Controllogix introduction

Controllogix introduce newmaker welcome to e hall exhibition hall 3 PLC controller PLC programmable controller, PLC programming cable. 。 。 Since the rockwell automation since entering China in 1987, its products are widely used in manufacturing processing industry. Rockwell company in the field of automatic control has many famous brand, AB ( 艾伦- 布拉德利) Is one of the brand, including more than five hundred thousand kinds of products, and provides industrial control and system solutions. Is rockwell Controllogix company launched in 1998 AB series modular PLC, represents the highest form of development, the current PLC is one of the world's most competitive control system, the Controllogix sequence control, process control, drive control and motion control, communication, IO technology integration on a platform, can provide strong support for a variety of industrial applications, suitable for various occasions, the biggest characteristic is can use the Internet to connect each other, between each control station can according to customer requirements for the exchange of information. Controllogix adopts frame type structure, all modules are inserted on the back of the frame, the back support hot-swappable modules. The figure below shows the typical network architecture: as you can see from the table, the Controllogix ability of the network can make the controller IO terminals don't have to be on a local, but can be placed in technology field, CPU framework can bus ( controlnet) To accomplish the transmission of information, a bit like a traditional DCS structure, greatly expand the application range of the Controllogix this way. On the basis of the above can be convenient to build into AB typical three layer structure of the network, the network can put all of the organic integration of system equipment as a whole, become a part of the current ERP system. In view of the high reliability requirement of industrial field, Controllogix could provide perfect controller redundancy function, with the method of hot standby build controller, two frameworks using exactly the same configuration, using synchronization between cable connection, the controller not only can be used in a hot standby, telecommunications network also can be used in a similar way to hot standby, as follow: in addition to the above part can be hot standby, the power of the controller can also be hot standby, so greatly improve the reliability of the operation of the controller. In a communication network, Ethernet/IP, controlnet is a common communication protocol, in addition, Controllogix also supports devicenet, DH +, RS232, DH485, etc. Using Ethernet/IP can easily access to the local area network (LAN) as the controller, and LAN computers work together. Controlnet is a high-speed bus protocol, can support 5 m/S rate of communication, mainly used in the controller between the controller and the exchange of information between the IO framework, have the ability to send/receive more more, can communication medium for coaxial cable or optical cable, distance can reach as far as 30 kilometers, in the case of using a third-party communication adapter, can achieve seamless connection, and other bus protocols such as modbus. On Rslogix Controllogix programming software is Rslogix5000, can use ladder diagram programming in the form of graphical interface makes heavy programming development has become a kind of fun, as long as the program after the completion of the above can be downloaded to the controller module, greatly shorten the development cycle. Rsview32 provides monitoring control function based on component, its powerful features not only can be used for the Controllogix man-machine interface configuration, but also can be used for other PLC monitoring, functions are comparable to those obtained with intouch. Rsnetworx is a network scheduling software, if you use the controlnet, must be used rsnetwors to set the related parameters of the network, network can't work normally. The above three software are based on RSLINX, RSLINX is for all the Controllogix module driver, also support all AB bus protocol. Relationship is as follows: the software have good interface, whether expert or novice, can use the software for industry field service quickly. Through the combination of software and hardware, the Controllogix is stable and reliable to complete industrial control requirements, using a variety of craft.
is emerging as one of the most popular plc manufacturers, moving beyond its programmable control systems benefits, with conclusive scientific evidence suggesting the positive role play in plc controller price.
