With the development of Intelligent Manufacturing in China 2025, Rockwell PLC as the core of control system plays a crucial role in modern automation engineering projects. China also ushered in the high speed growth period of Rockwell PLC market, how to standardize the choice of Rockwell PLC?
The 1756 series of PLC in the traditional I/O system, the controller polling module is input to obtain its state. After the connection is established, the host controller no longer polls the ControlLogix high speed analog input. On the contrary, the module regularly multicast its input data. The multicast frequency depends on the configuration of the module, such as the RTS and the RPI rates.
1794FLEX I/O is a distributed I/O system that can connect a variety of networks, including EtherNet/IP, ControlNet, and DeviceNet. The I/O has high flexibility, low price and modular design, which is very suitable for distributed applications.
The modular design of the 1794FLEX I/O system not only gives you the flexibility to choose the network, but also makes the extension more relaxed. The end connection of the cable is almost all carried out on the terminal seat. The terminal parts of the terminal seat include a screw clip, a spring clip and a cage clamp, which can directly connect 2 wire, 3 wire or 4 wire equipment. In addition to providing D type knife head, isolating switch and fuse terminal seat and other options.
The 1734-EP24DC POINT I/O module is the available POINTBus backplane current and 3A field power supply of the embedded I/O and local expansion module, whose total current consumption is no more than 1A. According to the application configuration, additional POINTBus backboard current or field power current can be used.
