M&I – AC 900F Controller 43
 
CI CAN Bus module
An AC 900F controller with CI 910F CAN Bus module allows for connecting rack-
based I/O modules. 
CI 910F CAN Bus interface 
The CI 910F CAN Bus interface comprises three CAN Bus lines, CAN 1 to CAN 3. 
The lines are electrically isolated from the system and designed for redundant 
operation with a second AC 900F controller. 
The internal coupler bus connects the CI 910 F to the CPU module. This is valid for 
both data transmission and power supply. A dual port RAM is used for data 
exchange.
