6. HOW TO COMMUNICATE WITH ID TAGS
6.6 For Use in Remote I/O Network
6.6.1 Sample program for use in remote I/O Network
This sentence is explanation of the usage of the RFID module on the MELSECNET/H
remote I/O network.
Point
The dedicated instructions used for reading/writing the buffer memory of the
intelligent function module on a remote I/O station (REMTO and REMFR) are the
execution type for which several scans are needed. Therefore, transmissions of the
execution results are not synchronized with the I/O signal operations.
When control the output device after reading/writing the buffer memory of the
intelligent function module, put an interlock circuit which controls an output device
after the completion device of the dedicated instructions turn on by all means.
