OPC UA (Unified Architecture) is the next generation of OPC, featuring cross-platform interoperability, high security, and proven reliability. Developed by the OPC Foundation, it is a machine to machine communication protocol for the industrial automation industry and retains all the core functions of OPC, effectively reducing the cost of system integration and allowing for data…
Tech Note 5119, “Using Ignition MQTT Engine with Maple Systems HMIs” provides set-by-step instructions on how to setup the Ignition MQTT Engine, custom topics, and JSON payloads. The Tech Note assumes that the user already has the Ignition platform installed along with the MQTT Engine and MQTT Distributor (or other MQTT Server infrastructure). For instructions…
The end user of the data. This can range from a high-end ERP management program that tracks information for control and data analytics, to a website that simply displays real-time operational facility data, and anything in between. A fundamental advantage of MQTT is that data is sent to a central “broker” instead of being directly…
cMT3000 series HMIs come with OPC UA Server and Client functionality built-in. cMT2000 series have only Client functionality, not Server. cMT-SVR-200 & cMT-SVR-202 are the only product that require an additional license to be purchased for OPC UA Client and Server functionality.
Tech Note 5111, “MQTT Set Up,” walks through the steps necessary to configure a Maple Systems HMI as an edge gateway for an MQTT network. There are 4 main tasks that are addressed in the tech note: A project will be created that enables the HMI to act as an MQTT publisher. HMI memory addresses…
