YOKOGAWA LL1200 Custom Computation Building Tool

■General

The LL1200 Custom Computation Building Tool is a software package that enables you to configure the customized computing functions of a US1000 digital indicating controller on a PC. With the tool, you can configure as many as 65 computation modules, including addition/ subtraction/multiplication, absolute calculation, reciprocal calculation, maximum/minimum/ average calculation, data holding, rate-of-change limitation, limiter operation, integration, timer operation, counter operation, line-segment approximation, inverse line-segment approximation, curved line-segment approximation, ratio calculation, first-order lag calculation, temperature/humidity calculation, temperature correction, pressure correction, output selection, data display, switching, logical AND calculation, logical OR calculation, logical NOT calculation, exclusive OR calculation, comparison, matching, and unmatching. This tool has the same parameter setup functions as the LL1100 parameter setting tool.

■ Custom Computation Building Functions

Custom Computation Function: Develops a custom computation for the US1000 controller by combining computation modules.

• Computation modules

[Arithmetic computations] Addition, subtraction, multiplication, division, absolute value, reciprocal, auto-selector (min./max./average/differ- ence), hold maximum value, hold minimum value, hold, switch, limiter, constant, and multi-selector.

[Logic operations] AND, OR, exclusive OR, NOT, latch, greater, lesser, decremental counter, counter, equal-to, not-equal-to, range, delay, AND (long word), OR (long word), word shift, and edge-triggered counter.

[

Special computations] Sum, timer, rate-of-change limiter, 10-segment linearizer 1 and 2, inverse 10-segment linearizer 1 and 2, curve linearizer 1 and 2, ratio, first-order-lag filter, EU-range conversion, switching between two inputs, temperature and humidity calculation, square-root extraction, detection of change, loop- 1 output selection 1, loop-1 output selection 11, loop-1 output selection 12, loop-1 output  selection 13, loop-2 output selection 2, loop-2 output selection 21, fluid tempera- ture compensation, fluid pressure compensation, 10-segment linearizer 3 and 4, dead time, moving average, edge-triggered timer, Detection of Change at Edge, square-root extraction 2, and flow sum.

[Special functions] Display data unit conversion, parameter setting, data display 1, data display 2, output-1 terminal configuration, and output-2 terminal configuration.

Custom Display Function: The function builds the US1000 controller’s custom displays, according to the user-defined display function created, by configuring display elements and display sequences. Users can select operation displays from the display types provided, and set a display sequence and conditions for them.

Monitor Function: Users can monitor and confirm the behavior of the created custom computation by setting simulated input signals from a personal computer screen.

Communication Function: When the US1000 controller operation is stopped, users can download the created custom computation data to the US1000 and upload custom computation data from the US1000.  It is also possible to compare the custom computa- tion data created using this tool with those in the US1000 controller.

File Management Function: This function allows users to save the custom computation data created with this tool as well as the data uploaded from the US1000 controller onto the hard disk of a personal computer or a floppy disk. It is also possible to compare the custom computation data created with those in the custom computation data files created in the past.

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

■ Parameters Setting Functions

Parameters Setting Function: Sets and changes the control parameters of the US1000 such as the controller mode (US mode), universal input/output selection, setup parameters, and operation parameters.

Tuning Function: This function is used to tune the PID parameters of the US1000 controller. The PID parameters can be tuned and auto-tuning function executed while the PV, SV, and MV trend graphs are being displayed on a personal computer screen.
