Predefined Protocol Function; Communications Via Ethernet - Mitsubishi Electric L02SCPU User's Manual And Reference

3.37

Predefined Protocol Function

This function sends and receives packets predefined by using GX Works2, enabling easy communications with
external devices (such as measuring instruments and bar code readers).
Data are sent and received by registering the protocol setting data to the CPU module, and executing the program for
starting data communications. Use of the function helps to reduce the significant number of program steps since no
program is required to communicate with external devices.
In addition, the CPU module can send and receive data that vary in each communication as well as fixed data (such as
numerical values and codes) since devices can be included in the communication packets.
Remark
Before executing this function, check the version of the CPU module used. ( Page 376, Appendix 2)
