The PLC-5 controller is in the central position of the control system, integrates the existing and future systems through ethernet/ip, ControlNet and DeviceNet, and provides the interconnection between SLC 500, ControlLogix and Micrologix processors. Because the PLC-5 processor has built-in network connection, PLC-5 makes the control structure flexible enough to establish economic connection between a wide range of equipment.   The minimum configuration of a PLC-5/1771 control system includes a programmable controller module and some input and output modules and power supply modules installed on a rack. The controller with communication port can be selected as required. PLC-5 can reach 512 input and output points at most. All PLC-5 processors have remote I / O interfaces. Some PLC-5 processors have local extended I / O interfaces. Some PLC-5 processors have local extended I / O interfaces. Some PLC-5 processors have a ControlNet communication int...
