Client General Properties

These properties apply to the Vision Client in general.

Timezone Behavior

The Vision Client can emulate any timezone. By default, it will appear to be in the same timezone as the Gateway. This has the effect of all clients behaving the same, regardless of the timezone setting on the Client's host operating system. Depending on your project's requirements, this may not be optimal. You may have the Client use the host's timezone by choosing the "Client Timezone" option, or you may specify an explicit timezone for all Clients to emulate.

Publish Mode

This setting affects how clients receive updates when the project is saved. The default is Notify, which means that all running Clients will display a yellow information bar at the top of their display that notifies the operator that an update is available. The update will be installed when the operator clicks on the yellow bar. You may choose Push mode to have updates automatically pushed to all running clients with no operator interaction. This is often desirable when a client is running in a situation where keyword and mouse access is inconvenient, such as in a large overhead display.

Touch Screen

All clients can operate in touch-screen mode. When in this mode, clicking on numeric and text entry boxes will pop up on-screen keyboards that can be used for data entry. By enabling touch-screen mode, an operator is given the opportunity to activate the mode on the startup screen. You have the opportunity to control whether or not clients start up with touch-screen mode active by default or not as well. These settings are helpful for mixed-use projects, i.e. those that are launched on both touch-screen devices and traditional computers and laptops.

Data - Tag History Cache

The clients normally maintain a cache of data retrieved from SQLTags History, improving repeat operations on graphs and tables. When this option is disabled, no data is cached, and the full queries execute against the gateway each time data is required.
