ABBAC 800M Controller Hardware Product Guide

Satt ControlNet and bridges different bus standards used on AC 800M and 

Satt ControlNet. The CI865 module makes it possible to use older Satt I/O system 

(Rack I/O and Series 200 I/O) with the AC 800M controller platform but it can not 

be used as a general ControlNet interface. CI865 supports online replacement (Hot 

Swap), and does not require any configuration before installation.

CI862 cannot be used in an AC 800M High Integrity controller

CI865 cannot be used in an AC 800M High Integrity controller.

FOUNDATION Fieldbus High Speed Ethernet (FF HSE)

The FF HSE communication interface unit CI860 makes it possible for AC 800M 

controllers to communicate with FF HSE devices via Ethernet. The FOUNDATION 

Fieldbus Linking Device LD 800HSE (see Appendix B, Recommended 

Components) makes it possible for AC 800M controllers to communicate with 

FOUNDATION Fieldbus H1 devices, via CI860 and Ethernet. An example system 

structure with a single CPU is given in Figure 10 on page 42. An example system 

structure with a redundant CPU is given in Figure 11 on page 43. 

CI860 cannot be used in an AC 800M High Integrity controller.

The following schematic figures, with examples of I/O interconnections, do not 

necessarily show the exact amount of connectors or their exact positions.

Drive System

ABB Standard (Std) and Engineered (Eng) Drives can be connected to AC 800M 

through any of the following:

• The optical ModuleBus

• CI801 and PROFIBUS DP

• NPBA-12, RPBA-01, or FPBA-01 PROFIBUS DP Adaptor modules along 

with CI854

• RETA-02 or FENA-01/-11 Ethernet Adapter modules along with CI871 

(PROFINET IO)

• CI858 DriveBus Interface. . 

ModuleBus

In single CPU configuration, ABB Drives can be connected to the processor unit via 

the optical ModuleBus. See Figure 12 on page 47. The number of ABB Drives 

which can be connected to the optical ModuleBus, can be described by the 

following equation: 

(No. of ABB Drives) < 84 - (12 x (No. of TB820s))

that is, each Drive uses one ModuleBus cluster.

PROFIBUS 

In single and redundant CPU configuration, ABB Drives can be connected via 

PROFIBUS DP and CI801. See Figure 12 on page 47. Only Standard Drives can be 

connected to CI801. Fourteen (14) Standard Drives can be connected to each CI801 

if there are no I/O units connected. For the number of Drives that can be connected 

to the same CI801, when both I/O units (TB820) and Standard Drives are 

connected, refer to documentation about FCI for PROFIBUS DP.

For more information about ABB Drives and its types (Std and Eng) refer to 

S800 I/O documentation.

For information about Branching Unit (See Figure 12 on page 47) see ABB Drive 

System documentation.

CI858 cannot be used in an AC 800M High Integrity controller.

ABB drives can also be connected via PROFIBUS DP (CI854/CI854A), with direct 

connection to PROFIBUS DP slave modules NPBA-12, RPBA-01, and FPBA-01.

PROFINET IO and CI871

The RETA-02 Ethernet Adapter module and FENA-01/-11 Ethernet Adapter 

module are optional devices for ABB drives, which enables the connection of the 

drive to a PROFINET IO (PNIO) network. The drive is considered as a PNIO device 

on the PROFINET IO network, and it is compatible with all PNIO controller 

stations that support PROFINET IO and sub-slots.

DriveBus Interface

ABB drives can be connected to the AC 800M via the CI858 unit, see Figure 12 on 

page 47 and Figure 13 on page 48. The drive interface can be used for controlling up 

to 24 drives or inverter units. 

Main communication functions of the drive connection are: 

• dataset communication

• broadcast system time

• supervision and diagnostics functions

The data exchange between the AC 800M and the CI858 consists of eight datasets. 

The drive connection is able to transfer at the maximum 8 datasets / 1 ms.

Connection of multiple drives requires the use of a branching unit, which enables 

the construction of a logical bus with physical star topology, see Figure 13 on page 

48. The branching units can be chained.

The following drives are supported by the drive connection:

• ACS 600 single drive

• ACS 600 multi drive

• ACS 600 thyristor supply units

• ACS 600 IGBT supply units

• ACS 800 product family

• ACS 140-AC S400

• DCS 600 and DCS 400

• ACS 6000 product family / large drives

• ACS 1000 product family

For more information about ABB Drives and its types (Std and Eng) refer to 

S800 I/O documentation, see Released User Manuals and Release Notes on page 

16.

For information about Branching Unit (Figure 13 on page 48) see ABB Drive 

System documentation.

The following schematic figures, with examples of I/O interconnections, do not 

show the placement of the connectors.

Installation

The AC 800M Controller consists of units that are mounted on a horizontal DIN rail 

as shown in Figure 16 on page 51. Each base plate has a locking device that ensures 

contact between the metal back plate and the DIN rail, providing an effective ground 

connection.The locking device can be set to any of the following three positions,
