5.7.2.2 Topic Configuration
Figure 84: FINS IO server topic configuration
Three (3) topics can be used for the IO Server. These topics are used to give a common property to a group of FINS Tags like:
• Enable/Disable
• Protocol
• Global Device Address
• Polling Rate
Serial FINS network
Source Network Address (SNA) filled in a FINS request message originating from
the eWON and sent out on the serial interface.
Serial FINS node
Source Node Address (SA1) filled in a FINS request message originating from the
eWON and sent out on the serial interface. It uniquely identifies the eWON on the
serial network.
Topic configuration item Description
Topic enabled Enables or disables the polling of all the Tags in the topic.
Protocol
Protocol used for the tags belonging to this topic: FINS Serial, FINS UDP, FINS
TCP.
Global Device Address
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 names must be refreshed every second - typically for
digital input - and other every minute - typically: temperature-.
