CI854/CI854A/CI854B
The CI854 communicates with the 800M controller, and the communication interface CI854/CI854A/CI854B interacts as the PROFIBUS host, and uses RS485 technology to construct the PROFIBUS network. Up to 12 CI854/CI854A/CI854B modules can be connected to a.890M controller and each connection only works as a single PROFIBUS and can be configured with its own transmission rate. Support transmission rate is 9.5; 19.2; 93.75; 187.5; 500; 1500; 3000; 6000 and 12000kbit_ls: supports transfer rates of 31.25 and 45.45 kbit/s. The default value is 1.5 Mbit/s. Higher values require careful consideration of proper cable installation. The PROFIBUS configuration tool in the 800xA system is CBM software. The tool calculates the bus timing parameters and checks the configuration values, which are inserted by the user. For example, compile warnings. This occurs if the slave server does not support the selected transfer rate, in which case the next lower supported transfer rate is automatically selected. Changing the transfer rate may also require changing other bus parameters to ensure successful communication. Automatic calculations will determine the correct Settings. At that time, the adjusted speed effectively debugged the system for all connected devices on the bus.
The CI854, CI854A, and CI854B support hot swap and can be replaced without interrupting CEX communication. After hot removal, hardware information is automatically configured when you insert the CI854.
Compared with CI854A/CI854, CI854B takes a longer startup time, about 25S, and CI854/CI854A takes 5-6 seconds
Versions later than 6.0 support CI854B
In versions later than 6.0, CI854A/CI854 can be replaced by CI854B
