Send/receive Data Monitoring Function

Overview

The send/receive data monitoring function is a function to monitor send/receive data between the C24 and a target device on
communication lines.
The system startup phase can be shortened by analyzing the send/receive data on the communication lines when debugging
the program.
The two methods below are available for the send/receive data monitoring method.
This chapter explains the send/receive data monitoring by the program.
Send/receive data monitoring by program
Monitoring is performed by writing the monitor start instruction to the send/receive data monitoring designation area of the
buffer memory.
Send/receive data monitoring by Engineering tool
Monitoring (circuit trace) is performed by using the circuit trace function of Engineering tool ( Page 109 Circuit Trace).
