In the “Message Type” field, select the “Channel Data” to prepare a
Publish Message with the power data or I/O channel value. Based on
the “Channel Data” interface, the user can select a specific power data
(or I/O channel value) or “All” power data (and I/O channel values)
for the Publish Message. If the user selects a specific channel, it
means the specific power data (or I/O channel value) of the module
will be bound with the Publish Message. If user select “All” channels,
it mean all power data (and I/O channel values) of the module will be
added in the Publish Message List. If the user click the "JSON
Format" check box, the content of the Publish Message will be
packaged in JSON format; if the “JSON” is not selected, the content
of the Publish Message will only include the I/O channel value (For
the I/O Channel information in JSON Format, please refer to
Appendix VIII for more details.). After completing the “Channel
Data” setting, the system will automatically generate the default Topic
content in the “Topic” field. User can modify the content of the
“Topic” field if require. If the "Use Prefix" checkbox is enabled, the
string in the “Topic Prefix” field will be used as the prefix of the
Publish Topic.
