6.5.2.2 Topic configuration
Figure 51: XWAY-UNITELWAY topics configuration
Three topics can be used for the IO Server. These topics are used to give a common property to a group of UNITE Tags such as:
• Enable/Disable
• Poll rate
• Device address
Topic configuration item Description
Topic enabled Enables or disable polling of al the Tags in the topic.
Device Address
This device address is a global parameter for all the Tags of the topic.
See below for the Device Address syntax. If an address is specified here,
it will replace (overload) the address defined Tag by Tag.
Poll rate
Defines the refresh rate of the Tag name. In a complex application, we can
imagine that some Tag name must be refreshed every second –
typically for digital input - and other every minute – typically: temperature-.
