Is JSON supported in MQTT / Ignition?
Yes, JSON Advanced setting has been added for MQTT Topic Publisher on cMT Series models. Aside from being compatible with the existing simple JSON format, this function allows users to define JSON format with more flexible structure tailored to the cloud device they use.

With this function added, data transferred to the cloud can be generated in the required format without the need for an extra conversion tool, realizing integration with diverse cloud services, thereby turning conventional PLCs into IIoT smart devices. Furthermore, users can simply configure the settings via an intuitive graphical user interface, which eliminates the need for writing JSON codes in order to define the data structures.
