Controllogix Series Controllogix series programmable logic controller is introduced in 1998, Rockwell AB series of modular PLC, represents the highest level of the current PLC development, is the world's most competitive control systems one, Controllogix the sequence control, the process control, drive control and motion control, communication, IO technology integration in a platform for a variety of industrial applications to provide strong support for various occasions, the biggest feature is the use the network to their mutual connection between the various controllers in accordance with customer requirements for information exchange.
Controllogix frame structure with all modules are inserted in the frame were the backplane, the backplane supports hot-swappable modules.
ControlLogix simple easy to use environment to achieve excellent performance, called the industry model. ControlLogix controller maximum storage capacity of up to 8 trillion to support the process-intensive applications and rapid motion control applications. According to application requirements, choose different storage controllers. CompactFlash removable storage cards can do the program. Multiple processors, multiple communication modules and I / O can be mixed without restriction. Processor implementation does not require I / O bridging and routing, as the system increases, the available network to control the distribution to another rack.
Advantages: For sequential, process, drive and motion control of modular, high-performance control platform: Each ControlLogix processor can execute multiple control tasks, reducing the number of required controllers, so quicker troubleshooting. Can trigger multiple periodic tasks are to achieve higher levels of performance.
Unrestricted mixing multiple processors, networks and I / O: ControlLogix platform, high performance, some from as fast NetLinx network operations ControlLogix backplane. ControlLogix processors, I / O and communication modules as a network of intelligent nodes.
Common programming environment and Logix control engine: either use the platform and network, by using the common control model, can reduce system costs and simplify integration. Configuration and programming is the same, so regardless of the beginning of a long-term program development or system maintenance, can spend less effort.
Connected to the NetLinx open network structure: in the context of the whole plant, from floor to management, from the Internet to e-manufacturing applications, all of a seamless communication of information.
I / O modules wide range of: analog, digital and specialty I / O modules to meet the application requirements.
Product Design ControlLogix processor to provide a modular user memory (750K to 8M bytes) to solve a large number of I / O issues (4000 points 128,000 points analog and digital). Can control the local and remote I / O. Processor can EtherNet / IP, ControlNet, DeviceNet, and Universal Remote I / O control I / O.
When ControlLogixI / O chassis has a number of processor modules, even in the ControlNet network has a number of processor modules, all of the processors can read from all input modules input. Any processor can control the output of any particular module. Specified by the system configuration for each output module consists of processors which control.
ControlLogix platform is a modular rack installation. ControlLogixI / O is back installed. Power directly on the ControlLogixI / O rack left. ControlLogixI / O chassis slot of a 4,7,10,13, or 17 points. Module slot number and install completely irrelevant; any module can be installed in ControlLogixI / O slot of any frame. ControlLogix I / O modules, the maximum number of channels is 32 channels. Each module removable terminal block imposed by mechanical keying to prevent incorrect voltage to the module. Connection can be replaced without disconnecting I / O modules.
Communications Addition to the built-in RS-232 (DF1/DH-485 Protocol) port, the network communications interface is modular. Including EtherNet / IP, ControlNet, DeviceNet, DH +, and Universal RemoteI / O. Can also be connected to Profibus DP and Modbus and other networks.
