1. Overview
First read the LL200 PC-based Custom Computation Building T ool user’s manual to
familiarize yourself with the basic operation of the LL200 and examples of custom
computations. Then, read this manual when you actually configure your own custom computations and display functions.
This manual explains the computation modules you will use when customizing the
built-in computations with the LL200 PC-based Custom Computation Building T ool.
It also discusses the operating display functions you will use when configuring
customized display functions. See the following summary for information on what
each chapter discusses and for what purpose it is written.
■ Information and Purpose Covered by Each Chapter
● Chapter 2 Computation Block Diagrams for Individual UT Modes
Shows the diagrams of the UT750’s standard computation blocks that can be customized
(i.e. the input block and output block). See this chapter when you configure custom computations by modifying the standard computation blocks supplied as the LL200’s sample files.
A single look at these diagrams allows you to easily understand the computation blocks for
controller modes (UT modes) 1 to 15.
1-1
● Chapter 3 T ypes and Ranges of Computation Data
Lists the types and ranges of signals coming in and going out of input and output blocks.
See this chapter when configuring custom computations because you must verify the types
and ranges of signals that apply to the blocks.
● Chapter 4 List of Computation Modules and Their Functions
Explains the functions of the computation modules in detail, along with the number of
inputs and the data types used in each computation module. See this chapter when you
want to know the functions of modules you will use when creating custom computations.
● Chapter 5 UT750 Data Storage Areas (D Registers and I Relays)
Explains the data items stored in the UT750 controller.
These data items can be linked to the input and output terminals of the computation mod-
ules. They also include process data, parameter data and flag data. See this chapter when
creating custom computations.
● Chapter 6 Operating Display Functions
Lists operating display patterns, along with their display contents. See this chapter when
you configure operating display functions.

2. Computation Block Diagrams for Individual UT Modes
This chapter describes the UT750’s customizable computation blocks (more specifically , the input/output blocks shown in Figure 2.3) for the standard controller modes
(UT modes).
Since this chapter lists the input/output blocks for all the standard controller modes
(UT modes 1 to 15), you can refer to this chapter when configuring custom computations using the LL200’s sample files.
Figure 2.3 shows the whole view of the UT750’s functional structure, focusing on the
input/output blocks and signals that go in and out of the input/output blocks. This
figure thus clarifies where the input and output blocks are positioned within the
functionality of the UT750.
Figures 2.4 and after are diagrams of the input and output blocks for each controller
mode (UT mode).
