OPC Classic vs MQTT
Developers should learn OPC Classic when working on industrial automation, manufacturing execution systems (MES), or supervisory control and data acquisition (SCADA) projects that require integration of legacy equipment or systems relying on Windows-based communication meets developers should learn mqtt when building iot systems, such as smart home devices, industrial automation, or remote monitoring, where resource-constrained sensors and actuators need to communicate efficiently over networks with limited bandwidth. Here's our take.
OPC Classic
Developers should learn OPC Classic when working on industrial automation, manufacturing execution systems (MES), or supervisory control and data acquisition (SCADA) projects that require integration of legacy equipment or systems relying on Windows-based communication
OPC Classic
Nice PickDevelopers should learn OPC Classic when working on industrial automation, manufacturing execution systems (MES), or supervisory control and data acquisition (SCADA) projects that require integration of legacy equipment or systems relying on Windows-based communication
Pros
- +It is essential for scenarios involving real-time monitoring, data logging, and control of industrial processes where interoperability between diverse devices from multiple vendors is critical, though it is being gradually replaced by OPC UA in modern implementations
- +Related to: opc-ua, industrial-automation
Cons
- -Specific tradeoffs depend on your use case
MQTT
Developers should learn MQTT when building IoT systems, such as smart home devices, industrial automation, or remote monitoring, where resource-constrained sensors and actuators need to communicate efficiently over networks with limited bandwidth
Pros
- +It is ideal for scenarios requiring real-time data exchange, scalability, and low power consumption, as its lightweight design reduces network traffic and processing demands compared to alternatives like HTTP
- +Related to: iot-communication, publish-subscribe-pattern
Cons
- -Specific tradeoffs depend on your use case
The Verdict
These tools serve different purposes. OPC Classic is a platform while MQTT is a protocol. We picked OPC Classic based on overall popularity, but your choice depends on what you're building.
Based on overall popularity. OPC Classic is more widely used, but MQTT excels in its own space.
