The control station equipment is composed of Allen Bradley controllogix5555 controller, I / O module, communication interface module, dhrio module, DeviceNet module, flex I / O adapter and I / O module. Its main task is to collect and process process data; According to the control program to implement real-time process control; Carry out equipment monitoring and system testing and diagnosis.

The PLC control system of PVC compound, filling and reinforcing agent production line consists of a main line ControlNet high-speed network, a set of redundant hot standby process control station, DeviceNet, remote I / O, flex I / O, two operator workstations, an engineer workstation and various software packages. In order to ensure the reliability of system communication, the ControlNet network in the system configuration adopts double network redundancy.

The system consists of data acquisition, basic control and monitoring management system. Its automation network configuration is shown in the figure, process control station

Controllogix5555 processor is the latest generation of Allen Bradley controller. Different from the traditional controller, ControlLogix has the ability of communication in its kernel (backplane) design, which eliminates the bottleneck of system communication.

Logix5555 processor is a 32-bit bus controller. Its control ability can reach 168000 digital quantities and 4000 analog quantities. It can not only control the input and output modules of local frame, but also control the input and output modules of other remote frames on the network.

Different from the traditional PLC, ControlLogix backplane design has communication ability, which greatly improves the communication performance of the system. The multitask control mode makes the loop regulation more real-time and I / O communication faster.

The control system of PVC compound, filling and reinforcing agent production line adopts two controllogix5555 controllers to form redundant hot standby. When the system is powered on, the two controllers compete to become the main controller. When the main controller fails, the redundant module 1756-srm immediately switches to the standby controller automatically.

2) Fieldbus (DeviceNet)

DeviceNet is a kind of Fieldbus developed by Rockwell AB based on CANbus technology, which is used to realize low-cost and high-performance device layer network interconnection. It is an international standard bus as well as a national standard bus.

DeviceNet is used for the communication network between field equipment and control system. The transmission rate is 125-500kbps, the maximum transmission distance is 500m, and the maximum number of nodes is 63. It allows online configuration and live plugging.

DeviceNet supports master-slave, multi master and peer-to-peer communication. Users' applications and data can be effectively controlled by DeviceNet.

DeviceNet uses rsnetworx software for network management and configuration. You can select several specially defined configurations, print data tables, parameter object programs and spreadsheets.

DeviceNet has simple network structure, strong real-time performance, advanced communication mode, supports a variety of communication protocols, can dynamically or statically assign identifiers according to application requirements, increase or decrease nodes online, and plug and play. It is an ideal device layer fieldbus network.

The control system of PVC compound, filling and reinforcing agent production line adopts Schneider ATS48 series soft starter to realize the soft start and soft stop of important monomer equipment such as high-speed mixing heater, cone mixer, roots blower, grinder and dryer, and ABB ACS400 series frequency converter to realize the accurate quantitative control.

Soft starter and inverter communicate with controllogix5555 controller through DeviceNet Fieldbus. Through DeviceNet protocol, each DeviceNet adapter occupies three control words and status words to realize start-up and stop control and speed setting,

Condition monitoring, frequency and current display and interlock control.
