Getting Started with CX-Server Lite

When Customer Services need to be contacted, keep the following details to hand. A clear and concise description of the problem is required, together with the exact text of any error messages.

Note:

Use the About dialog to obtain the version number of the application.

Objects Overview

CX-Server Communications Control

This control provides a seamless interface between the CX-Server Lite host application (Excel,

Visual Basic) and Omron’s communication software, CX-Server. Note that the control is only visible when the host application is in the Design mode.

The Properties dialog enables you to select the project you wish to open. Clicking the

Open…

button will open the Open Project dialog allowing you to navigate to the appropriate file.

Clicking the Edit Project button opens the CX-Server Project Editor dialog. This dialog is supported by CX-Server and follows the standard Windows Explorer format. The left hand pane shows the tree structure for the project. By expanding the tree the associated PLCs and

Points etc. can be reviewed and edited as necessary. New PLCs and points can be added by right clicking in the right hand pane and selecting

New

from the menu. Consult the associated help file for more detailed information on editing.

Temperature controller devices are supported in this version of CX-Server LITE. See Script

Interface support and Appendix C for detailed information regarding the available functionality.

7 Segment

The 7 Segment control displays a value in Binary, Decimal or Hexadecimal format. Leading zeros and unused segments can be hidden. The colour of the segments and the display background can be set independently. The 7 Segment control cannot be used to set a value.

Data Logging

The Data Logging control provides logging and trending functionality through use of the Data

Log Viewer components currently used by other Omron software packages including

CX-Supervisor and SYS-Config. The control is configured in design-mode to log data items and is controlled in runtime-mode using script commands. See the on-line help for further details regarding the script interface.

Display

The Display displays an analogue or text value. The Display only displays a value i.e. you cannot set a value using this display.

LED Indicator

The LED functions as a coloured on/off indicator. The colour of the indicator and the display background can be set independently while its shape can be round or square. In the off state, the chosen indicator colour is dimmed.

Linear Gauge

The Linear Gauge displays an analogue value by filling a rectangle to represent the actual value as a proportion of its expected maximum. The rectangle can be filled from bottom to top

(like a thermometer) or from left to right (like a progress complete bar). There is also a configurable scale, enabling intermediate values to be estimated. The Linear gauge will only display a value, you cannot set a value with this gauge.

Linker

This control gives the ability to link COTS (commercial off the shelf) ActiveX components to any of the Omron communications controls, e.g. the CX-Server communications control. The control is configured in design-mode to select the ActiveX component (e.g. a Microsoft Forms V2.0 check box control) to which the control will link at runtime. In runtime mode data will be read from and written to the selected PLC item and the selected ActiveX component.

Note: In this version, the linker cannot link text points or array points only single element points.

Rotational Gauge

The Rotational Gauge displays an analogue value, similar to a speedometer. An indicator needle rotates according to the value. There is a configurable scale, enabling intermediate values to be estimated. The Rotational gauge will only displays a value, you cannot set a value with this gauge.

Rotary Knob

The Rotary Knob allows you to set an analogue value, similar to a volume knob. You can rotate the knob, e.g. by clicking and dragging the mouse, to set the pointer to a new position. There is a configurable scale, enabling intermediate values to be estimated. The pointer always reflects the current value e.g. on start-up, and will change position in response to an external influence.

Toggle

The Toggle allows you to toggle a Boolean bit between its ‘On’ and ‘Off’ state. This is as a switch that can be clicked to change its state. The current state is shown by the position of the switch. The switch position also reflects the current value e.g. on start-up, and will change position in response to an external influence.

Timer

The timer enables you to run a set of instructions repeatedly at regular intervals.

Thumbwheel

The Thumbwheel provides a set of input controls, similar to a hardware Thumbwheel Switch.

By clicking minus and plus buttons, the various input digits can be set. There are two modes of operation; Commit and Direct. When the optional

Commit

button is enabled, digit values may be edited freely. The PLC will not receive an updated value until the Commit button is pressed.

In

direct mode

[without the optional Commit button] changes to digit values are sent direct to

the PLC as they occur. Floating point is supported, and integer values can be represented in both decimal and hexadecimal.
