Many industrial grade electronic devices – from temperature sensors, ground leakage detectors, aircons, gensets and other industrial equipments have the standard RS485 port, which allows access to data from these systems for further analysis. Typically these are used in a traditional wired environment.
Wireless RS 485 & data visualisation
RS 485 provides two way communication using scripts such as Node-RED which allow rules to be created based on threasholds. The data from RS 485 devices can be pushed on to an IOT edge gateway to provide shop floor data visualisation, which in turns helps the operational staff to take preventive action in the case of any malfunction.
However, it is seen that in many factories, the Rs- 485 ports are unused due to the need to wire them and access the data on to a central edge device. So, rather than attaching a USB or RS 232 converter, the wireless RS 485 module sends data over the air. Less of cabling, maintenance and troubleshooting.
RS485 is the most versatile communication standard in the standard series defined by the EIA, as it performs well on all four points. That is why this technology is currently a widely used communication interface in data acquisition and control applications where multiple nodes communicate with each other.
