2.3 Slave Configuration
2.3.1 General
The following section will detail the basics of configuring the PS69-DPS module.
The PROFIBUS-DP Slave module does not require a configuration tool. There
are two ways to configure the Slave module. These two methods are described
in the following sections.
2.3.2 GSD File
A GSD file is kind of an electronic datasheet for a particular Slave device. The
GSD-File for the PS69-DPS slave named "PSFT097A.gsd" is located on the
DVD supplied with the module. You have to provide this file to the configuration
tool for the network master. Refer to the Master’s user manual of how to import
GSD files.
2.3.3 Configuration by Master
The "Configuration by Master" is the easiest way to configure the Slave. The
projects on the DVD contain examples which show the use of this method.
During the network startup phase, the PROFIBUS Master sends the expected
slave configuration over the network to compare it with the real configuration of
the Slaves connected to the bus. The slave PS69-DPS automatically takes over
the configuration which is sent by the master during its comparison of the
configuration. This method is activated by default, since the parameter "Force
User Config" in the configuration area is set to 0. The only setting required by the
user is setting the Address rotary switches on the front of the module to the
required network address.
Note: This is the easiest way to configure the Slave. But be aware that the master can send a new
configuration to the slave at any time. This can cause inconsistency, if the new configuration does
not match to the controller application. For more safety use the method "Configuration by Controller
Application". With this method the slave module does not start any communication as long as the
slave configuration and the master configuration don't match to each other.
