S7-200Smart PLC to MQTT Cloud Platform used in Water Pump Station IoT Solution
In many water supply departments, they usually use Siemens S7-200 as the controller, but now they need to realize remote control and connect to various IoT cloud platforms. Therefore, it is necessary to realize the data collection of S7-200Smart through PLC IoT Gateway BL102, and then access to the IoT cloud platform in MQTT Json format or OPC UA.
The PLC IoT gateway BL102 can realize PLC data collection and convert it to MQTT protocol or OPC UA protocol at the same time. Users do not need to care about protocol conversion issues. As shown below:
S7-200Smart supports serial communication. Therefore, the BL102 serial port is used to connect to the S7-200Smart. At the same time, it is connected to the HMI through the BL102 Ethernet interface as a local display control. At the same time, it is connected to the cloud platform through a 4G network or Ethernet. The schematic diagram is as follows :
In this way, the remote monitoring of the pumping station of the water supply enterprise can be realized quickly, efficiently, and at low cost.
Moreover,the PLC IOT Gateway BL102 supports lots of PLC, see below:
