1. Overview

● The Multi-monitoring function allows users to display and collect “measured input value”, “current setpoint”, “control output” and “alarm generating state” of GREEN Series controller as trend data. The GREEN Series controllers connected to the personal computer can be detected automatically by Automatic scan, and the trend data is displayed on a personal computer screen. The data of a maximum of 16 loops (*1) can be collected at the same time. A maximum of 16 trend data can be displayed on a chart screen. Trend display cycle: 1 to 3600 sec (variable) Trend display times: 65000 times (fixed regardless of a trend display cycle)

● The Panel view shows measured input value, current setpoint, control output and alarm generating state of the connected loop.

● The collected trend data can be outputted as a CSV format so that commercial spreadsheet software like Microsoft Excel can treat.

● The saved trend data can be read out and displayed as trend graph.

● T uning can be carried out for every connected loop. Auto-tuning, change of PID param-

eters, change of operation mode and the like can be carried out.

*1: One unit of the following controllers uses two loops: UT750/UP750 cascade control, dual-loop control, temperature and

humidity control and cascade control with two universal inputs, UT550/UT551/UT520/UP550 cascade control.

4. Setting the Multi-monitoring Function

This chapter describes how to set the Multi-monitoring function.

4.1 Automatic Scan

This function allows to detect the GREEN Series controllers connected to the personal computer automatically .

After you choose Start Monitor in the Multi-monitor Starting dialog box (Figure 2.1.2), the Automatic Scan dialog box (Figure 4.1.1) appears. The following three ways can be used for communication.

• Front communication (Optical communication adapter)

• Terminal communication (Serial communication)

• Terminal communication (Ethernet communication)

4-1

Figure 4.1.1 Automatic Scan Dialog Box

NOTE

Front communication (Optical communication adapter), Terminal communication (Serial communication) and Terminal communication (Ethernet communication) cannot be used for communication (monitoring) at the same time.

● Operation Procedure

(1) Click Front communication. (2) From the Serial port list, select the communication port of the personal computer from

COM1 to COM16.

(3) Connect the controller to the personal computer, and then click Execute. (4) The T rend Setup dialog box (Figure 4.2.1) appears after Automatic scan is completed.

■ T o Monitor via Serial Communication Terminals

● Operation Procedure

(1) Click T erminal communication (Serial). (2) From the Serial port list, select the communication port of the personal computer from

COM1 to COM16.

(3) Set the RS485 communication parameters.

Select communication speed, parity , data length and stop bit from the drop-down lists. Make the same RS485 communication settings in the target controller.

(4) Set the Scanning start address and Scanning end address (5) Connect the controller to the personal computer, and then click Execute. (6) The Scanning address and the Number of detected loops are displayed during Auto-

matic scan.

(7) When the 16 loops are detected after starting scanning, the scanning to the Scanning

end serial address is completed or Cancel is clicked, Automatic scan stops and the Trend Setup dialog box (Figure 4.2.1) appears. When interrupted on the way, the loops already detected by that time can be monitored.

NOTE

Discontinuous values like 1, 3, and 5 can be set for each controller as serial address. However, continuous values can shorten time required for Automatic scan.

NOTE

One unit of the following controllers uses two loops: UT750/UP750 cascade control, dual-loop control, temperature and humidity control and

cascade control with two universal inputs UT550/UT551/UT520/UP550 cascade control. If the controller above is connected to the 16th loop for Automatic scan, the 16th loop is

judged that it does not exist, and Automatic scan stops. The detected 15 loops can be monitored.

IM 05G01B12-02E

1st Edition : 2004.11.05-00

NOTE

Communication via serial terminal communication is possible only for GREEN Series controllers with RS485 communication (optional function). For controllers without RS485 communication, always select Front communication.

To communicate via serial terminal communication, set the target controller’s RS485 communication protocol to PC-link communication. With other protocol, the serial terminal communication is unavailable. In addition, the RS485 communication parameters (communication speed, parity , stop bit and data length) of both the target controller and the personal computer must be the same.

For the 300 series of old GREEN Series, communication via serial terminal communication is possible only for the controllers with the communication function.

For the 300 series of GREEN Series, select Front communication or Serial terminal communication using the LL operating parameter . To select Serial terminal communication, set the LL parameter to OFF.

● Operation Procedure

(1) Click T erminal communication (Ethernet). (2) Set the target controller’s IP address (Scanning start IP address and Scanning end IP

address), and RS485 communication address (Scanning start serial address and Scanning end serial address) in the text box.

(3) Connect the controller to the personal computer, and then click Execute. (4) The Scanning address and the Number of detected loops are displayed during Auto-

matic scan.

(5) Automatic scan starts at the Scanning start serial address of the Scanning start IP

address. After scanning the Scanning end serial address, the scanning of the next IP address is started. Clicking Skips to the following IP address during scanning transfers to the next IP address regardless of the serial address at that time.

NOTE

By stopping the trend display , it will be in a trend display stop state. In this manual, the state where the trend display is not performed and the trend data file is opened is named generically “The trend display is stopped.”

NOTE

If opening a saved trend data file while the trend display is stopped, and then starting the trend display again, the Automatic Scan dialog box appears. T rend display can be started after Automatic scan and the setup for trend display are completed.

NOTE

The Multi-monitor tool can hold a maximum of 65000 times of trend data regardless of a trend cycle. When exceeds 65000 times, trend data is discarded from old data. Periodical saving of monitored data as a file is recommended. The saved data is the trend data of the time of data saving. If the trend cycle is 5 seconds (data acquisition per 5 seconds), data saving of about 90 hours is continuously possible.

5.3 Saving T rend Data

Trend data can be saved while trend display is working or stopped. Measured input value (PV), current setpoint (CSP), (heating-side) control output (OUT),

cooling-side control output (OUTc), alarm generating state and tuning data (if recorded in the Tuning display) of all the loops detected automatically can be saved as a CSV file.

● Operation Procedure

(1) From the toolbar, click the [ ] shortcut, or from the menu bar, choose File, and then

Save trend data.

(2) The Save T rend Data dialog box (Figure 5.3.1 or Figure 5.3.2) appears. In the File

name text box, enter a file name then click Save.

Trend display cycle can be changed while trend display is working or stopped.

● Operation Procedure

(1) From the status display bar, double-click T rend cycle, or from the menu bar , choose

Multi-monitor, then Change trend cycle while trend display is working or stopped.

(2) The T rend Cycle dialog box (Figure 5.4.1) appears. The setting range is 1 to 3600 sec.
