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

Page 29

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.

Page 30

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.

Page 31

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.

Protocol Macro Section 1-6

1-6 Protocol Macro

1-6-1 Protocol Macro Outline

Protocol macro is a function that creates macros for communications protocols that conform to specifications for communications between general-purpose external devices that have a serial communications port.

Generally the protocol macro performs two kinds of function:

• Creation of communications frames (messages).

• Creation of procedures for sending and receiving communications frames (messages).

Creation of Communications Frames (Messages)

1,2,3... 1. Communications frames, referred to here as “messages” and which can be

understood by general-purpose external devices, can be created according to the communications specifications.

Header Address Data Check

code

Terminator

Note In general, the data area of a send message contains a command code and

data. The data area of a receive message contains a response code.

2. Variables for reading data from (or writing data to, if receiving) the I/O memory (data memory, for example) of the CPU Unit, can be integrated into the messages.

I/O memory

Read

Send

Variable R ( )

Variable W ( )

Receive

Write

I/O memory

This function has the following advantages:

• Ladder program processing will not be necessary at the CPU Unit when, for example, sending messages after arranging them all in data memory.

CPU Unit

Not necessary

Header

Address

Send

Page 40

Protocol Macro Section 1-6

• The components of the previously created messages are stored in memory at the PMSU, not the CPU Unit. When sending or receiving data, the CPU Unit only has to execute the PMCR instruction.

CPU Unit

PMCR instruction

• When handling one part of the I/O memory data, if the variable required for reading that data has been integrated into a send message, the PMSU will automatically read the required data from the I/O memory of the CPU Unit when the PMSU sends the message. Similarly, when writing data from one part of a received message into I/O memory, if the variable required to read the data has been integrated into the reception settings message, the PMSU will automatically write the data at the designated position in the message into I/O memory when the PMSU receives the message.

Creating Procedures for Sending and Receiving Communications Frames (Messages)

1,2,3... 1. This function enables all the processing needed to send or receive a mes-

sage to be handled as one step, and possesses all the commands (step commands), such as Send, Receive, Send&Receive and Wait, that are needed for each step.

2. A receive message created with protocol macro will set an expected message for comparison with messages that are actually received.

Protocol Macro Structure Section 1-7

1-6-2 Standard System Protocol

Data exchange protocols (called standard system protocols) for OMRON Units (Temperature Controllers, Panel Meters, Bar Code Readers, Modems, etc.) have been installed into the PMSU. By setting the prescribed receive/ send data and executing the PMCR instruction, therefore, data exchange can be easily performed with OMRON Units.

1-7 Protocol Macro Structure

The protocol consists of a communications sequence (“sequence” in short), which is an independent process for the general-purpose external device (for example, reading a process variable from a Temperature Controller). One sequence consists composed of some steps, each of which is composed of a Send, Receive, or Send&Receive command, send/receive message, branch or end according to the result of the process.

For example, the sequence to read a process value from the temperature controller sends to the controller a send message (a string containing the read command with a header, address, check code, and terminator), and then receives a receive message (a string containing a response to the read command with a header, address, check code, and terminator).

The sequence determines, according to the result of process, whether to send the same send message again (called retry) or execute the next process (reading process value from the Temperature Controller linked to another address, etc.), for example.

Protocol Macro Structure Section 1-7

1-7-1 Step Structure

Each step has the fixed processing framework as follows. Users create protocols by setting parameters for each framework.

One step contains one command (Send, Receive, Send&Receive, Wait, Flush, Open, or Close) and one or two messages (send, receive, or send/ receive). The step changes from one to another by the Next Process within the step.

(There are 12 types for the Communications Board of the C200HX/HG/HE because it does not support CompoWay/F.) The protocols can be displayed by selecting the System Tab of the project workspace.

Note To transfer standard system protocols to the PMSU or create a new protocol

The standard system protocols have been installed into the PMSU at our factory.

Protocol Macro Outline Section 3-1

3-1 Protocol Macro Outline

The Protocol Support Tool allows users to freely create and edit protocols, which are procedures for sending data to and receiving data from generalpurpose devices connected to the PMSU (see note) through RS-232C or RS422A/485. The protocol macro is a function to implement the sending and the receiving messages by the execution of a starting instruction for the protocol macro (PMCR instruction) of the CPU Unit’s user program.

For CJ2 CPU Units, the PMCR2 instruction can be used in addition to the PMCR instruction. For details of the PMCR and PMCR2 instructions for CS/ CJ-series Units, refer to the SYSMAC CS/CJ-Series Programmable Control- lers Instructions Reference Manual (W474). For details of the PMCR instructions for SYSMAC Alpha-Series (C200HX/HG/HE) Units, refer to the

Programmable Controllers C200HX/HG/HE-CPU

(W322).

3-1-1 Sequence/Step Structure

One sequence consists of up to 16 steps. One step includes one command (Send, Receive, Send&Receive, Open, Close, Flush, or Wait (for CS/CJ only)) and one or two messages (Send, Receive, or Send&Receive). Step transition is designated by the “next process/error process” within the step.

Half-duplex: Receives when not performing send process. Full-duplex: Receives throughout execution of the sequence.

Internal process Buffer

Send Following send process (Send command,

Send&Receive command), data from I/O memory is converted under the designated conversion formula and the send message is assembled and is transferred to the send buffer.

Receive Following receive process (Receive

command, Send&Receive command):

1. The data in the receive buffer is input, comparison with the expected message is executed, and switching of the next process takes place.

2. If there is a Response Write, the data will be written to I/O memory after being converted with the designated conversion formula.

To transmission line

From transmission line

The send message moves to the transmission line via the send buffer.

Half-duplex: Data that is received from the transmission line when send process is not being performed will be saved in the receive buffer. Full-duplex: All data received from the transmission line during sequence execution will be saved in the receive buffer.

Data (Address) (Repeat counter)

If the Send command (or the Send&Receive command) is executed with a certain step, the send message set by that step will be assembled and sent from the send buffer as shown below. If a variable (reading variable) has been integrated into the send message, the appropriate data will be read from I/O memory and converted to the designated form according to the variable, and the send message will be assembled.

Note When a send completion monitoring time has been set for send process and

the time is exceeded without sending a message, the step will end abnormally and the system will move to the error process. Otherwise, the step will end normally and move to the next process.

Receive Process (Receive Command, Send & Receive Command)

If, with a certain step, the Receive command (or the Send&Receive Command) is executed, the data will be taken out of the receive buffer and a comparison with the expected message will be made. If the data does not correspond, the step will end abnormally and the system will move to the error process. If the data does correspond and a variable (write variable) has been integrated into the expected message, it will be converted to the format designated by the variable, and write process to I/O memory in the CPU Unit will be performed. All processing for the step will be completed and the system will move to the next process.

Note: The Write Timing will depend on the setting for the response type (scan mode, interrupt mode) in sequence attributes only if With/Without Response Writing is set to Yes in the step attributes when the operands are set.

4. Notification to the CPU Unit: Completion of the sequence and Write notified by the Protocol Macro Execution Flag.

Note: When the operands are set and the response type is set to interrupt mode in sequence attributes, designation will be possible with the interrupt process.

Send & Receive Process (Send & Receive Command)

Clear Process (Flush Command) for Receive Buffer (CS/CJ only)

The receive (Receive) process will start approximately 60 µs after the send process is completed.

In general, when communications commands are sent as send messages and responses are received as receive messages, Send&Receive will be executed.

Note With the CS/CJ, there is a time-lag after send operations for the half-duplex

(refer to page 80).

By executing the Flush command, all the data in the receive buffer is cleared. For example, this is used in the full-duplex mode before executing the receive process, to clear data left in the receive buffer because of noise.

This command can also be used, for example, in full-duplex mode when a communications error occurs. Without aborting, switch the step in Goto, execute the Flush command in the step, clear the receive buffer, and retry.

Integration of Variables One of the characteristics of sending and receiving data with the protocol

macro function is the way that instructions (variables) for reading from and writing to I/O memory in the CPU Unit can be integrated in the send and receive messages themselves.

To designate which area of I/O memory is used for creating send messages and which area of I/O memory is used for storing receive messages, the following three methods can be used.

1,2,3... 1. Operand Designation: Use the designated memory address with the oper-

ands for the PMCR instruction.

2. Direct Designation: Directly designate the I/O memory address.

3. Link Word Designation: Use the shared data area (link word) between the CPU Unit and the PMSU.

Page 100

Protocol Macro Outline Section 3-1

Designation Methods for Send/Receive Data Area

Designation

method

Operand designation (set within send/ receive message)

Direct designation (set within send/ receive message)

Link word designation (set with sequence attributes)

The I/O memory area is designated using the third (first word of send data storage area) and fourth (first word of receive data storage area) operands (second and third operands for C200HX/HG/HE) in the PMCR instruction of a ladder program within the send/receive message. Sending and receiving will be carried out using the designated I/O memory area. It is possible to set the system to either write or not write the receive data in the buffer area (having been converted under the designated conversion method) after each step using the With/Without Response Writing setting for step attributes. When the receive process is executed following a step command which has been set to With Response Write, the receive data in the receive buffer will generally be written to the CPU Unit’s I/O memory in one of the two ways shown below. (Set with the response type for sequence attributes. For details refer to page 87.)

1.Scan notification mode: With each CPU Unit scan, receive data is written to I/O memory. Since the CPU Unit refreshes with each scan, writing to the I/O memory area will not take place simultaneously with receive process and there will be a time-lag.

2. Interrupt notification mode: When data is received, an interrupt is executed at the CPU Unit and the receive data is immediately written to the designated I/O memory area. (Either the fixed number or the receive case number are possible for the interrupt program number) Note: After the sequence has been completed, the data in the receive buffer will be read to I/O memory by the scan notification method.

The I/O memory address is set directly, in the send/receive message. Since the CPU Unit refreshes with each scan, writing to the I/O memory area will not take place simultaneously with receive process and there will be a time-lag.

A holding data shared area is designated for the CPU Unit and the PMSU. It is possible to set two link words, 1 and 2. Link word 1: IN (receive data storage)

Link word 2: IN (receive data storage)

Designations are made under the I1, I2, l3, and l4. Since the CPU Unit refreshes with each scan, writing to the I/O memory area will not take place simultaneously with receive process and there will be a time-lag.

I1 (IN for link word 1) O1 (OUT for link word 1) I2 (IN for link word 2) O2 (OUT for link word 2)

OUT (send data storage)

Application

With a PMCR instruction in a ladder program, the data area that is jointly used for the sequence can be set automatically. Using the interrupt function, high-response processing can be achieved.

Set when allocating a fixed data area and used separately within the step. When changing, it will be necessary to correct the step and resend.

Note 1. CS/CJ only.

2. C200HX/HG/HE only.
