5.13.Interpreting Analog, Text and LED controls

These controls are part of the Advanced Feature Pack and are ordered separately from part 8706-01.

The example page below has an image and on its borders are two analog, two text and two LED controls. This page is not part of the template project provided with the LANServer. It was created to illustrate the Analog, Text and LED Controls.

Flashing controls indicate a problem. Flashing means, rapidly toggling from one state to another. In the case of Text controls this means flashing between the ‘on’ and ‘off’ text. In the case of LED controls this means flashing between the ‘on’ and ‘off’ images and in the case of an Analog control, flashing means toggling between a ‘-1’ and ‘?’

Each control is configured by specifying the name of a Data Array and an offset into that Data Array. If the Data Array does not exist or if he offset is invalid then the controls will ‘flash’

If the Browser is ‘offline’ from the LANServer then the controls will flash. Offline means, disconnected or that cookies have expired.
