Commissioning
EL6201
109
Version: 2.2
Management phase
During the management phase, an AS-i command is sent if an operating address is to be set via automatic
address programming, or if an AS-i command was requested via the AS-i command interface (index
0x2000
[
}
134]
). Otherwise the AS-i master enters the inclusion phase without issuing an AS-i command.
Inclusion phase
During the inclusion phase, only one command is sent. The system will attempt to find and activate new AS-i
slaves, and the respective status is updated accordingly. The steps are the same as during the recognition
or activation phase, except that they are now distributed over up to seven cycles.

Address assignment of the AS-i slaves
Address assignment can be done via the AS-i master or via an addressing device. AS-i slaves are usually
supplied with address 0. Slaves that were added later are searched under this address, and an address is
then assigned. Address 0 is not permitted during the data exchange phase.
The extended addressing is supported from AS-i specification 2.1, so that corresponding slaves can also be
given the addresses 1B to 31B. 0B is not permitted.
Normal address assignment
New AS-i slaves usually have address 0. An addressing call command can be initiated via the parameter
0x2000 [
}
134]
(AS-i command interface). However, the addressing call command only works if precisely one
AS-i slave with address 0 is connected to the bus. A further addressing possibility is shown in the

Automatic address assignment
Automatic address assignment
Automatic address assignment must be enabled in index
0xF100:03 [
}
141]
.
Configuration mode
In configuration mode, the next free address is automatically assigned if a slave with address 0 is found.
Protected Mode
In protected mode, an AS-i slave with address 0 is automatically programmed with its new address, if
precisely one currently projected AS-i slave is missing, and if no other not currently projected AS-i slave is
present at the bus. This enables a (no longer functioning) AS-i slave to be exchanged during operation.

Quickstart
No special measures are required for the initial commissioning of the EL6201.
Knowledge of the introductory Technology section is required.
The following examples initially illustrate
manual
addressing and integration of a digital AS-i slave in the
TwinCAT system.
For
automatic
addressing the EL6201 is commissioned with two digital and one analog AS-i slave, for
example.
The EL6201 is commissioned with the following configuration:
• Operating system Windows 7 Professional SP1
• TwinCAT 2.11 R3 Build 2256,
AS-i System Manager Extension
installed
• Terminal network EK1100, EL1202, EL6201 and EL9010
