YOKOGAWA LL100 Parameter Setting Tool

■General

The LL100 Parameter Setting Tool is a software package that enables you to set the functional configuration parameters (setup parameters) and operation parameters of a digital indicating controller and a program controller, as well as the program patterns of a program controller, on a PC. The tool lets you the followings:

• Setting parameters
• Uploading, downloading and comparing the parameters in the controllers
• Saving and reading the parameters stored on the storage media
• Printing out parameters
• Multi-monitoring

■Parameters (Program) Setting Functions

Sets and changes the controller’s parameters such as the controller mode (UT/UP mode), universal input/output selection, setup parameters, operating parameters, and program pattern parameters* (program/start conditions and patterns). Note: Uploading/downloading/comparing parameters via Ethernet is impossible for the controller operated by custom computation function (UT mode 21 or UP mode 21).  Use front communication or serial terminal communication. *: For program controllers only.

Tuning Function: This function is used to tune the PID parameters of the controllers. The PID parameters can be tuned and the auto- tuning function can be executed while the trend graphs of PV, SP, and control output are being displayed on a personal computer screen.

Downloading, Uploading, and Comparing Parameters: When the controller operation is stopped, users can down- load the created parameter data to the controller and upload the parameter data from the controller. It is also possible to compare the parameter data created using this tool with the data in the controller.

File Management Function: This function allows users to save the parameter data created using this tool and those uploaded from the controller to the hard disk of a personal computer or a floppy disk. It is also possible to compare the parameter data created using this tool with those in the parameter files created in the past.

Printout Function: Parameter data can be printed out from a printer connected to a personal computer.

■Multi-monitoring Function

This function allows users to display and collect PV, SP, control output and alarm generating state as trend data. It is possible to detect two or more controllers (a maximum of 16 loops) connected to the personal computer automatically, and to display trend graphs on a personal computer screen.

Tuning Function: This function is used to tune the PID parameters of the controller. The PID parameters can be tuned, the auto-tuning function can be excuted for every connection loop and an operating mode can be changed while the trend graphs of PV, SP and control output are being displayed on a personal computer screen.

File Management Function: The trend data collected by the monitoring function can be saved as a CSV format so that commercial spreadsheet software like Microsoft Excel can treat data. The saved trend data can be read and displayed as trend graph.
