NOTE: When working with PLC systems that are proprietary in nature you must be sure that any generic hardware or software you use is compatible with your particular PLC.ДЎ3 I/O Configurations Fixed I/O Is typical of small PLCsД¬omes in one package, with no separate removable units. A closed architecture or proprietary system, is one whose design makes it more difficult to connect devices and programs made by other manufacturers. The control program can be watched in real-time as it executes to find and fix problemsДЎ1 PLC Architecture Refers to the PLC hardware or software.ДЎ2 PLC Architecture An open architecture design allows the system to beД¬onnected easily to devices and programs made by other manufacturers. Machines that process thousands of items per second and objects that spend only a fraction of a second in front of a sensor require the PLCвЂ™s quick response capability.Д®asier To Troubleshoot: PLCs have resident diagnostic and override functions that allows users to easily trace and correct software and hardware problems. They can be networked to perform such functions as: supervisory control, data gathering, monitoring devices and process parameters, and downloading and uploading of programs.ДЇaster Response Time: PLCs operate in real-time which means that an event taking place in the field will result in an operation or output taking place.

Generally, if an application requires more than about 6 control relays, it will usually be less expensive to install a PLC.Д¬ommunications Capability: A PLC can communicate with other controllers or computer equipment. The cost savings using PLCs have been so significant that relay control is becoming obsolete, except for power applications. Lower Costs: Originally PLCs were designed to replace relay control logic. End-users can modify the program in the field.

It is easier to create and change a program in a PLC than to wire and rewire a circuit. More Flexibility: Original equipment manufacturers (OEMs) can provide system updates for a process by simply sending out a new program. Since all the logic is contained in the PLCвЂ™s memory, there is no chance of making a logic wiring error. Increased Reliability: Once a program has been written and tested it can be downloaded to other PLCs. The program takes the place of much of the external wiring that would be required for control of a process. It uses a programmable memory to store instructions and execute specific functions that include On/Off control, timing, counting, sequencing, arithmetic, and data handling.Д®liminates much of the hard wiring that was associated with conventional relay control circuits.
