2. Terms and Definitions
Term Explanation and Definition
protocol macro A data transfer procedure (protocol) with a general-purpose external
device is created and stored in a Serial Communications Board or a Serial
Communications Unit. This functional protocol enables data to be
exchanged with general-purpose external devices by executing the
protocol macro instruction (hereinafter ref erred to as "PMCR instruction")
protocol A set of rules governing the data transfer procedures that gather
independent communication processing wit h a specific general-purpose
sequence A unit of action to perform the independent communication processing that
can be started by executing the PMCR instruction in a program.
A sequence that is started by the instruction executes steps registered in
its own sequence.
step A unit to execute any one of the followings: message send processing,
message receive processing, message send/ receive processing, receive
send message A communications frame (command) sent to a general-purpose external
device. A send message is invoked by steps in a sequence and is sent to a
receive message A communications frame (response) sent from a general-purpose external
device. A receive message is invoked by steps in the sequence and is
compared with data received from general-purp ose external devices.
matrix A function to register and use some communications frames (responses)
when more than one communications frame is expected to be received
from a general-purpose external device.
The receive processing can be executed according to registered
communications frames by using this funct ion.
case A unit to register multiple communications frames (response) to a matrix.
One communications frame is registered as one case.
Up to 15 types of cases can be registered per matrix.

Additional Information
9. Program
This section describes the details on the program used in this guide.
9.1. Overview
The following explains the specificat i ons and functions of the program that are used to check
the connection between the Digital Temperature Controller (hereinafter referred to as the
"Destination Device") and the PLC (Serial Communications Unit (hereinafter referred to as the
"SCU")).
This program uses the protocol macro function of the SCU, to send/receive the "Properties
Read" command to/from the Destination Device and detect a normal end or an error end.
A normal end of the send/receive processing means a normal end of the communications
sequence.
An error end means an error end of the communications sequence and an error of the
Destination Device (identified in the response data from the Destination Device)
Here, the prefix "&" is added to decimal dat a and the prefix "#" is added to hexadec imal data
when it is necessary to distinguish between decimal and hexad ecimal data. (e.g. , "&1000 " for
decimal data and "#03E8" for hexadecimal data)
OMRON has confirmed that normal communic ations can be performed using this program
under the conditions of 5.2. Device Configuration. However, we do not guarantee the normal
operation under disturbances such as electri cal noise or device performance variation.

With this program, the error detection processing is performed according to the following
descriptions (1) to (3). For information on error codes, refer to 9.8. Error Processing.
(1)Errors at the execution of the PMCR instruction (PMCR instruction errors)
An incorrect communications sequence number and an incorrect memory address, both of
which prevent the execution of the PMCR instruc tion, are detected as PMCR instruction
errors. If an error occurs, the error code (1519.00 to 03) wil l be generated to identify the
error, which indicates the port operating status in the CIO area allocated to the SCU.
(2)Errors in communications with the Desti nation Device (Communications error)
Errors that occur in communications with the Des tination Device, such as character
corruption and transmission errors caused by unmatched baud rate setting, are detected as
communications errors. If an error occurs, the Sequence Abort End Completion flag
(1519.10) in the CIO area allocated to the SCU will be turned ON to identify the error.
(3)Errors in the Destination Device (Destinat i on Device errors)
Destination Device errors include a command err or, a parameter error, a data error and an
execution failure in the Destination Device. An error is identified in the response data that is
returned from the Destination Device. Wit h this program, an error can be detected by
