6. HOW TO COMMUNICATE WITH ID TAGS
Chapter 6 HOW TO COMMUNICATE WITH ID TAGS
The following describes the programming method for communicating with ID tags using
instructions.
When utilizing the program examples introduced in this chapter into an actual system,
be sure to fully verify that control in the target system will be unproblematic.
6.1 Programming Precautions
The following describes the precautions and the like that you need to know before
using the RFID interface module to create a program for communicating with ID tags.
(1) Executing instructions on each channel
Multiple instructions cannot be executed simultaneously on a single channel.
Be sure to create an interlock in the program to ensure that multiple instructions are
not executed on one channel.
Simultaneous execution on different channels (channel 1 and channel 2) is possible
with EQ-V680D2.
(2) Initial value of buffer memory
When the initial value of buffer memory needs to be changed to communicate with
ID tags, a sequence program for changing the value needs to be incorporated.
