Chapter 11 Data Communications Using The Predefined Protocol - Mitsubishi Electric QJ71E71-100 User Manual

CHAPTER 11
Data can be transferred between a connected device and the CPU module with a protocol appropriate to the
connected device (such as a measuring instrument or a bar code reader).
Device or buffer memory data can be taken into communication packets, and thereby this protocol communications are
suitable for data that may change in each communication.
The protocol setting required to communicate with the connected device can be configured in GX Works2.
Protocols can be selected from the Predefined Protocol Library or can be created and edited.
This function is available only in the QJ71E71-100 with the serial number (first five digits) of "15042" or later.
