3.3 Programmable Controller CPU IO Signals
3.3.1 IO signal list
The following provides a list of the IO signals of the RFID interface module.
Note that the IO numbers (X/Y) shown hereafter indicate the number when the first IO
number of the RFID interface module is set to 0.

*1. Effective only with EQ-V680D2 use.
*2. Available for use only when both the “test mode enable” bit and “Y contact test
request enable” bit are set to “0” (enable) on switch 2 of the intelligent function
module switch. (Refer to Section 4.7)
Point
Use-prohibited IO signals are used by the system and cannot be used by users. In
the unlikely event that a use-prohibited IO signal is turned ON/OFF by a sequence
program, the functions of the RFID interface module cannot be guaranteed.
