5.15.2.2 Topic configuration
Figure 107: MITSUFX IOServer: 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 Mitsubishi Tags like:
• Enable/Disable
• Global Device Address
• Polling Rate
Table 121: MITSUFX IOServer: Topic configuration item definition
5.15.3 Tag name convention
The Item Name can contain the PLC address where the value is polled, or not. If the address is also specified at topic level, the address specified
at Tag level will be ignored.
Topic configuration item Description
Topic enabled Enables or disables polling of all the Tags in the topic.
Global Device Address
Select the type of Mitsubishi PLC to link. Available FX type are:
• FX
• FX0
• FX0N
• FX2N
• FX3U
There is no address (number) to add because the eWON is connected directly to
one PLC by its programming port.
If a device is specified here, it will replace (overload) the device-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-.
