The non-contact temperature measurement devices of Optris feature advanced interface concepts which allow an easy integration within networks and automatedsystems. The following technical note highlights the setup of thermal imagers via an RS485 module as well as of online infrared thermometers via PLC using PROFIBUS DP
Regarding PLC environments the PROFIBUS is generally accepted as one of the most used bus system. Concerning the production, process and building automation, the bus system represents an ideal, secure and fast communication exchange between the single bus partners and the control units.
The set up of the PROFIBUS network is almost the same every time. On the one side you can find the control unit, e.g. a SIMATIC S7 of SIEMENS – also called master system or active station. On the other site you can find the bus partners, the so called slaves – also know as passive stations. This can either be actors or sensors. All Optris infrared temperature sensors belong to the process or field communication – especially to the version&;PROFIBUS DP.
Integration of optris PI thermal imaging camera There is now an easy solution available to integrate the thermal imager optris PI into PLC environments. The solution is based on the great advantage of the master system to support the connectivity to other networks such as RS485. This enables the system setup covering long distances (up to 3 km) between the infrared camera and the PLC (illustration 1).
Generally, the optris PI thermal imager is connected to a PC, the imager’s software optris PI Connect displays Read More
