Chapter 3

Data Values Upload/Download

Introduction

In this chapter you will learn to use the PanelView Plus application that you created in the previous chapter to interact with the Micro800 controller global variables in Connected Components Workbench software.

Using Data Values Upload/Download

The Data Values Upload/Download feature allows you upload live logical values of variables that may have been changed by the operator in PanelView Plus (or program logic) and save them in your project as project values. Then optionally at download, the project values can be re-downloaded. The Data Values Upload/Download feature applies to both local and global variables, including instances of function blocks.

In Connected Components Workbench, when not monitoring the live logical values of variables, Connected Components Workbench will display a column named Project Values. Project Values are logical values which are saved in the project.

ATTENTION: If power is lost during the upload or download process, all user data will be lost.


Chapter 3 Data Values Upload/Download

In Connected Components Workbench, when in Debug mode and monitoring the live values of variables, Connected Components Workbench will display a column named Logical Values.

Note that the Initial Value column is shown in both non-debug mode and in debug mode. When a project is downloaded and both the Initial Value and Project Value are configured, then Initial Value has precedence and will be downloaded in to the live Logical Value.

Priority of Logical Values When Downloading

Project Value Initial Value Logical Value after Download

Exists Blank Project Value

Blank Exists Initial Value

Exists Exists Initial Value


Data Values Upload/Download Chapter 3

To begin, open the sample Micro820 controller project in Connected Components Workbench.

Editing Array Data Types

If your global variables contain array data types, the way it is displayed in Connected Components Workbench and Microsoft Excel is different. See the examples below.

Array Data Type in Connected Components Workbench

Array Data Type in Microsoft Excel

Note how the Initial Value of the array indexes are displayed in the two examples shown above. If multiple indexes have the same Initial Value, they are grouped together in the format "x(y)" where "x" is the number of indexes and "y" is the Initial Value.

Data Types

Supported Data Types The following data types are supported.

When you see the controller variables in PanelView Plus, it will be shown as described in the table below.

Structured data types are NOT supported.

When Using Array Variables

A variable can be created as an array of data types and up to three dimensions are supported. The following rules must be observed when using an array of data types.

1. An array cannot be a Boolean data type.

2. An array cannot be an Array data type.

Data Type Hex Value Dec Value Description

BOOL 0xC1 193 Logical Boolean with values TRUE(1) and FALSE(0)

SINT 0xC2 194 Signed 8-bit integer value.

INT 0xC3 195 Signed 16-bit integer value.

DINT 0xC4 196 Signed 32-bit integer value.

LINT(1)

(1) LINT data types are not fully supported in PanelView Plus. When using LINT tags, values that are less than 53 bits are not displayed correctly or may appear wireframed on the display client.

0xC5 197 Signed 64-bit integer value.

USINT 0xC6 198 Unsigned 8-bit integer value.

UINT 0xC7 199 Unsigned 16-bit integer value.

UDINT 0xC8 200 Unsigned 32-bit integer value.

ULINT 0xC9 201 Unsigned 64-bit integer value.

REAL 0xCA 202 32-bit floating point value.

LREAL 0xCB 203 64-bit floating point value.

STRING(2)

(2) The STRING data type does not support Unicode.

0xDA 218 Character string.

Appendix A Data Types

3. The starting index of the array must be zero.

An example of an array variable in Connected Components Workbench is shown below. The index of the array is shown in square brackets.

When assigning a tag to an object in your PanelView Plus application, you can assign a specific index of an array by doing the following:

1. In the Tag Browser window, select the Online -> Array_Data_Type folder.A list of tags of the array and each of its index is displayed.

2. Select the tag of the array with the desired index, then click OK.
