How can I transmit custom computation data?

(ns-faq-green-9064-spec)

Transmit them in the order: Custom computation data → parameter settings.

When I set the user parameter unit to EU or EUS on the custom computation building tool, I can't input a value in the initial value cell.

(ns-faq-green-9115-soft)

Since the custom computation building tool cannot hold AINn and PVn scale data, the limit check cannot be performed on the input value when you select EU or EUS for the unit. Therefore, it prevents you from entering a value. If the unit is set to EU ...

What is the purpose of the LL password for the custom computation creation tool?

(ns-faq-green-9114-soft)

This is for securing readout of custom computation information. If you set an LL password when downloading, it will be required for uploading, computation monitoring, and executing comparisons with the controller. Even if a password is set, it is not...

Can I extend the LL100/LL200 cable?

(ns-faq-green-9093-soft)

Yes. Use a standard USB extension cable. Note that per the USB standard you should not use an extension cable longer than 4 meters.

How long is the included cable of LL100/LL200?

(ns-faq-green-9092-soft)

2.7 meters.

Can I purchase an adapter or cable for LL100/ L200 separately?

(ns-faq-green-9094-soft)

No. LL100/LL200 has been discontinued.

Can I purchase separate cables for LL100/LL200?

(ns-faq-green-9091-soft)

No. LL100/LL200 has been discontinued.

A timeout error occurs during communication with the LL.

(ns-faq-green-9079-spec)

The adapter might not be attached properly, or the adapter batteries (2 x AA) may be spent. If using the UT320/321/350/351, check whether the LL parameter on the main unit is ON.

When U*M=21, the DO command button in the setup menu screen is unavailable so I can't enter settings.

(ns-faq-green-9105-soft)

The DO settings are made unavailable to protect the DO connection set in the custom computation tool (in the same manner, the controller main unit also skips the display) If you want to change the U*M=21 DO, use the custom computation creation tool. ...

When U*M=21, I can only set the message text in the DI setting screen of the setup menu screen.

(ns-faq-green-9106-soft)

The DI settings are made unavailable to protect the DI connection set in the custom computation tool. (in the same manner, the controller main unit also skips the display) If you want to change the U*M=21 DO, use the custom computation creation tool....

When I write U*M=21 to the controller I get the message, "Could not write U1 user parameter due to U1 unit mismatch," and I can't set the user parameter setting value on the controller.

(ns-faq-green-9104-soft)

This is because the unit of the controller's user parameter differs from the unit specified in the parameter setting tool. You will have to either use the unit from the controller on the parameter setting tool, or use the custom computation build...

Is there any sample custom computation data?

(ns-faq-green-9065-program)

Sample data is available for each control mode. We recommend that you modify these samples to create your own.

What accessories are required for custom computation of UT750/UP750/US1000?

(ns-faq-green-9061-select)

The software program LL200 (sold separately) is required for the UT750/UP750, and LL1200 (sold separately) is required for the US1000.

I can't set R485 parameters for the UT320, UT321, UT350 and UT351 using the parameter setting tool.

(ns-faq-green-9103-soft)

We apologize for this. These parameters cannot be set using the tool (both terminal and front panel communications) due to the specifications of the controller main unit.

A response time out occurs during communication on the UT320, UT321, UT350, or UT351.

(ns-faq-green-9101-soft)

Check whether the LL parameter on the controller is ON. If using RS-485 communication, turn it OFF. If it is already OFF, check the following. If front panel communication, ON If rear panel communication, OFF If it is already OFF, check the following...
