INTERBUS-S is a serial bus, master/slave fieldbus communication system that was developed by Phoenix Contact to transmit data between control systems (PCs, PLCs, VMEbus computers, robot controllers, etc.) and distributed I/O modules that communicate with sensors and actuators/switches. INTERBUS-S Remote Bus cable contains three twisted-pairs with a single, common shield for communications only, no power. Installation Remote Bus cable is similar to Remote Bus cable, except that it contains three additional conductors for supplying communications power (up to 4.5 amps) to various devices.
The system operates in an active ring topology (with branches) and consists of one master and up to 511 slave devices. Attainable speed is 500kbps or 2Mbps. Installation is accomplished with shielded twisted pair cables and 9-pole D-Subminiature connectors. Maximum cable length between two devices is 400m and up to 13km in total. Alternatively, fiber optic media can be used
INTERBUS-S is now integrated in PROFINET IO, together with PROFIBUS.
