The B&R 2000 controller generation is an automation system that provides new levels of

performance, functionality and operational safety. The B&R 2003, B&R 2005 and B&R 2010

systems cover the entire application range, from simple logic controllers to complex

decentralized automation systems.

The systems have different structures, expandability, modularity and CPU performance. These

systems are very closely related and therefore meet the fundamental requirements for complete

centralized and decentralized compatibility for the programmer.

System Interface

The system interface is the sum of all I/O modules, i.e. the interface between PLC and the

machine/system being controlled. All B&R SYSTEMS 2005 I/O modules are electrically isolated

from external disturbances using suitable EMC measures (standard EN61131-2). I/O modules

are enclosed (plastic housing), so that the technician cannot come into contact with the

electronics at installation.

The length and structure of the I/O bus can be adjusted to the requirements of the

machine/system. That means the connection points for I/O signals do not have to be in the same

location as the PLCs CPU. Using a combination of local and remote I/O bus segments (remote

I/O) allows the optimal structure to be created for the respective application. I/O modules are

installed on the machine/system where they are needed. Cabling to the PLC kernel is reduced

to a two conductor or fiber optic cable.

B&R SYSTEM 2005

The following guidelines apply when configuring every B&R 2005 system:

• System modules are only allowed to be inserted on the main backplane.

• Empty slots must be filled with dummy modules.

• The power supply must always be located in the two furthest left slots (1 and 2) for both

main and expansion backplanes.

• The CPU can be operated on the main backplane directly next to the power supply.

• Counting for module addressing begins at slot 3 which has address 1 on every

backplane.

The module addressing for system modules begins with address 0 (0, 1, 2, etc.) if using

an operating system (CPU) older than version 1.10.

2010 to 2005

B&R 2010 I/O modules can be connected to a 2005 expansion master with an expansion slave

(which has a power supply module inserted into the expansion slot), or to a 2005 expansion

slave (Expansion Slave OUT).

The module address of the 2010 expansion slave is set with a node number switch, from where

the 2010 I/O module addresses begin. Settings are made in steps of ten (00, 10, ..., 90). A

maximum of 20 I/O modules can be installed on one of these bus segments. However, it is

possible to use up to 99 modules with a 2010 expansion master.

2.2.2 Remote I/O Bus

A remote master (B&R SYSTEM 2005, B&R SYSTEM 2010 or B&R SYSTEM 2000 Logic

Scanner) can be connected with up to 31 remote slaves. It is also possible to mix the B&R 2003,

B&R 2005 and B&R 2010 systems.

Each remote slave starts a new I/O bus. The maximum number of slots available depends on

the type of slave

General Information

Backplane modules are installed on the mounting rail. They are used for installing controller

components (CPU, I/O modules, power supply modules, system modules etc.). The I/O bus,

system bus and the supply lines are provided on the backplanes. Backplanes are available with

6, 9, 12 or 15 slots for the B&R 2005.

It is recommended that the smallest possible backplane should be used to ensure that as few

slots as possible remain free. Dummy modules must be installed in all free slots.

The backplane modules 3BP15x.41 are equipped with a lithium battery. The battery is used for

central data buffering on the 2005 PLC (e.g. data and real-time clock for the XP152).

The module address is determined by the slot (slot coding). Module addressing begins with

slot 3, which has address 1. For PLC systems with an operating system older than version 1.10,

module addressing for system modules begins with address 0 (numbers are different for system

modules and I/O modules).
