A programmable automation controller (PAC) is a compact, based on the characteristics and capabilities of a PC-based system to monitor with a controller typical of the programmable logic (PLC). CAP, the most common in the industry for monitoring processes, the acquisition of data, the equipment of remote monitoring, and machine vision from the control of movement. In addition, because they are properly communicating and most of the protocols have a network card, such as TCP / IP, OLE for process control (OPC), and SMTP, CAP are in a position, the transfer of data from machines that control to other machinery and components of a system for monitoring the network, or software for the application and databases. 
     The committees, provincial and machines serve the same goal. Both are mainly used for the automation of the processes of control and data acquisition functions, such as analog and digital processing in the series, PID, control of movement, the vision and the machine. The parameters, which operate under GAP, in order to achieve this goal, however, sometimes contradictory, as a PLC functions.

Unlike PLC, PACS provides open, modular architectures, the reasoning is that, because most industrial applications are able to keep control over the material used for the needs of engineers enable to select the other parts of the architecture of the system control without thought to whether or not, you are with the controller.

CAP and machines are also different than planned. Controllers are often programmed level of logic, a graphical programming language, such as tracks and rungs of ladders, which is to imitate the old schemes for electrical wiring of relays. CCP programs for the most developed generic software tools, which enable its program for about different machines, transformers, HMI terminals or other components in the system to control the architecture.

    Closeup a Programmable Automation Controller (Opto 22) CCP treatment and I / O digitizing is also very different. In contrast to the machines, which do not cease to return, all I / O entries in the system to control the very high rates of speed, CAP nomdebalise only a database and a logical system for the identification and mapping of E / S, if necessary. 

Well known sellers of material for CAP control of General Electric, Bosch Rexroth, Schneider_Electric, National Instruments, Opto 22, Allen Bradley, Advantech, Industrial Automation Group, and ICP DAS. Other supplies such as Siemens A & D, Mitsubishi PLC controller offers, which both the functionality and the CAP on the same system controller.
