OFF.
(4) The timing chart is as follows:
1) ID communication complete (X2, XA) turns ON when the communication
specification is Multi-trigger and the last communication is completed.
Turns ON when communication is suspended due to the elapse of the auto
command wait time when the communication specification is repeat auto, FIFO
repeat, or multi-repeat.
Turns ON when communication is suspended due to antenna disconnection
when the communication specification is repeat auto, FIFO repeat, multi-trigger,
or multi-repeat.
2) The ID command execution request (Y14, Y1C) turns OFF when ID
communication complete (X2, XA) turns ON.
3) ID communication complete (X2, XA) and ID-BUSY (X3, XB) turn OFF
when the ID command execution request (Y14, Y1C) turns OFF.
