5.3.1
Configuring with Address Space Optimization
Requirement
You can operate the DP/ASi link with any DP master that conforms with the
DP standard and supports a parameterization message containing 140 bytes
(full assignment of parameters).
Basics
We will confine ourselves here to showing you how to address the DP/ASi
link on the PROFIBUS-DP side.
Configuring
Configure the DP/ASi link in the following order:
Step
Action
1
Define the installation of the ASi.
2
Optimize the address assignment of the
input and output data of the DP/ASi link
(refer to appendix C.3).
3
Create the parameterization data from the
address assignment received.
4
Create the parameterization message (re-
fer to appendix C.1).
5
Create the configuration message (refer to
appendix D.2).
Commissioning
You commission the DP/ASi link as described in section 4.3. The DP/ASi
link performs as described in chapter 7.
DP standard slave
The DP/ASi link behaves like a DP standard slave.

Configuring the DP/ASi Link
Meaning
From the installation, you learn the total num-
ber of inputs and outputs that you will assign.
In this way you make optimum use of the limi-
ted address area.
You require the parameterization data of the
ASi slaves for the parameterization message.
The DP/ASi link requires the data contained in
the parameterization message upon power up.
In the configuration message, define the num-
ber of bytes for the input and output data.
