PointIO is a hardware solution from Allen Bradley that allows a PLC to extend input and output reach to remote locations over EtherNet, DeviceNet, ControlNet, and PROFIBUS. This family of hardware is commonly used in distributed systems and is paired with CompactLogix or ControlLogix controllers that would otherwise be costly to wire to remote locations. PointIO offers a wide range of modules and is highly customizable to fit the needs of the application. Furthermore, it’s easy to install and troubleshoot. A module can be replaced in a running system without the need to program, re-address, or additional setup after the system has been programmed.
