One Node Distributes I/O

Jan. 1, 2004
The Telemecanique Advantys STB is a modular distributed input/output system that integrates I/O modules, power distribution and device integration into a single design.

With the system, one fieldbus node can distribute I/O across an entire machine or process. Communication network interface modules allow the Advantys STB to interface with standard fieldbuses, including Modbus TCP/IP. The system can be remotely monitored through a built-in Ethernet Web server, or locally monitored via an embedded serial port. The power distribution modules distribute field power across two, isolated buses—a sensor bus, for input modules, and an actuator bus, for output modules. A reflex functionality enables the STB to perform local-level, high-speed logic solving, independent of the PLC master.
