7.6 Using ViewRTU
By using ViewRTU, the user is able to define or modify sub-programs called Software Blocks.
Software blocks are used to configure the Tank Gate Interface.
Note Refer to the Tank Gate Interface Software Blocks chapter for specific examples. The
chapter provides a description of the parameters for each point as well as examples of the
connections to other points.
Tank Gate Interface software blocks are functions that the user can configure to perform various
tasks. Software Blocks are available to scan data from a slave device, control a pump, serve data
to other Host systems or perform calculations. Each function type contains both the code and
data necessary to perform the function. Software Blocks are identified by their type (example:
AI, DI, LJ2000 and PUMP). Points are individual instances of software blocks. Each point must be
added and then configured. Adding a point makes the point available for configuration. All
defined points appear in both the Point Icon Selection area and the Spreadsheet Summary in the
main window.
Configuring the point involves entering configuration parameters. In some cases, connections
to other points are required in order to perform a task. Creating connections involves setting
references to allow data to be transferred between points.
7.6.1 Overview
An outline of the section is listed below:
Configuring Single Points
This section describes the method used to configure individual points including:
•
Adding a Point
•
This section describes how to define a point from the Main window.
•
Entering Point Data
•
This section describes how to enter the point’s parameters. Parameters are entered from
the Edit Point Window.
•
Modifying Strap Tables
•
This section describes how to modify strap tables in ViewRTU.
Configuring Multiple Points
This section describes the spreadsheet mode. The principles involved in point configuration are
the same, but the methods are slightly different.
•
Adding Multiple Points
•
This section describes how to define a point from either the Main window or the
Spreadsheet Mode window.
•
Entering Point Data
•
This section describes how to enter a point’s parameters. Parameters are entered from the
Spreadsheet Mode window.
Creating and Editing Connections
This section describes how to create connections between various points. Points may be used
to retrieve and/or deliver data from other points.
