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).

3. T ypes and Ranges of Computation Data

This chapter explains the types of computation data used in the input and output blocks, and their ranges. When you configure custom computations, you must make sure they comply with the specific types of computation data, such as range data, scale data and percentage-type data, which are fed to/from the input and output blocks. Y ou can verify the computation data types in this chapter.

Figure 3.1 below shows an example of data flow where data taken in through analog input 1 (AIN1) is fed first to the EU Range Conversion (EUCONV) module and then the Tensegment Linearizer 1 (PLINE1) module, for computation. The resulting data is then passed to the PVIN.1 signal of the loop 1 control-and-computing section.

If the AIN1 analog input is a thermocouple (TC) input or a resistance temperature detector (RTD) input, the input data has a value ranging from the minimum value of the analog input 1 range (RL) to the maximum value of the analog input 1 range (RH), which corresponds to the internal data range from 0 to 30000.

If AIN1 is a voltage input, the input data has a value ranging from the minimum value of the analog input 1 scale (SL) to the maximum value of the analog input 1 scale (SH), which corresponds to the internal data range from 0 to 30000.

The PVIN.1 signal has a value ranging from 0 to 30000, which is an internal value obtained by converting a value ranging from the minimum value of the PV1 range (P.RL1) to the maximum value of the PV1 range (P.RH1).

3-1

Input signal fed to the input block: If the AIN1 analog input is a TC input or an RTD input, it takes a data value ranging from RL1 to RH1. If AIN1 is a voltage input, it takes a data value ranging from SL to SH (setup parameters).

Module’s output data: This register has a data value converted to within the range of the PVIN.1, which is set by the P2 parameter of the EUCONV module.

Parameter settings for the computation module: The EUCONV module automatically matches the data types according to the settings of the P1 and P2 parameters. P1 = 0: the module obtains data from analog input 1(AIN1). P2 = 0: the module passes the data to PVIN.1 (to loop-1 control computation).

Output signal fed from the input block: This is a data value ranging from 0 to 30000 that corresponds to the P.RL1 to P.RH1 range, in which the data should be passed to the controland-computing section.

3.1 T ypes of Computation Data

The types of computation data used for custom computations are classified in the following table.

The table also summarizes the displayed values and the corresponding internal values, hereinafter referred to as computation data. See the next section for the data type of the I/O data of the input and output blocks.

Integer data is normally used to configure your own custom computations. It is signed 2byte (16 bits) data, with a value limited to the ±30000 range. Y ou can use data of up to 4byte (32 bits) data with a plus or minus sign, however, with some of the computation modules such as those for four arithmetic operations. For example, these modules can have the result of multiplying 2-byte data by 2-byte data as 4-byte data. In that case, the result is stored in two D registers (e.g., the MO1L register [lower-order word] and the MO1H register [higher-order word]).

4. List of Computation Modules and Their Functions

This chapter explains the function specifications of each computation module. A list of the modules is presented first, and then the functions of each module are described.

The following paragraphs explain some of the specifications that appear throughout this chapter.

■ IN1 to IN8, P1 to P4, OUT

IN1 to IN8 represent the inputs of each computation module, P1 to P4 are the module parameters and OUT is the output. The following symbols are used to indicate the size of data that have functional assignments within each module.

: 4-byte data (two words) : 2-byte data (one word) : Flag data (0 or 1)

4-1

NOTE

Some computation modules have their “OUT” marked with the symbol “⫻” which indicates that they themselves do not output any data. Output registers of such modules store the same data as that of their immediately preceding (in the execution order) module.

■ Work Area

Some computation modules require a “work area,” whose size is indicated with a number . Y ou can use work areas up to a total size of 240. You cannot register computation modules that use work areas exceeding 240.

■ Limitation on Use

Computation modules with limited usage are given a number that indicates the number of times it can be used.

4.1 How to Hold Outputs at Power Failure and

Recovery Using Custom Computation

■ Example: Holding the Output V alue of SUM Module

Step 1) Save the output data value of a module into D1041 to D1050 (for word data) or

D1051 to D1060 (for long word data) by using the No. 78 Data Save module.

IN1 of DA TASAVE: Input of DAT ASAVE. In this example, input the output of SUM. P1 of DA TASAVE: Specifies the register where the data is saved. Since SUM outputs

long word data, specify D1051 (LDA TA1L).

P2 of DA TASAVE: Always set to “1” (write-enabled).

Step 2) At power on, use the saved data as the initial value.

IN2 of SUM: Specify D1050 (LDA TA1L) for an initial value of SUM. P1 of SUM: Specify I0672 (PON: power-on flag, set 5672) as the initialization flag.

NOTE

Since the Sum module (No. 30) cannot have an initial value when addition is specified, its output will be reset to 0. When subtraction is specified, an initial value lower than its output value will be 0.

The module sets IN4 in the decremental counter if IN2 = 1, where OUT = initial value (irrelevant of the IN1 value). The output is enabled if IN1 = 1, and the module counts down if IN3 changes (from 0 to 1 or from 1 to 0). The output is disabled if IN1 = 0 and does not change for as long as IN1 = 0, even if IN3 changes.

If P1 = 0, the decremental counter stops when it reaches 0. If P1 = 1, the initial value is set in the decremental counter when it reaches 0, resulting in a change in the initialization flag; which allows the counter to resume operation.

[TIP]

[Detailed Explanation]

In normal application, the analog input (AIN) undergoes a specific type of computational process as necessary, while coupled with the process variable input (PVIN). Assume that AIN1 is coupled with PVIN.1, and each pair of maximum and minimum values for these inputs is set to RH1 and RL1 (or SH1 and SL1 if the input is DC voltage), and P.RH1 and P.RL1. If both of these pairs are set to the same range, the EUCONV module need not be used. If their ranges differ, the EUCONV module is placed between AIN1 and PVIN.1 so that conversion is carried out between the two different ranges in order to match the types of data. For example, assume that RH1 = 1000 °C and RL1 = 0 °C, and P.RH1 = 2000 °C and P.RL1 = 0 °C. A signal input to AIN1 as 1000 °C is regarded as 2000 °C at PVIN.1 if the EUCONV module is absent, resulting in incorrect processing. If the EUCONV module is set in place, conversion is carried out so the signal is regarded as 1000 °C at PVIN.1. To understand this more clearly, the process is explained using specific values of internal data. For AIN1 or PVIN.1, the module internally has a pair of upper and lower limits for the given range, and of which are set in whole numbers, e.g., (30000, 0). In the example discussed above, the data value of 1000 °C, which is the upper limit of AIN1's span, is handled as 30000 internally. In order for this value to be regarded as 1000 °C when AIN1 is coupled with PVIN.1, it must be converted to 15000. (Since the value "30000" is regarded as 2000 °C at PVIN.1, the value "15000" is equivalent to 1000 °C.) This process is carried out by the EUCONV module in actual applications.

Switching Between Two Inputs

[Computational Expression and Explanation]

The module calculates equations comprising IN1 and/or IN2 according to the given switching method, and then outputs the result.

P1 = 0 (zone switching):

If IN1 ⬉ P3, then OUTn = IN1, If P2 ⬉ IN1, then OUTn = IN2, If P3 < IN1 < P2, then OUTn = (1 - x)⫻IN1 + (x)⫻IN2, where, x = (IN1 - P3)/(P2 - OUT

P1 = 1 (switching based on upper limit):

If IN1 ⭌ P2, then OUTn = IN2, If IN1 < P2 - 150, then OUT = IN1. The module turns on the internal tracking flag when the input is switched.

P1 = 2 (switching based on flag):

If P4 = 0, then OUT = IN1, If P4 = 1, then OUT = IN2. The module turns on the internal tracking flag when the input is switched.

The internal tracking flag is referenced by the control and computation unit so that the output does not bump during switching. If tracking is performed on PV1 however, the output bumps when a switch is made using an external contact.

[TIP]

The SELECT2 module is used when the controller mode (UT mode) is loop control with PV switching (UT mode 6) or loop control with PV switching and two universal inputs (UT mode 14).

[Explanation]

The module determines the relative humidity from the dry- and wet-bulb temperatures and outputs it. Data range of OUT: 0.0 to 100.0 %RH

The modules adjust the range to that specified by the type of output data (P3). Example: If the range specified is 0.0 to 100.0, the range remains as is.

Computation accuracy: ±0.31 %RH Computing is possible only if Td and Tw are in the range from 0 °C to 100 °C and Td > Tw. If Td or Tw < 0 °C or if the resulting value of computation is negative, the relative humidity is 0 %RH. If Td or Tw > 100 °C and Td < Tw, the relative humidity is 100 %RH. The saturation vapor pressure complies with the JIS Z8806-1981 standard.

[Explanation]

The module replaces a value on the 0 to 30000 scale with a value on the 0 to 1 scale

order to extract the square root of that value. It then converts the result back to a

on the 0 to 30000 scale for output.
