1. OUTLINE

This manual describes Modbus/TCP protocol communication when the temperature control module for Ethernet V-TIO-P or V-TIO-Q (hereafter called the V-TIO-P/V-TIO-Q module) for the module type controller SRV is used.

• The V-TIO-P/V-TIO-Q module has one modular connector (RJ-45) for connection to Ethernet.

• Up to 30 temperature control modules (V-TIO-A, B, C or D) can be connected to one

V-TIO-P/V-TIO-Q module.

Modbus/TCP is an open field network provided with the Modbus protocol on the TCP/IP protocol of Ethernet.

The data request side is called “client” (such as computer) and the data response (supply) side is called “server” (SRV).

Basically, one client corresponds to one server (SRV) (i.e. one to one). However, one client can communicate with two or more servers depending on the program on the client side, but two or more clients cannot communicate with one server.

For specification, parts description and wiring of the V-TIO-P/V-TIO-Q module, see

Temperature Control Module for Ethernet V-TIO-P/V-TIO-Q Instruction Manual (IMS01P08-E).

6. IP ADDRESS SETTING

Set an IP address of a V-TIO-P/V-TIO-Q module. Three types of IP address setting are available: “setting by Telnet,” “setting by Web browser” and “setting by DIP switch.”

Confirm the IP address number to the network administrator of the network (LAN) to

which the V-TIO-P/V-TIO-Q module is connected.

6.1 Setting by Telnet

Set the IP address by the software “Telnet” attached to Windows.

 Preparations before setting

When setting the IP address by Telnet, it is necessary to coincide the 1st to 3rd bytes and masking range of the IP address of the client (computer) which starts Telnet with those of the IP address of the V-TIO-P/V-TIO-Q module.

1. Connect the V-TIO-P/V-TIO-Q module and client, and then turn on the power.

For wiring procedure, see 5. WIRING (P. 12).

2. The IP address of the V-TIO-P/V-TIO-Q module is set to a factory set value of “192.168.1.1.” As it is necessary to coincide the 1st to 3rd byte values of this IP address with those of the IP address of the client, change the IP address of the client to “192.168.1.” (: Any value in the range of 0 to 255, but other than 1).

3. As the subnet mask of the V-TIO-P/V-TIO-Q module is “255.255.255.0,” also change the subnet mask of the client to “255.255.255.0.”

After the IP address of the server is set, return the present IP address of the client to the original address or change to the address meeting the network to be connected.

It is possible to set the IP address of the V-TIO-P/V-TIO-Q module using the client already connected to the network. However, as the IP address of the client is changed, that client is disconnected from the network so far connected. In addition, when setting the IP address by this method, confirm to the network administrator whether or not no problem arises.

16 IMS01P09-E4

6. IP ADDRESS SETTING

 Setting example

An example of setting the IP address to “192.168.1.3” is shown in the following.

1. Display the MS-DOS prompt (command prompt); enter the following command and then press the Enter key.

C:¥>telnet 192.168.1.1 9999

2. Device information on the module (V-TIO-P/V-TIO-Q module) whose IP address is “192.168.1.1” is displayed. Finally, as the message “Press Enter to go into Setup Mode” is displayed, press the Enter key to go into Setup Mode.

MAC address 00204A8064BD Software version 01.3 (030612) XPTE

Press Enter to go into Setup Mode

If the timing of pressing the Enter key is late, the message “Connection with Host was cut off” is displayed and thus the client is disconnected from the V-TIO-P/V-TIO-Q module. Therefore if the message “Press Enter to go into Setup Mode” is displayed, immediately press the Enter key. If disconnected, try again from “1.”

3. If entered into Setup Mode, the present Ethernet information is displayed. Finally, eight choices are displayed as “Change Setup:.” Therefore enter “0” after “Your choice ?” and then press the Enter key.

6. IP ADDRESS SETTING

6.2 Setting by the Web Browser

It is possible to set the IP address by using the Web browser (such as Internet Explorer).

 Preparations before setting

When setting the IP address by Web browser, it is necessary to coincide the 1st to 3rd bytes and masking range of the IP address of the client (computer) which starts Web browser with those of the IP address of the V-TIO-P/V-TIO-Q module.

1. Connect the V-TIO-P/V-TIO-Q module and client, and then turn on the power.

For wiring procedure, see 5. WIRING (P. 12).

2. The IP address of the V-TIO-P/V-TIO-Q module is set to a factory set value of “192.168.1.1.” As it is necessary to coincide the 1st to 3rd byte values of this IP address with those of the IP address of the client, change the IP address of the client to “192.168.1. ” (: Any value in the range of 0 to 255, but other than 1).

3. As the subnet mask of the V-TIO-P/V-TIO-Q module is “255.255.255.0,” also change the subnet mask of the client to “255.255.255.0.”

After the IP address of the server is set, return the present IP address of the client to the original address or change to the address meeting the network to be connected.

It is possible to set the IP address of the V-TIO-P/V-TIO-Q module using the client already connected to the network. However, as the IP address of the client is changed, that client is disconnected from the network so far connected. In addition, when setting the IP address by this method, confirm to the network administrator whether or not no problem arises.

7.5.2 Data processing precautions

 With this protocol, the maximum number of channels is 62.

 If data range or address error occurs during data writing, the data written before error is in effect.

 Some communication data may become invalid depending on the module selection or the

configuration of the server (SRV). Under conditions listed below, no error response message will occur.

− When ON/OFF control, proportional band, integral time and derivative time are invalid.

− When current/voltage output, proportioning cycle time are invalid.

− When only the heater break alarm function is provided, current transformer input measured value,

heater break alarm status, heater break alarm set value and number of heater break alarm delay times are valid.

− When only the control loop break alarm (LBA) function is provided, control loop break alarm (LBA) status, use selection, time and deadband are valid.

Do not write data to any address which is not described in a list of data maps.

7.6.2 Initial setting data items

The Initial setting data should be set according to the application before setting any parameter related to operation. Once the Initial setting data is set correctly, those data is not necessary to be changed for the same application under normal conditions. If they are changed unnecessarily, it may result in malfunction or failure of the instrument. RKC will not bear any responsibility for malfunction or failure as a result of improper changes in the Initial setting.

 Transfer to initial setting mode.

Transfer to initial setting mode sets in “1” with register address 7D20H (normally setting mode).

The instrument cannot be changed to the initial setting mode state at control start

(during control). If it needs to be changed to the above state, first stop the control by “Control RUN/STOP transfer.”

No control can be started during initial setting mode. If the control needs to be

re-started, first change the instrument the normal setting mode state (set register

address 7D20H by 0).

When the setting change rate limiter is used, the SV will also ramp up or ramp down by the function at power-on and operation mode change from STOP to RUN.

If the autotuning (AT) function is activated while the SV is ramping up or ramping down by the setting change rate limiter, AT will starts after the SV finishes ramp-up or ramp-down by the limiter, and the controller is in PID control mode until AT starts.

If the rate of setting change limiter is set to any value other than “0.0: OFF (Unused),” the event re-hold action to be taken by a set value (SV) change becomes invalid.

Use to transfers PID control and autotuning (AT).

Attribute: R/W (Read and Write) Number of data: 62 (Data of each channel) Data range: 0: PID control operation

1: AT (Autotuning) operation

Related parameters: AT differential gap time (P. 75), AT bias (P. 76) Factory set value: 0: PID control operation Function: Autotuning (AT) function automatically measures, calculates and sets the

optimum PID constants. The followings are the conditions necessary to carry out autotuning and the conditions which will cause the autotuning to stop.

Requirements for AT start Start the autotuning when all following conditions are satisfied:

• Operation mode conditions are as follows:

− Auto/Manual transfer → Auto mode

− PID/AT transfer → PID control mode

− Control RUN/STOP transfer → Control RUN mode

• The measured value (PV) is without input error range [Input error determination point

(high) > Measured value (PV) > Input error determination point (low)].

• The output limiter high limit is 0.1 % higher and the output limiter low limit is 99.9 % or less.

• When operation mode is set to “Control.”

When the autotuning is finished, the controller will automatically returns to “0: PID control operation.”

AT cancellation The autotuning is canceled if any of the following conditions exist:

• When the temperature set value (SV) is changed.

• When the PV bias value is changed.

• When the AT bias value is changed.

• When the Auto/Manual mode is changed to the Manual mode.

• When the measured value (PV) goes to input error range [Measured value (PV) ≥ Input error determination point (high) or Input error determination point (low) ≥ Measured value (PV)].

• When the power is turned off.

• When the module is in the FAIL state.

• When the PID/AT transfer is changed to the PID control.

• When operation mode is set to “Unused,” “Monitor 1” or “Monitor 2.”

• When the Control RUN/STOP function is changed to the “Control STOP.”

If the AT is canceled, the controller immediately changes to PID control. The PID values will be the same as before AT was activated.

Caution for using the Autotuning (AT) When a temperature change (UP and/or Down) is 1 °C (1 °F) or less per minute during Autotuning, Autotuning may be cancelled before calculating PID values. In that case, adjust the PID values manually. It is possible to happen when the set value is around the ambient temperature or is close to the maximum temperature achieved by the load.

When control loop break alarm (LBA) is used, control loop break alarm (LBA) time is automatically calculated by AT. However, the calculated data becomes valid by changing to the initial setting mode once after AT is executed.

The Initial setting data should be set according to the application before setting any parameter related to operation. Once the Initial setting data is set correctly, those data is not necessary to be changed for the same application under normal conditions. If they are changed unnecessarily, it may result in malfunction or failure of the instrument. RKC will not bear any responsibility for malfunction or failure as a result of improper changes in the Initial setting.

 Setting procedure of initial setting data items

WARNING

When AT function is activated or the controller is in STOP mode, the LBA function is not activated.

If the LBA setting time match the controlled object requirements, the LBA setting time should be adjusted. If setting time is not correct, the LBA will malfunction by turning on or off at inappropriate time or not turning on at all.

While the LBA is ON (under alarm status), the following conditions cancel the alarm status and LBA will be OFF.

• The measured value (PV) rises beyond (or falls below) the LBA determination range within the LBA time.
