■General
The LL100 PC-based Parameters Setting Tool is a software
package used to set the setup parameters, operating
parameters, and program patterns* of the GREEN Series
controllers from a personal computer. This tool allows
users to download, upload, print out parameters, and
display PV trend data during PID tuning, etc.
The multi-monitoring function can detect two or more
controllers automatically, and can display or save trend
data like PV, etc.
*: For program controllers only .
■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 autotuning 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 download 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.
(with Multi-monitoring Function)
■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.
■Parameter Setting Function for
Ethernet Converter
Sets the parameters related to the Ethernet communication
function of the Ethernet/RS485 converter, VJET.

■Connection between the Controller and a Per-
sonal Computer
[Via Dedicated Adapter]
By attaching a dedicated adapter to the controller’s front
panel, users can upload and download parameter data to and
from a personal computer.
To communicate via the dedicated adapter:
Dedicated adapter
(optical/electrical signal converter)
Controller
Dedicated cable
Personal
computer
USB terminals
[Via RS-485 Communication Terminals]
Users can also upload and download parameter data to and
from a personal computer via the rear communication
terminals of the controller. This connection requires an RS232C/RS-485 converter (ML2).
To communicate via the communication terminals:
[Via Ethernet Communication Terminal]
The UT351-xA/UT551-xA to xD controllers can communicate with a personal computer via the Ethernet communication terminal. Connect a personal computer and a communicable network using a cable that meets the 10BASE-T/
100BASE-TX standards. Also, the UT351-xA/UT551-xA to
xD controllers and VJET converter can use the Ethernetserial gateway function to communicate with the GREEN
Series controllers equipped with the communication
functions via network. In this case, cross-connect the rear
communication terminals of the UT351-xA/UT551-xA to
xD/VJET and of the GREEN Series controllers.
