C1854/CI854ACI854B

Ci854 is communicatively connected with the 80om controller. The communication interfaces ci854 / ci854a / ci854b are used as PROFIBUS hosts to interact with each other, and RS485 technology is used to build the Profibus network. Up to 12 ci854 / ci854a / ci854b modules can be connected to an 800m controller, and each interface operates as a single PROFIBUS, and its own transmission rate can be configured. The support transmission rate was 9.6; 19.2; 93.75; 187.5; 500; 1500; 3000; six thousand

And 12000kbit! s。 no

The supported transmission rates are 31.25 and 45.45 kbits. The default is 1.5 Mbit / s. Higher values require careful consideration of proper cable installation. The Profibus configuration tool in 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. If the selected transmission rate is not supported by the slave server, then

In this case, the next lower supported transmission rate will be automatically selected Changing the transmission rate may also require changing other bus parameters to ensure successful communication Automatic calculation will determine the correct settings. - At that time, the adjusted speed is effective for debugging the system for all connected devices on the bus.

Ci854 / ci854a / ci854b support hot swapping, and can be replaced at will without interrupting the CEX communication. After hot swapping, the hardware information will be automatically configured when newly inserted,

Compared with ci854a / ci854, ci854b requires a longer start-up time, which is about

About 25s, ci854 / ci854a needs

In 5-6 seconds

Ci854b version is supported after version 6.0

Ci854a / ci854 can be replaced by ci854b in versions after 6.0
