About Communications Methods

Chapter

Introduction

This chapter briefly describes the supported communications methods and how to wire equipment. First-time users must read this chapter to ensure proper installation of the equipment.

The programs for the communications functions are created on the host device (PLC or computer), and the 900-TCx's parameters are monitored or set from the host PLC or computer. Therefore, the description provided here is from the viewpoint of the host device.

All Bulletin 900 Temperature Controllers offer an ASCII communications protocol format based on CompoWay/F for general serial communications. This format uses a standard frame format. Therefore, it can simplify communications between 900-TCx components and the host device.

The 900-TC8, 900-TC16, and 900-TC32 controllers also have Modbus® communication protocol. Modbus is a standard communications control method that conforms to the Modicon Company’s RTU-mode Modbus protocol (PI-MBUS-300 Revision J). It supports functions equivalent to the CompoWay/F Read Variable Area, Write Variable Area, Operation Command, and Echoback Test functions.

Simplified communications can include:

• Reading/writing of parameters

• Operation instructions

• Selection of setup levels

Communications are subject to the following condition:

• Parameters can be written only when the Communications writing

parameter is set to ON (enabled).

Modbus is a registered trademark of Schneider Electric

Note: Highlighted characters in the table above indicate defaults. ➊ Direct RS-232C communication is only available with the 900-TC8. However, the 900-CONVx25(B) RS232/USB

to RS485 converter can be used for 900-TC16 and 900-TC32 controllers.

➋ Communications speed, data bits, stop bits and vertical parity can each be configured independently in the

controller’s Communications Setting function group.

➌ 900-TC8, 900-TC16, and 900-TC32 Series B controllers only. ➍ The communications data length for Modbus must be 8 bits.

When the host device transmits a command frame, the 900-TCx transmits a response frame that corresponds to the command frame. A single response frame is returned for each command frame. The following diagram shows the operation of the command and response frames.

Communication Parameters

Note that communications parameters are enabled after they have been changed by resetting the controller.

• Protocol Selection (

psel)

The communications protocol can be selected. Set CompoWay/F (900-TC) or Modbus.

• Communications unit number (

u-no )

This parameter is for setting a unique unit number for each of the temperature controllers in the system. This unit number is set so that the host device can identify the temperature controller when communications are carried out with the host device. Set a unit number within the range 0 to 99 for each temperature controller connected to the host device on the network. Default is “1”. When two or more temperature controllers are used, do not set them to the same unit number Doing so will prevent normal communications operation.

• Baud rate (

bps)

This parameter is for setting the baud rate when communicating with the host device. Set one of "1.2 (1200 bps)", "2.4 (2400 bps)", "4.8 (4800 bps)", "9.6 (9600 bps)", "19.2 (19200 bps)", "38.4 (38400 bps)", or “57.6 (57600 bps)➊”. All units must be set to the same baud rate.

• Communications data length {

len )

This parameter is for setting the communications data length. Set either of "7 bits" or "8 bits". All units must be set to the same communications data length.

• Communications stop bit (

sbit )

This parameter is for setting the communications stop bit. Set either of "1" or "2". All units must be set to the same communications stop bit value.

• Communications parity (

prty)

This parameter is for setting the communications parity. Set one of "none", "even" or "odd". All units must be set to the same communications parity value.

• Send Data Wait Time (

sdwt)

The send data wait time can be set in 1-ms increments between 0 and 99 ms. The default is 20 ms.

Description of operation commands and precautions:

• Communications Writing

Set the Communications Writing parameter to “ON: enabled” or “OFF: disabled” with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. An operation error will occur, however, if enabling or disabling communications writing is set for an event input.

• RUN/STOP

Set control to “run” or “stop” with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. An operation error will occur, however, if RUN/STOP is set for an event input.

•Multi-SP

Set four set points beforehand in the Adjustment group so that you can switch to a desired set point. The setting can be accepted in both setup

Publication 900-UM004D-EN-E - July 2010

Page 38

area 0 and setup area 1. An operation error will occur in the following situations.

– When AT is being executed.

– When the Multi-SP Uses parameter is set to OFF.

– When the Multi-SP Uses parameter is set to ON but multi-SP is set

for an event input (Number of Multi-SP Uses > 0).

• AT Execute/Cancel Set AT (auto-tuning) to “execute” or “cancel” with the related information setting. This command can be accepted in setup area 0 only. An “operation error” will be generated in the following instances:

– When the RUN/STOP parameter is set to “stop”

– When the command is executed in “setup area 1”

– When ON/OFF control is being used

– When 40% AT is specified during 100% AT execution.

– When 100% AT is specified during 40% AT execution.

In addition, a parameter error will occur if 40% AT is specified during heating and cooling control.

Note: If the same type of AT execution is specified during AT execution (e.g., if 100% AT is specified during 100% AT execution), the AT will not be restarted and the operation will end in normal completion with no processing.

•Write Mode Set either the backup mode or RAM write mode with the related information setting. The setting can be accepted in both setup area 0 and setup area 1.

The number of EEPROM (non-volatile memory) write operations is limited. Therefore, use RAM write mode when frequently overwriting data.

Table 2.30

Write Mode Description

The data is written to EEPROM when the parameters in the

Backup mode

RAM write mode

operation/adjustment levels (excluding read-only parameters) are written by communications.

The data is not written to EEPROM when the parameters in the operation/adjustment levels (excluding read-only parameters) are written by communications. Parameters can be changed by operating the keys on the front panel of the controller.

Publication 900-UM004D-EN-E - July 2010

Page 39

Bulletin 900 Communications Procedures 900-TCx (CompoWay/F) 2-23

– When the mode is switched from RAM write mode to backup mode,

the parameters in the Operation/Adjustment groups (excluding read-only parameters) are written to EEPROM.

– The RAM write mode is enabled only when the Communications

Writing parameter is set to “ON” (enabled). Consequently, when the Communications Writing parameter setting is changed to “OFF” (disabled), the parameters in the Operation/Adjustment groups (excluding read-only parameters) are written to EEPROM even if the mode is set to RAM write mode.

•Save RAM Data This command writes the parameters in the Operation/Adjustment groups (excluding read-only parameters) to EEPROM. The setting can be accepted in both setup area 0 and setup area 1.

• Software Reset Restarts processing from the point when power is turned ON. The setting can be accepted in both setup area 0 and setup area 1.

• Move to Setup Area 1 This command moves to “setup area 1” and can be accepted at both setup areas 0 and 1. If the “Initial Setting/Communications Protect” parameter is set to “2,” an “operation error” will be generated, and the move to setup area 1 will be prohibited.

When this move is carried out from setup area 0, the display indicates the Input Type parameter in the “Initial Setting group.” When this operation command is executed in setup area 1, the display will not change.

• Move to Protect Group This command moves to the “Protect group” and can be accepted only in setup area 0.When this command is issued in setup area 1, an “operation error” will be generated, and the move to the protect level will be prohibited.

• Moving to Protect Group in Manual Mode

When this operation command is issued in manual mode, an “operation error” will be generated, and the move to the Protect group will be prohibited.

•Auto/Manual Switch This operation command switches the mode to manual mode or automatic mode, based on the related information setting. This command can be accepted in setup area 0 only. An “operation error” will be generated in the following instances:

– When the command is executed in “setup area 1"

– When auto/manual switching is disabled (not displayed)

When the Controller is switched to manual mode, the “manual manipulated variable” will be displayed. When the Controller is switched from manual mode to automatic mode, the Operation group’s first parameter will be displayed. When the Controller is switched to manual

mode while already in manual mode, the command will be completed normally and the display will not change (the contents will not be refreshed).

• Writing Auto/Manual Status in EEPROM The write mode determines whether the auto/manual status is written to EEPROM.

Table 2.31

Write Mode Description

Backup mode

RAM write mode

Note: When the auto/manual mode is switched with an operation command through communications and the Controller is in RAM write mode, the auto/manual status is not stored in EEPROM. Consequently, if the Controller is restarted by performing a software reset or turning the power OFF and ON again, the auto/manual mode is set to the last saved status.

When the auto/manual mode is switched by communications, the auto/manual status is written to EEPROM.

When the auto/manual mode is switched by communications, the auto/manual status is not written to EEPROM. The status can be written with the Controller key operation.

• Switching to Manual Mode during Auto-tuning If the mode is switched during auto-tuning (AT), the AT will be cancelled and the Controller will be switched to manual mode.

• Parameter Initialization The present settings are returned to the default values and written to EEPROM. This command can be accepted in setup area 1 only. When this command is issued in setup area 0, an “operation error” will be generated.

• Alarm Latch Cancel

1. An operation error will occur if communications writing is disabled or if an EEPROM error occurs.

• Invert Direct/Reverse Operation Inverting or not inverting direct/reverse operation can be selected with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. The related information specifications are written to EEPROM according to the write mode settings. An operation error will occur in the following situations:

– When AT is being executed.

– When inverting direct/reverse operation is set for an event input.

– When executed in manual mode.

•Program Start The simple program function can be reset/started with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. An operation error will be generated if program start has been set in the event input.

•Setting Areas Control operation is executed in setting area 0. In this state, you can perform operations that are permitted only during control or those that cause no problems even if control is in progress. These operations include reading PVs, writing SPs, and change RUN/STOP status. Setting area 0, however, prohibits operations that affect control, including writing data at the initial setting level. (Reading setting data is always allowed.)

In setting area 1, control operation is stopped. In this state, you can perform operations that are not allowed in setting area 0. These operations include writing data at the initial setting level.

At power-ON, the Temperature Controller is set in setting area 0. To move to setting area 1, use the “move-to-setting area 1” command. To return to setting area 0, turn the power OFF and ON again, or use the “software reset” command.

Variable Area (setup range) List

This chapter lists the details of each of the communications data in the Bulletin 900-TCx communications procedures.

For communications using a variable type not enclosed in parentheses in the following table, the set value is double-word data (8 digits). For communications using a variable type enclosed in parentheses, the set value is single-word data (4 digits).

For example, variable type C0 is double-word data (8 digits), and variable type 80 is single-word data (4 digits).

Items expressed in hexadecimal in the “Set (monitor) value” column are the setting range for CompoWay/F (900-TC) communications. The values in parentheses are the actual setting range.

For details of variable areas that are described not in numerical values but by text, refer to the relevant parameter descriptions. For details concerning the operation of these controller parameters, refer to the applicable user manual for the specific controller (See Table 1.3 on page 1-6).

Modbus Communications Procedure

Read this section if you are to communicate using the Modbus format.

Data Format

The data format complies with the Modbus (RTU) communications protocol, so commands from the host computer and responses from the 900-TC8, 900-TC16, or 900-TC32 are contained in data blocks called frames.

The structure of the command and response frames is described below.

In the following explanations, hexadecimal values are expressed by adding the prefix H’ before the number, e.g., H’02. Numbers and alphabetic characters without the H’ prefix are ASCII characters.

Command Frame

When using RTU mode, start with a silent interval of at least 3.5 character times and end with a silent interval of at least 3.5 character times.

4-2 Modbus Communications Procedure

Table 4.1

Silent interval of 3.5 character times min.

Slave address Specify the unit number.

The unit number can be set between H’00 to H’63 hexadecimal (0…99 decimal). Specify H’00 for a broadcast transmission. No responses will be returned for broadcast transmissions.

Function code The function code is a 1-byte hexadecimal code that indicates

the type of command sent from the host device.

Data This is the text data associated with the specified function

code. Specify the required data, such as the variable address or setting data (set in hexadecimal).

CRC-16 Cyclical Redundancy Check

This check code is calculated with the data from the slave address to the end of the data. The check code is 2-byte hexadecimal.

Silent interval of 3.5 character times min.

CRC-16 Calculation Example

Messages are processed one byte at a time in the work memory (a 16-bit register known as the CRC register).

1. The CRC register is initialized to H’FFFF.

2. An XOR operation is performed on the content of the CRC register and

the first byte of the message, and the result is returned to the CRC register.

3. The MSB is packed with zeroes and the CRC register is shifted 1 bit to the right.

4. If the bit shifted from the LSB is 0, step 3 is repeated (next bit-shift processing). If the bit shifted from the LSB is 1, an XOR is performed on the content of the CRC register and A001, and the result is returned to the CRC register.

5. Steps 3 and 4 are repeated until 8 bits are shifted.

6. CRC processing continues to the end of the message, as XOR

operations are performed on the content of the CRC register and the next byte of the message, step 3 is repeated, and the result is returned to the CRC register.

Publication 900-UM004D-EN-E - July 2010

7. The result of the CRC calculation (value in the CRC register) is appended to the last byte of the message.

Modbus Communications Procedure 4-5

No Response

In the following cases, the received command will not be processed and a response will not be returned.

Consequently, a timeout error will occur at the host device.

· The slave address in the received command does not match the communications unit number.

· A parity error, framing error, or overrun error occurred due to a problem such as a transfer error.

· A CRC-16 code error occurred in the received command frame.

· There was a time interval of more than 3.5 character times between data packets that make up the command frame.

Furthermore, the specified function’s processing will be performed but no response will be returned for broadcast functions (slave address = H’00).

Variable Area

The variable area is the region of memory used to exchange data with the 900-TC8, 900-TC16, or 900-TC32 through communications.

Operations such as reading the process value and Reading/Writing parameters are performed on the variable area.

On the other hand, operation commands do not use the variable area.

Figure 4.5

When accessing the variable area, the position of a variable in the variable area is specified with a word identifier, area number, and address in the area.

Addresses

An address is appended to each of the variable types. Express addresses in 2-byte hexadecimal and append them for the specified access size. Each address is composed of a word identifier, area number, and address in the area.

Modbus Communications Procedure 4-7

Modbus Addresses Corresponding to 900-TC (CompoWay/F) Setup Areas 0 and 1

Setup Area 0 and Setup Area 1 do not correspond directly to Modbus addresses, but the following areas have a rough correspondence with one exception.

Table 4.5

Setup Area Modbus Addresses

Area Number Address Range

Setup area 0 00…0B, 20…2B 0000…0BFE, 2000…2B7F Setup area 1 0C…1F, 13…33 0C00…1366, 2C00…3333

Partial Exception to Modbus Address Correspondence

The Hysteresis (Heating), Hysteresis (Cooling), Control Period (Heat), and Control Period (Cool) parameters are assigned to consecutive addresses, but the Control Period parameters are Setup Area 1 parameters. For this reason, an operation error will occur when writing the Control Period (Heating or Cooling) from the Setup Area 0 side, e.g., from the Operation function group.

Number of Elements

The number of elements is expressed in 2-byte hexadecimal. The setting range for the number of elements varies according to the command.

For example, when the number of elements is “0010,” this specifies eight items of data (H’10) from the address.

•Four-byte Mode

One element uses 2 bytes of data, so specify two-element units. Reading and writing in 4-byte units is executed by specifying an even address and specifying the number of elements in multiples of 2.

•Two-byte Mode

One element uses 2 bytes of data, so specify one-element units. Reading and writing in 2-byte data units is executed by specifying 1-element units.

Set Values

The values read from the variable area or written to the variable area are expressed in hexadecimal, ignoring the decimal point position. (Negative values are expressed in 2’s complement format.)

For example, if the 900-TC8 , 900-TC16, or 900-TC32’s process value is read in 4-byte mode when the process value is 105.0, the read value will be H'0000041A (105.0 → 1050 → H'0000041A).

Operation Commands and Precautions

• Communications Writing Set the Communications Writing parameter to “ON” (enabled) or “OFF” (disabled) with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. An operation error will occur, however, if communications writing enable/disable is set for an event input.

• RUN/STOP Set control to “run” or “stop” with the related information setting. The setting can be accepted in both setup area 0 and setup area 1. An operation error will occur, however, if RUN/STOP is set for an event input.

•Multi-SP Set four set points beforehand in the adjustment level so that you can switch to a desired set point. The setting can be accepted in both setup area 0 and setup area 1. An operation error will occur in the following situations.

– When AT is being executed.

– When the Multi-SP Uses parameter is set to OFF.

– When the Multi-SP Uses parameter is set to ON but multi-SP is set

for an event input (Number of Multi-SP Uses > 0).

– When the RUN/STOP parameter is set to “stop”

– When the command is executed in “setup area 1”

– When ON/OFF control is being used

– When 40% AT is specified during 100% AT execution.

– When 100% AT is specified during 40% AT execution.

Publication 900-UM004D-EN-E - July 2010

In addition, a parameter error will occur if 40% AT execution is specified during heating and cooling control.

Note: If the same type of AT execution is specified during AT execution (e.g., if 100% AT execution is specified during 100% AT execution), the AT will not be restarted and the operation will end in normal completion with no processing.

•Write Mode Set either “backup mode” or “RAM write mode” with the related information setting. The setting can be accepted in both setup area 0 and setup area 1.

The number of EEPROM (non-volatile memory) write operations is limited. Therefore, use RAM write mode when frequently overwriting data.

Page 77

Modbus Communications Procedure 4-19

Table 4.15

Write Mode Description

Backup mode The data is written to EEPROM when the parameters in

the Operation/Adjustment function groups (excluding read-only parameters) are written by communications.

RAM write mode The data is not written to EEPROM when the parameters

in the Operation/Adjustment function groups (excluding read-only parameters) are written by communications. Parameters can be changed by operating the keys on the front panel of the controller.

– When the mode is switched from RAM write mode to backup mode,

the parameters in the Operation/Adjustment function groups (excluding read-only parameters) are written to EEPROM.

– The RAM write mode is enabled only when the Communications

Writing parameter is set to ON (enabled). Consequently, when the Communications Writing parameter setting is changed to OFF (disabled), the parameters in the Operation/Adjustment function groups (excluding read-only parameters) are written to EEPROM even if the RAM write mode is set to Disabled.

·RAM Data This command writes the parameters in the Operation/Adjustment function groups (excluding read-only parameters) to EEPROM. The setting can be accepted in both Setup Area 0 and Setup Area 1.

· Software Reset Restarts processing from the point when power is turned ON. The setting can be accepted in both Setup Area 0 and Setup Area 1.

· Move to Setup Area 1 This command moves to Setup Area 1 and can be accepted at both Setup Areas 0 and 1. If the Initial Setup/Communications Protection is set to 2, an Operation Error will be generated, and the move to Setup Area 1 will be prohibited. When this move is carried out from Setup Area 0, the display indicates the Input Type in the Initial Setting function group. When this operation command is executed in Setup Area 1, the display will not change.

· Move Protect function group This command moves to the Protect function group and can be accepted only in Setup Area 0. When this command is issued in Setup Area 1, an Operation Error will be generated, and the move to the Protect function group will be prohibited.

4-20 Modbus Communications Procedure

· Moving the Protect function group in Manual Mode When this operation command is issued in manual mode, an Operation Error will be generated, and the move to the Protect function group will be prohibited.

·Auto/Manual Switch This operation command switches the mode to manual mode or automatic mode, based on the related information setting. This command can be accepted in Setup Area 0 only. An Operation Error will be generated in the following instances:

– When the command is executed in Setup Area 1

– When auto/manual switching is disabled (not displayed)

When the Controller is switched to manual mode, the Manual Manipulated Variable will be displayed. When the Controller is switched from manual mode to automatic mode, the Operation function group’s first parameter will be displayed. When the Controller is switched to manual mode while already in manual mode, the command will be completed normally and the display will not change (the contents will not be refreshed).

· Writing Auto/Manual Status in EEPROM The write mode determines whether the auto/manual status is written to EEPROM.

Table 4.16

Write Mode Description

Backup mode When the auto/manual mode is switched by

communications, the auto/manual status is written to EEPROM. ➊

RAM write mode When the auto/manual mode is switched by

communications, the auto/manual status is not written to EEPROM. The status can be written with the Controller key operations. ➊

➊ When the auto/manual mode is switched with an operation command through communications and the

Controller is in RAM write mode, the auto/manual status is not stored in EEPROM. Consequently, if the Controller is restarted by performing a software reset or turning the power OFF and ON again, the auto/manual mode is set to the last saved status.

Publication 900-UM004D-EN-E - July 2010

Modbus Communications Procedure 4-21

· Switching to Manual Mode during Auto-Tuning If the mode is switched during Auto-Tuning (AT), the AT will be cancelled and the Controller will be switched to manual mode.

· Parameter Initialization The present settings are returned to the default values and written to EEPROM. This command can be accepted in Setup Area 1 only. When this command is issued in Setup Area 0, an Operation Error will be generated. The set values that are set during initialization depend on the command’s related information setting, as shown in Table 4.17.

• Alarm Latch Cancel The applicable alarm latch can be cleared with the related information setting. The setting can be accepted in both setup area 0 and setup area

1. An operation error will occur if communications writing is disabled or if an EEPROM error occurs.

– When AT is being executed.

– When inverting direct/reverse operation is set for an event input.

– When executed in manual mode.

Publication 900-UM004D-EN-E - July 2010

In setting area 1, control operation is stopped. In this state, you can perform operations that are not allowed in setting area 0. These operations include writing data at the initial setting level.

Communications Data for Modbus

This section lists the details of the communications data in the Modbus communications protocol.

Variable Area (Setting Range) List

•Four-byte Mode

One element uses 2 bytes of data (H'0000 to H'FFFF), so specify two element units. Reading and writing in 4-byte units is executed by specifying an even address and specifying the number of elements in multiples of 2.

•Two-byte Mode

One element uses 2 bytes of data (H'0000 to H'FFFF), so specify one element units. Reading and writing in 2-byte data units is executed by specifying 1-element units.

The following table lists the variable area. Items expressed in hexadecimal in the “Setting (monitor) value” column are the setting range in the Modbus specifications. Values in parentheses “()” are the actual setting range.

When there is a section reference for a setting item, refer to that reference for details.
