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
6.7.2.3 Gateway Configuration
The following parameters can be modified:
Figure 56: FINS IO server gateway configuration
Topic configuration item Description
Topic enabled Enables or disables 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-.
Table 68: FINS IO server topic configuration fields
Server Port
Identifies the FINS UDP/TCP port used by the FINS service
(same port defined as well for UDP than TCP).
FINS TCP Server Node
EWON FINS server node address used during FINS TCP session establishment
(exchange of the FINS node address messages, and allocation of a FINS TCP
Client node if necessary).
Routing Entry 1..3
For each defined destination network, gives the matching relay destination node.
This is used to fill in the host link unit ID in the hostlink frame which encapsulates
the FINS message sent out on the serial interface.
