7 DATA COMMUNICATION USING THE BIDIRECTIONAL PROTOCOL

7 DATA COMMUNICATION USING THE BIDIRECTIONAL PROTOCOL

Data communication using the bidirectional protocol is a function for sending/receiving
any data using the message format and transmission control procedure for the Q
series C24 bidirectional protocol between external devices and programmable
controller CPUs.
Any external devices that can install application programs and transmit and receive
data in accordance with the MELSEC programmable controller protocol can
communicate with the programmable controller CPUs using the bidirectional protocol.

This chapter explains the basic transmission and reception methods when performing
data communication using the bidirectional protocol.
Follow the procedure described in this chapter to create sequence programs for
sending and receiving data for the programmable controller CPU.
Regarding the additional functions listed below for data communication using the
bidirectional protocol, see the separate User's Manuals (Application)

• Reading receive data using interrupt programs
• Sending/receiving data using ASCII data (ASCII-BIN conversion)
• Sending/receiving data using transparent code designation
