Of the three, only the ThingWorx agent uses WebSockets. Q: Do we need to poll every X amount of time or are you using WebSockets?Ī: The MQTT, ThingWorx, and HTTP client agents push/publish messages at a specific interval.

Q: What is the method for refreshing data?Ī: Sample rates are configured as a property of each tag added to gateway agents. Q: What is the best way to configure security?Ī: Utilize username and password authentication as well as SSL/TLS when available. Q: Are store and forward built into the MQTT or REST clients in case you lose connection to the Cloud?Ī: There is currently a fixed buffer built in (10,000 updates buffered per agent), but we are looking to enhance this to be more robust. Q: Is it possible to use the IoT Gateway's ThingWorx agent type to write to a PLC?Ī: No, the ThingWorx agent does not support writes to PLCs however, the ThingWorx Native Client Interface support does (and is available in KEPServerEX version 5.21 and above). Q: Does the IoT Gateway support HTTPS (secure HTTP)?Ī: Yes, both the REST Client and REST Server agent types support HTTPS.

Q: Can you explain what other transfer protocols are supported besides MQTT?Ī: The IoT Gateway also supports HTTP (RESTful client and server).Ī: Yes, our MQTT Client agent uses SSL/TLS for encryption. With topics spanning everything from IoT Gateway agent features to data buffering and vendor-specific connectivity, I thought it would be helpful to re-visit and share them. But with so much to cover during the webinar, I didn't have time to answer each question that was asked. These use cases demonstrate how real-world companies are solving their industrial connectivity challenges and improving traceability, visibility, and product quality with industrial IoT solutions.

Industrial data for Cloud and Big Data systems.

Mobile and web interfaces for manufacturing systems.

Industrial data over web services for manufacturing execution.

After describing what the industrial IoT means to Kepware, I explored three real-world use cases by Kepware customers: Last month, I presented a one-hour webinar (seen below) on the industrial Internet of Things (IoT).
