[. . . ] R143-E1-01 CX-Process Tool INTRODUCTION GUIDE The CX-Process Tool Operation Manual is included as a PDF file on the CX-One CD-ROM under OMRON/CX-One/CX-Process Tool. Be sure to read the Precautions and other information at the beginning of the manual before using the CX-Process Tool. This CX-Process Tool Introduction Guide describes basic operating procedures for the CX-Process Tool. For application precautions and detailed descriptions, refer to the Help or the PDF Operation Manual. Note: Acrobat Reader 4. 0 or higher is required to display the PDF file. The CX-Process Tool A Loop Controller is a Controller that has the functionality of multiple highperformance Controllers. [. . . ] Next, because a type K thermocouple is being used and the input range is 0. 0 to 500. 0°C, change Data to 1 and click the OK Button. Note: The input type setting (i. e. , parameter) for the CJ1W-PTS51 Isolated-type Thermocouple Input Unit must be set to a type K thermocouple (decimal point) = 0001 hex as given below: DM Area Word Allocated in the CPU Unit D20019 = 0001 hex (When the unit number is 0. ) (It is not necessary to know the address if the setting is made by editing parameters by double-clicking CJ1W-PTS51 in the I/O tables in the CXProgrammer. ) 6-1-4. Set ITEM 010 (Input Range) to 1. 6 Set ITEMs for Function Blocks Click the OK Button. The ITEM Setting Window will close. Click the OK Button. Click the OK Button. The Change PLC Window will open. Click the Settings Button in the Change PLC Window. 1-12 The Network Settings [Toolbus] Window will open. Click the Driver Tab. Set the Port Name to the actual port to be used, and then click the OK Button to close the window. 7 Communications Settings between Computer and PLC 7-2-4. Set the COM port for the computer. Click the OK Button. The communications setting will be completed once the OK Button is clicked once again. Click the OK Button. With the CX-Process Tool, an online connection will be made automatically when online operations, such as downloading, are performed after making the communications settings described above. 1-13 Creating Simple Function Block Data for the Loop Controller 8 Transferring Function Block Data to the Loop Controller Now that communications settings have been completed, transfer the function block data to the Loop Controller. 8 Transferring Function Block Data to the Loop Controller Right-click on the tree in the window at the left and select Transfer to LC from the pop-up menu. Right-click and select Transfer to LC . Click the OK Button. Click the OK Button. Click the OK Button. 1-14 Click the Start Button. The window will automatically close when the download has been completed. Function block data Downloading Loop Controller Click the Start Button. 9 Starting Operation The window to start transferring will be displayed continuing with the transfer operation. Click the OK Button. 8 9 Starting Operation Select Cold Start and click the Execute Button. Select Cold Start for the Run/Stop Command. Click the Execute Button. The operation status display will change to Cold Start when operation has been started. In this example, the operation is started right after downloading, but operation can also be started by using an operation command from the menu, or operation automatically when the power is turned ON (but a hot start will be used by default). Use Hot Start to hold the manipulated variable (MV) and other settings from immediately before a momentary stop. Otherwise, normally use Cold Start. 1-15 Creating Simple Function Block Data for the Loop Controller 10 PID Tuning Tune PID constants for the Basic PID Block. Right-click the Basic PID Block and select Monitor - Tuning Screen from the pop-up menu. Right-click and select Monitor - Tuning Screen. 10 PID Tuning The Tuning Screen Configuration Window will open. At this point, set the tuning screen. For the system configuration specified at the beginning of this guide, the temperature range is to be set to 0. 0 to 500. 0°C. Therefore, input 5000 for the Upper Limit, 1 for the Decimal Point, and deg C for the Unit. Set the temperature range in the Tuning Screen Configuration Window. Click the OK Button. 1-16 The window shown at the right will not be displayed if the PLC is not actually connected. The window, however, is included here as reference. PID tuning Clicking on a setting name will display a dialog box to change the setting. Change the setting with the 10-key pad dialog box (using the mouse) or by using the keyboard. PV SP Operation SP MV The window will be displayed and then trend data will be displayed. PV Upper limit Loop Controller Lower limit 10 PID Tuning 1-17 Creating Simple Function Block Data for the Loop Controller Reference Information G Autotuning (AT) Autotuning is provided as a convenient means for tuning PID control. The following figure shows an example of AT execution and the response of the subsequent temperature control loop. Compared with the response example on the previous page, temperature settings are changed faster. 10 PID Tuning G Fine Tuning (FT) Execute fine tuning (FT) when the control performance produced by autotuning is not acceptable, when autotuning produces instability in the PV, or when interruption of control cannot be allowed. Fine tuning improves control by automatically setting PID constants using three user settings listed below along with fuzzy logic applied to the previous control conditions. · Hunting · Overshooting · Responsiveness Either one or two of the user settings can be set to any of five adjustment levels. For example, to improve control responsiveness and overshooting, the Responsiveness and Hunting parameters can be set to the desired levels. 1-18 11 Uploading and Saving Function Block Data Upload the data from the actual Loop Controller and save the data in a file. Upload the parameters (e. g. , PID constants) tuned in the actual Loop Controller to the computer. [. . . ] Click Function Block reference at the bottom of the menu. The online manual will open and the function block will be explained. This explanation may be useful for reference. To close the window, click the Close Button the window. at the upper right of HMI Function This function automatically assigns function block data (e. g. , PV, SP, and MV) in order of function block address to addresses in the specified bank in the EM Area of the CPU Unit as a constant data conversion area. The blocks that are allocated are determined according to the block addresses given to the registered function blocks. For example, the block address will be 001 if the Basic PID Block is pasted first. [. . . ]
