ABB GOP2 High Speed Data Communication

ABB GOP2 High Speed Data Communication

The GOP2 network, or controller network, is a network used in the FA field for high-capacity data exchange between PLCs and between computers and PLCs. The computer can monitor and control the PLCs on the network through the Controller Link support software. There are two types of CLK support cards for personal computers: one is the cable-type 3G8F5-CLK21-E, and the other is the fiber-optic cable-type 3G8F5-CLK11-E. The Controller Link network supports data linking, data sharing, and information communication. The Controller Link network supports data linking, data sharing and information communication, and the data link area can be freely set to form a data link system.

The GOP2 communication medium can be twisted pair or fiber optic cable. The cable-type Controller Link network is connected by twisted-pair cables, which are easier to handle and maintain than coaxial cables or fiber-optic cables, reducing the cost of connecting the network. The distance of communication can be up to 1km. fiber-optic type Controller Link network uses fiber-optic connection, which can get more high-capacity data link and longer distance communication, and its distance of communication can be up to 20km.

The baud rate of GOP2 controller network is up to 2Mbps, much higher than the 128Kbps of PC Link network. large-capacity data link Each PLC can send up to 1K words, and the total number of bytes sent and received can be up to 8K. the data link can be set up automatically or manually according to the actual needs, very flexible. Information communication is realized by executing communication instructions SEND, RECV and CMND in the user program. Network communication can be easily realized by executing the communication commands.
