What Are the Benefits of the LL50A Parameters Setting Software?

 

Parameter Setting Function

Parameter Setting Display

Parameters that determine controller functions can easily be set:

controller model type, controller mode (single-loop control, cascade control, loop control with PV switching, etc.), universal input/output functions, setup parameters and others.

 

Tuning Function

Tuning Display

Used to tune a controller's PID parameters. Displays measured input value, target setpoint, and control output value as a trend graph on a personal computer screen, allowing PID parameter modification, AUTO/MAN switching, control output modification in manual operation, etc.

 

Ladder Program Building Function

Ladder Program Building Display

Ladder sequence programs can be created and ladder programs can be monitored.

 

Network Profile Creation Function

Can be used to create an electronic device data sheet for PROFIBUS-DP communication.

(ns-faq-ut-2151-setting)
MODE (operation mode) related parameters do not appear.
Can I purchase an English version of the LL50A setting tool?
(ns-faq-ut-2161-select)
The LL50A supports Japanese and English. The installer detects the language of the OS automatically.
There are no operation keys on the /MDL DIN rail attachment model. How can I perform autotuning?

Autotuning can be executed from the LL50A tuning monitor.
I installed the LL50A. I want to write the UT settings to a PC, but I get the following error message. "Failed to upload instrument information. Check the communication connection and conditions."
(ns-faq-ut-2190-setting)
When you install the LL50A, two icons are create on the desktop. To write settings, launch the Setting Tool by clicking its icon.
Can I switch the language of LL50A from Japanese to English?
(ns-faq-ut-2199-setting)
Yes, in version R6.02.01 and later.Use File>Settings>Language. If parameters are not displayed, install the latest version of LL50A.
Communication on the LL50 setting tool isn't working.
(ns-faq-ut-2211-setting)
Check the following. Whether the dedicated cable is securely inserted into the adapter. The position of attachment to the front of the controller. In Device Manager, under Ports (COM and LPT), confirm that "Yokogawa USB Serial Port" ap...
I want to apply protection to a ladder program created on LL50A.
(ns-faq-ut-2212-setting)
You can protect it with a unique user password.
Can I use a commercially available USB cable for LL50A?
(ns-faq-ut-2242-connect)
No, please use the included cable when you purchase LL50A.
What’s the password I need to enter in LL50A to restore factory defaults on the controller?
(ns-faq-ut-2244-setting)
The password is UTAdvanced_INIT.
What’s the password I need to enter in LL50A to restore user defaults on the controller?
(ns-faq-ut-2245-setting)
The password is UTAdvanced_INIT_SET.
When reading UT data on LL50A, the DCU version of the system data is R0.00.00. Is that normal?
(ns-faq-ut-2250-spec)
Yes. For LL50A communication that uses the maintenance port, the DCU version is R0.00.00.
I'm editing a CC-Link communication profile on the LL50A. I want to add the UT32A-D type to the RS485 communication line, but the PV2 register symbol doesn't appear.
(ns-faq-ut-2168-setting)
Select Modbus slave device UT32D.
I purchased a DIN rail mount UTAdvanced series, but how should I configure it?
(ns-faq-ut-2165-spec)
Use the LL50A Parameter Setting Software, sold separately.
I want to perform cascade control of 2 temperature inputs on a single unit. Is there a model that can do that?
(ns-faq-ut-2193-select)
Yes, the UT75A + LL50A setting software (sold separately) can handle that.
When using the LL50A to create ladder programs, which ladder program edit mode should I use: "input ladder calculation," "output ladder calculation," or "user ladder"?
(ns-faq-ut-2030-program)
Generally you should create programs in "user ladder" mode. If needed, you can rewrite the input ladder and output ladder portions.
I'm creating ladder programs on the LL50A. I want to set input computed results to R.SP, but I see lots of digits are displayed after the decimal point of the data on the ladder monitor. Can I reduce the number of digits displayed after the decimal point?
(ns-faq-ut-2031-program)
The DATA register uses a 4-byte floating point number, therefore it displays a lot of digits. Try using the K or P registers, since they handle 2-byte integer data.
Can I disable ladder programs that I used?
(ns-faq-ut-2034-setting)
On the LL50A, change the system data's ladder sequence function from USE to DON'T USE. If not using the LL50A, initialize the main unit.

Can I change the temperature controller profile information for CC-Link communication?
(ns-faq-ut-2068-spec)
You can change it if it is in a user profile (profile no. 0).To create a user profile, use the LL50A network profile tool.
With the LL50A and UTAdvanced, can I perform RS-485 communications without a dedicated cable?
(ns-faq-ut-2051-connect)
Yes, if using a UTAdvanced series instrument with the RS-485 communication option. Set the RS-485 protocol on the main unit to 8 (MBRTU: Modbus RTU). The initial value is 8. Select RS-485 in the LL50A communication execution screen, and make the comm...
How can I display parameters that aren't displayed in the LL50A parameter setting software?
(ns-faq-ut-2052-soft)
If the LL50A's display setting is not PRO, some parameters won't display. Change the LL50A's display parameter as follows: Display > Parameter > Display level > Professional. The LL50A's display level must be set separately f...
After changing the UT's SP values from the MELSEC via CC-Link, when I change the SP value on the UT main unit, I can't change to the same value as before from the MELSEC.
(ns-faq-ut-2026-connect)
As for individually writing parameters via CC-Link, changing OUT area values constitutes a write request. In your case, since the OUT area value hasn't changed from the previous value, the SP value is notoverwritten. As a fix, periodically copy t...
Can I convert GREEN series (UT300/UT400/UT500/UP500) parameters for use with the UTAdvanced series?
