Fibre Optics Communication

By using RS485-to-Fiber Optics converters, you can use the M-series PLCs as remote I/O boards via Optical Fiber!  This allows the communication cable to be laid across  open field where lightning risk can cause severe damage to copper wire based communication links. On request by a customer we tested one such converter made by R.E. Smith (www.rs485.com, model FC485) as shown in the following diagram:

The plan is to have a master PLC collect data from the 20 plus slave PLCs in the plant floor and the data will become available to the corporate intranet for real-time production reporting and analysis via the corporate Intranet.  However, the customer requires that the master PLC be housed in the enterprise server room to acquire data from the 20 slave PLCs on the plant floor. The server room and the plant are in two separate buildings with a car park in between and the company is located in a tornado country with multiple lightning strikes every year. Optical fiber is the only feasible means of communication. We tested the above setup and it works flawless and the customer now has a reliable, standalone master PLC automatically collect production data and delivered to the management via the web browser.
