Does MQTT Transmission Module have legacy protocols pre-installed such as DNP3.0 and Modbus, etc. to get the data from legacy device as poll/response in native protocol? Or still need to install the driver module to the specific legacy protocols?
The MQTT modules are totally separate from Ignition drivers. Transmission allows you to expose whatever tags you have configured on a gateway as MQTT topics - you still need to have those tags available, which means that you must have the requisite drivers installed.
With that cleared the topic. Thanks @PGriffith
I have another question @PGriffith. How about the mqtt edge Gateway sparkplug? Does it have the legacy communication protocol drivers such as modbus, dnp3, etc. pre-installed?
