ABB CI858K01 3BSE018135R1 DriveBus Interface
Description:
CI858K01 is ABB control system 800xA communication module. 
Package including:
- CI858, Communication Interface
- TP858, Baseplate
The CI858 unit consists of a communication expansion base plate board CEB, a communication expansion module board CEM, and mechanics. All electronic devices and all functions are located on the CEM board.

The DriveBus protocol is used to communicate with ABB Drives and ABB Special I/O units. DriveBus is connected to the controller via a CI858 communication interface unit. The DriveBus interface is used for communication between ABB Drives and AC 800M controller.

The DriveBus communication is especially designed for sectional drive applications for ABB rolling mill drive systems, and ABB paper machine control systems. The CI858 is powered by the processor unit, via the CEX-Bus, and therefore does not require any additional external power source.

Features:
The maximum number of CI858 units connected to the AC 800M is two. The functional structure of the CI858 includes • CEX bus interface: Communication between the CI858 and the AC 800M is implemented through the CEX bus. The CEX bus operates with a clock frequency of 64 MHz. The maximum transfer data is ~1.25 MBytes/s. 
• DDCS interfaces for
– DriveBus
– I/O Bus
– PC Tool 

• +24 V power supply from the CEX bus. 
• DC/DC conversion from +24 V to +5 V, + 3.3V and +2.5 V. 
• Motorola Digital Signal processor DSP56303 with 72 MHz CPU frequency. 
• Xilinx XC2S50 FPGA for the CEX bus interface. 94 user I/O pins available on CI858. 
• 32 kB boot PROM, AT27LV256, for boot code. 
• 1 MB flash PROM, Am29DL800B, for program code. 
• 768 kB SRAM program and data memory. 

AC 800M and CI858 communicate with each other via dual-port RAM, DPRAM. The DPRAM has the following functionalities: 
• Dual-port memory, 32 * 16 kB. 
• One interrupt in each direction. 
• Eight semaphores which simplifies the utilization of shared resources. 
• ONCE port which can be used for reprogramming the module.
