Wireless RS 485 & data visualisation
Many industrial grade electronic devices – from temperature sensors, ground leakage detectors, aircons, gensets and other industrial equipments have the standard RS 485 port, which allows access to data from these systems for further analysis. Typically these are used in a traditional wired environment.
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.
Wireless RS 485 integrated sensor modules are now available from vendors such as Ripples IOT Pte ltd. These are wireless mesh network solutions which can connect multiple RS 485 enabled devices across the shop floor, to provide machine data that can be displayed at the control centre.
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 RS485 is currently a widely used communication interface in data acquisition and control applications where multiple nodes communicate with each other.
