SECTION 1
Introduction

Overview of the CX-Protocol Section 1-1
1-1 Overview of the CX-Protocol
The CX-Protocol is the software for creating a procedure (or protocol) for
sending or receiving data to or from general-purpose external devices connected to a Protocol Macro Support Unit (PMSU) through RS-232C or RS485A/422.
A protocol consists of a set of communications sequences. CX-Protocol transfers a protocol to the PMSU, specifies the sequence number of the protocol
using the PMCR instruction on the CPU Unit, and executes the communications sequence.
The communications sequence consists of several steps and allows the user
to iterate, branch, or end these steps according to the result of the process.
Note 1. In the following section, the Communications Board for the C200HX/HG/
HE, Serial Communications Board for the CS and CQM1H, and Serial
Communications Units for the CS/CJ are referred to as the “PMSU.”
2. The CJ-series protocol macro function of the CJ-series Serial Communications Unit is used even for the system configuration described below,
which uses a CP-series CPU Unit with a CJ-series Serial Communications
Unit. The CJ Series is thus specified in descriptions unless there is information unique to the CP Series.

1-2-1 Features of the Protocol Macro Function
Support for a wide range of communications protocols
Supports communications with almost all external general-purpose devices
that have RS-232C or RS-422A/485 ports and support half-duplex or fullduplex mode (full-duplex is for CS/CJ only) and start-stop synchronization

Fe atu re s Section 1-2
mode (refer to 4-1 Applicable Range of the Protocol Macro Function for
restrictions).
Creation of send frames and receive (expected) frames according to the desired communications
frame specifications
Enables creation of almost all send frames (frames composed of commands,
data, and so on) and receive (expected) frames (frames composed of
responses and so on) according to the communications frame (message)
specifications of external devices.
Support for operation functions relating to communications
Supports error check code calculation, frame length calculation during transmission process, and numeral data conversion between ASCII and hexadecimal.
Support for the send and receive time monitoring function
Supports the receive wait monitoring, receive finish monitoring, and send finish monitoring functions. This function lets you designate whether to finish
send/receive process or to start retry process when those monitoring times
are exceeded.
Support for retry process Lets you designate, only by designating the number of retries, whether to
automatically execute send/receive retries when an error occurs.
Integration of variables for read/write process with PLC into send frames and receive (expected)
frames
Enables integration of variables for read process from PLC’s I/O memory into
send frames (messages) themselves. Data in the PLC that has been read
during transmission process can be used for addresses (destinations) or data.
This function also enables integration of variables for write process to PLC’s I/
O memory into receive frames (messages) themselves. Addresses (destinations) or data can be written into the PLC during the receive process.
Easy realization of rich functions including 1:N communications and switching data write destinations,
using repetition variables
Lets you designate repeat variables for send/receive process (repeat counter)
in variables. With this function, a wide variety of process can be easily realized: for example, sending the same data to multiple addresses (destinations)
by switching them during 1:N communications; switching write destination
addresses in PLC’s I/O memory during data receive process.
Execute interrupt program on the PLC while receiving data
Enables interrupt program execution on the PLC (CPU Unit) while receiving
data. The interrupt function is supported only by the Communications Board
for the C200HX/HG/HE and Serial Communications Board for the CS. It cannot be used with the Serial Communications Unit for the CS/CJ.
Switch the next process depending on the received data
The next process can be switched according to the data comparison with the
data registered to the maximum of 15 types.
The following functions have been added to the protocol macro for the CS/CJ.
Error check code (only for the CS/CJ protocol macro)
LRC2 (2’s complement of LRC) and SUM1 (1’s complement of SUM) have
been added to the error check codes.

Features Section 1-2
Wait command to keep the next process on standby until a synchronous signal is input from the PLC
(only for the CS/CJ protocol macro)
During the send/receive sequence step, the next process can be kept on
standby until a synchronous signal is input from the PLC (CPU Unit). This
enables computation processing such as data processing on the CPU Unit
during the send/receive sequence.
Supports half-duplex and full-duplex transmission mode (only for the CS/CJ protocol macro)
The conventional protocol macro provides only the half-duplex macro. With
the half-duplex macro, the receive buffer is cleared right after the send operation, thus the received data cannot be used. With the full-duplex mode, all the
data received within the sequence can be used and data can be sent and
received at the same time.
Note The full-duplex mode can be used with the RS-232C or four-wire setting. It
cannot be used with the 1:N or two-wire setting. (Only for models with the RS422A/485.)
Clear data using Flush command within the receive buffer at any time (only for the CS/CJ protocol
macro)
With the full-duplex mode, the receive buffer is cleared only right before executing the send/receive sequence. If any reception error occurs, the received
data can be cleared at any time using the Flush command (receive buffer
clear).
Turn the DTR control signal ON and OFF using the Open/Close command (only for the CS/CJ protocol
macro)
When connected to a modem device, DTR signal is used to indicate that the
Serial Communications Board or Unit (DTE) is ready to send or receive data.
Previously, the DTR signal could be turned ON only during the send/receive
sequence.
Now the DTR signal can be turned ON or OFF at any time within the send/
receive sequence. This allows connection or disconnection with a modem
using the protocol macro.
The DTR signal can be set to ON even after the send/receive sequence has
completed. The DTR signal can be retained even after changing to another
protocol mode (for example, host link).
With this function, remote programming or monitoring can be performed
through a remote Programming Device by changing to the host link mode
using the STUP instruction after connecting to a modem.
1-2-2 Features of the CX-Protocol
Simultaneous display of tree (hierarchical) view and list (table) view
The CX-Protocol displays data in the form of a tree in the left pane, which
gives you easier understanding of the hierarchical structure of data you are
setting/monitoring.
Object-oriented operation Double-clicking target data, instead of choosing from menus, opens its corre-
sponding pop-up dialog, which enables you to create protocols quickly without
a thorough understanding of operation menus.
Supplied standard system protocols
Data exchange protocols for OMRON’s components (Temperature Controllers, Panel Meters, Bar Code Readers, Modems, and so on) are included as
standard system protocols.
Notice that those standard system protocols are included also in the PMSU.

Checking the Contents of the Package Section 1-3
Possible to trace send/receive message
By executing the trace function from the CX-Protocol, the PMSU can trace
and save chronological data of send/receive messages up to 670 bytes for the
C200HX/HG/HE and up to 1,700 bytes for the CS/CJ. Each data item can be
displayed and printed for reading and saved as a trace file.
