[. . . ] 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. [. . . ] Ao 4-point (DA041) in the tree in the window on the left. Setting Communications Conditions 7-2-1. Right-click and select Change PLC. A dialog box will open. 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. When finished, click the OK Button. 10-2. 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. To perform autotuning, click the AT Button. The PID constants will be tuned when autotuning is started. The following figure shows an example of AT execution and the response of the subsequent temperature control loop. [. . . ] For example, the block address will be 001 if the Basic PID Block is pasted first. A total of 40 words (fixed) are allocated for each block address: 20 words for send data from the Loop Controller to the CPU Unit memory (E00000 + block address x 20, i. e. , E00020 to E00039 if the block number is 001) and 20 words for receive data from the CPU Unit memory to the Loop Controller (E15000 + block address x 20, i. e. , E15020 to E15039 if the block number is 001). Block address The ITEMs for which memory is allocated depends on the function block, but with the Basic PID Block, for example, ITEMs will be transferred as shown in the following figure. Example: Basic PID (Block Model 011) (Offset from Beginning Word) Word Analog data +18 Bit Bit data +19 Allocated addresses can be output as a list in a CSV file by selecting Execute - Create Tag File - Create HMI I/F Memory Map. Useful Functions User Link Tables User link tables are used to exchange data between user-set I/O memory in the CPU Unit and function blocks in the Loop Controller. Normally, Field Terminals are used for data exchange with I/O Units and the HMI function is used for data exchange with I/O memory for CPU Units. With these functions, however, the I/O memory addresses for the CPU Unit are automatically allocated. [. . . ]
