Remote Communication Solution for Gas Detector (Part 1)
As shown in the figure, the site is networked according to the bus based communication method,RS485The signal is transmitted to the optical transceiver and converted into an optical signal, which is then transmitted using optical fibers. At the receiving end, the optical transceiver converts the optical signal intoRS485Signal, to the computerPLCWaiting for the device to receive.
