1.Overview

Chapter 1 Overview

This chapter first explains what custom computation is and then introduces the tool used to configure these computations and the model and suffix codes of the US1000 controller models to which the tool applies.

This chapter also discusses the system requirements that must be met to be able to use the LL1200 tool and shows external views of the dedicated adapter and cable.

1.1Function Overview of the LL1200 Tool

The LL1200 tool is designed to run on a personal computer connected to the US1000 controller. You can set a variety of functions for the US1000 controller from the personal computer. Inversely, you can read the settings from the US1000 controller.

In addition to these operations, you can set the various parameters of the US1000. This particular function is the same as the one offered by Model LL1100 PC-based Parameters Setting Tool, another tool used with the US1000 controller. This manual does not therefore discuss this function in particular. When you use this function in your practical applications, refer to the Model LL1100 PC-based Parameters Setting Tool instruction manual (supplied together with this manual).

1-1

The US1000 controller comes with built-in control functions and various controller modes (US modes) that provide different I/O computing functions. These modes are designed to support their respective control applications. From these choices, you can choose one that best meets your application needs.

In some control applications, however, you may want to execute special computations based upon specific input data or have a contact output of a specific data item in a specific control sequence. To be able to meet these needs, the US1000 controller provides a separate controller mode with which you can freely program your own computations. Computing functions available in these modes are referred to as custom computations.

Custom computations allow you to perform a variety of calculations based on input and output signals. These calculations include not only the four arithmetic operations and logical operations but also tensegment linear approximations, temperature and humidity computations, temperature-based correction coefficient computations, pressure-based correction coefficient computations, and so on.

For example, you can use the four arithmetic operations to apply the desired type of correction to input signals, or use a logical operation to program a sequencing process that works between input and output contacts.

Custom computations are configured using the given methods of block connection, as shown in Figures 1.1.2 and 1.1.3.

Chapter 1 Overview

When custom computations are in use, you can also freely configure the operation displays of the

US1000 controller to suit your desired view. This function is designed so that you can choose from 1 the preset menus the types of data items, the sequence in which the data items are shown, and the

conditions required to show them on the PV and SV digital displays of the US1000 controller. The displays thus configured are referred to as custom displays.

Normally, the term “custom computing function” is used to include both the custom computation and custom display functions.

Chapter 4 Basic Operations for Configuring Custom Computations and Relevant Explanations

4.Basic Operations for Configuring Custom Computations and Relevant Explanations

This chapter explains the procedure for configuring custom computations.
For details on the preparatory work for using the LL1200 tool, see Chapter 2, "Setup." Likewise, for
an overview of the procedure for configuring custom computations and displays, see Chapter 3,
"Using the LL1200 Tool."
Also refer to Chapter 4, "List of Computation Modules and Their Functions," in the Model LL1200		4
PC-based Custom Computation Building Tool-User's Reference instruction manual (IM 5G1A11-02E),
for detailed specifications of the computation modules.
In order to configure custom computations, you must follow the steps shown below.
●Step 1: Choosing the Way Computations Are Configured ---------------------------	(Section 4.1)
●Step 2: Configuring Custom Computations in an Input Block -----------------------	(Section 4.2)
●Step 3: Configuring Custom Computations in an Output Block ---------------------	(Section 4.3)
●Step 4: Setting Ten-segment Linearizers 3 and 4 Parameters (as necessary)- (Section 4.4)
●Step 5: Setting USER Parameters (as necessary) -------------------------------------	(Section 4.5)
When you are finished with these steps, download the configured custom computations to the US1000
controller (see Section 8.2). Then, verify their performance by means of custom computation monitor-
ing (see Chapter 11).

4.1Step 1: Choosing the Way Computations Are Configured

When you start the LL1200 tool, a dialog box appears as shown in Figure 4.1.1.

Figure 4.1.1 [Tool Selection] Dialog Box

Click the <Custom Computation Building Tool> option button, and then the <OK> button. The [New/ Modification] dialog box (Figure 4.1.2) appears.

Chapter 4 Basic Operations for Configuring Custom Computations and Relevant Explanations

There are four ways of configuring custom computations, as described below. Choose one of these four ways.

TIP

If you are configuring custom computations for the first time, it is advisable that you use a sample file.

For your information, Section 4.2, “Step 2: Configuring Custom Computations in an Input Block,” uses the sample file (USM01.1SC) for single-loop control to explain all the operating procedures that follow that particular section.

If you are configuring a custom computation from scratch, choose <New File>.

Click the <New File> option button, then the <OK> button. The [Specify Suffix Code and Controller Type] dialog box (Figure 4.1.3) appears.

If you are configuring a custom computation using a user file, choose <Open User File>. Click the <Open User File> option button, and then the <OK> button. The [Open User File] dialog box (Figure 4.1.4) appears.

If you are configuring a custom computation using a sample file, choose <Open Sample File>. Click the <Open Sample File> option button, and then the <OK> button. The [Open Sample File] dialog box (Figure 4.1.5) appears.

If you are configuring a custom computation by uploading data from the US1000 controller, choose <Upload from US1000 Controller>.

Click the <Upload from US1000 Controller> option button, and then the <OK> button. The [Upload from US1000 Controller] dialog box (Figure 4.1.6) appears.

NOTE

When uploading custom computation information from US1000 controller, set the controller mode (US mode) to “21.”

■ [Specify Suffix Code and Controller Type] Dialog Box

If you choose <New File> in the [New/Modification] dialog box (Figure 4.1.2), the [Specify Suffix Code and Controller Type] dialog box (Figure 4.1.3) appears. This dialog box also appears if you choose <Open Sample File>.

In the [Specify Suffix Code and Controller Type] dialog box, click the <OK> button. The [Custom Computation Configuration Menu] dialog box (Figure 4.1.7) appears.

Figure 4.1.3 [Specify Suffix Code and Controller Type] Dialog Box

● Explanation of the [Specify Suffix Code and Controller Type] Option

The suffix code must be specified because the code needs to be verified when you download information on the custom computations you configured using the LL1200 tool, to the US1000 controller. Likewise, the controller type must be specified because you must decide upon the desired operating conditions for the US1000 controller.

Controller Type	Criteria for Choice

Single-loop type	The following are used:
	• One PID computation
	• Switching among loop-1 CAS, AUTO and MAN modes
	• Switching between RUN/STOP modes
	• Switching between the loop-1 Open/Close modes

Dual-loop type	The following are used:
	• Two PID computations
	• Switching among loop-1 CAS, AUTO and MAN modes
	• Switching among loop-2 CAS, AUTO and MAN modes
	• Switching between RUN/STOP modes
	• Switching between the loop-1 Open/Close modes
	• Switching between the loop-2 Open/Close modes

Cascade type	The following are used:
	• Two PID computations
	• Switching between RUN/STOP modes
	• Switching among the loop-1 CAS, AUTO and MAN modes
	• Switching between the loop-2 Open/Close modes

NOTE

Data cannot be downloaded to US1000 controllers whose suffix codes do not match the one specified. Check the suffix and optional suffix codes of the US1000 controller to which you download data.
