2. Terms and Definitions
Term Description/Definition
Protocol Macro This function enables data send/receive with general-
purpose external
devices by storing the data send/receive procedure (Protocol) used with
the general-purpose external devices in the Serial Communication Board
or Unit and executing the PMCR instruction in the CPU Unit.
Protocol The unit that comprises an independent communication processing for a
specific general-purpose external device as a data send/receive procedure
is called a “Protocol”. A “protocol” consists of two or more sequences.
Sequence
A unit of independent communication processing that can be activated
from the PMCR instruction on the ladder program. When activated, the
steps in the sequence are executed sequentially.
Step A unit to execute processing, which is send message, receive message,
send and receive message, clear receive buffer, or step queuing. Up to 15
steps can be set in a sequence.
Send Message A communication frame (command) sent to a general-purpose external
device. It is called from a step in a sequence and sent to a general-purpose
external device.
Receive Message A communication frame (response) sent from a general-purpose external
device. It is called from a step in a sequence and compared with data
received from the general-purpose external device.
Reception Matrix
A reception matrix is used when it is impossible to uniquely identify
communication frames (responses) sent from a general-purpose external
device. In a reception matrix, more than one communication frame can be
registered.
Case
A unit for registering multiple communication frames (responses) in a
reception matrix. One communication frame is registered as one case. Up
to 15 cases can be registered in a reception matrix.

* Hereinafter, the CX-Programmer Project File is called “project file”.
The user program in a project file is called “ladder program” or “program”.
The CX-Protocol Project File is called “protocol macro data”.
The purpose of this document is to describe the wiring methods, communication
settings, and setting procedures re
quired to establish a connection for
communications with applicable devices. In addition, the program used in th
is
document is designed to check that the connection has been correctly
performed (connection check). Since the program is not intended for perm
anent
use on-
site, full consideration is not given to functionality and performance.

6.3. Example of Connection Check for Communications
In this document, an example of sending and receiving messages between the controller and
the code reader using a ladder program and protocol macro data is given.
Between the PLC and the code reader, the “Execute Read (Sequence No. 900)” message is
sent and received. An overview of the sequence operation is shown below.
● Sequence Operation Overview
(1) In the ladder program, the PROTOCOL MACRO instruction (PMCR instruction) is
executed with sequence No. 900 of the protocol macro data specified.
(2) “Read trigger” command is selected from sequence No. 900 of the protocol macro data
and sent to the code reader.
(3) The code reader executes the command according to the data sent from the PLC.
(4) The PLC receives the execution result of the command from the code reader and stores
it in the specified memory address.
