Shearing lines interference, or where both increased transmission ranges and speeds are involved at the same time, fiber optic cables can be used. Data communication to peripheral equipment such as coil lines, coil stock thickness gauges or coil lubrication systems is performed via the I/O interface of the PLC. Between the industrial PC and the PLC, data communication is implemented via an active serial interface with 20 mA. For data communication with a higher-level computer system, an additional serial interface is available in the industrial PC.
