Product Overview
The MQTT Client driver works in conjunction with KEPServerEX to provide a seamless, secure, and reliable data exchange between devices that utilize the MQTT protocol and client applications.
MQTT is a lightweight message protocol that connects to a wide variety of industrial Internet of Things (IoT) and industrial automation devices. MQTT is often used to connect sensor networks and is increasingly embedded on next generation industrial automation devices. In many scenarios, MQTT transmits data from these devices to the Cloud.
The MQTT Client driver is a user-friendly out-of-the-box MQTT to OPC UA translator. It securely accesses otherwise siloed data and transmits it to KEPServerEX. Users can then integrate this data with data collected from traditional industrial automation assets—such as PLCs, sensors, and databases—to create a single source of consolidated plant floor data.

Release Notes
6.5.829.0
6/19/2018
- Added Automatic Tag Generation for subscribed topics, allowing users to create tags in the server with minimal setup.
- Added UTF-16 support for JSON payloads, allowing parsing of both UTF-8 and UTF-16 JSON payloads.
- Added support for “NULL” values in the JSON payload.
- Added support for all characters in the Client ID.
- Added unsolicited data updates for clients that support it.
- The total number of channels is now limited to 60.
6.4.405.0
6/11/2018
- Allow '@' to be used in the Client ID.
6.4.321.0
12/13/2017
- Initial release of the MQTT Client driver with the capability to connect to an MQTT broker and a specified Topic. The driver parses any valid JSON messages that are published to the Topic and update tags based on that data. This is a read only driver; it is unable to publish data to a Broker. The driver is configured in the Connectivity node of the Project Tree.

What Is a Driver?
KEPServerEX is more than an
OPC server—it's a connectivity platform for industrial automation and IoT. Simply download KEPServerEX, and then select from Kepware's library of more than 150 device drivers, client drivers, and advanced plug-ins to fit the communication requirements unique to your industrial control system.
A driver is a software component that enables KEPServerEX to meet the connectivity requirements of a specific device, system, or other data source. The driver handles all proprietary communications to the data source for KEPServerEX; the client interfaces handle all supported OPC, proprietary, and open standards connectivity to applications that monitor or control the devices.
Drivers may be licensed individually or in suites. Additional drivers can be licensed on demand as connectivity needs evolve.
