UTAdvanced^® Digital Indicating Controllers

This is an introduction to ladder programs using the ladder sequence function that comes standard with the UTAdvanced series of Digital Indicating Controllers.

With UTAdvanced, various parameters are displayed on the front panel, and can be set using keys. Timer commands and other lines in ladder programs require time settings, and it is common to set a previously determined value. However, there are often situations where you wish to change time settings based on the overall system's operating conditions and other factors.

With a UTAdvanced ladder program, a parameter (P parameter) is available for setting and changing time settings with key operations.

The following shows the use of the P parameter to change time settings.

Description of Action

• TIM (timer) command starts when DI1 (contact input) is turned ON.
• The TIM command performs subtraction at the time set for P01 (P parameter) at CLK1 (operates at a 1-second period).
• When time is up, the TIM relay (timer 1 relay) turns ON.

Regarding the P Parameter

Up to ten P parameters (P01–P10) can be registered for use. In the case of the P01 parameter above, the unit of time is seconds because the TIM command’s unit of time is defined as seconds. For other uses, you can define decimal places to customize the units as needed (note that decimal place settings can only be modified using the LL50A Parameter Setting software).

The Map parameter is attached below.
