Default identifier: Symbolic name of the channel
The name of the channel is defined in the configuration file. Only if it is allowed by the
definition of the father module, the name of the channel can be edited in the
configuration tree.
Comment: Additional information on the channel
In the edit field a comment can be inserted or modified.
Address: This edit field only will be available if it was activated by an entry in the
configuration file. Insert the desired address for the channel.
Channel parameters
Corresponding to the Module parameters dialog the Channel parameters dialog is
used to display and modify the parameters of a channel: Index, Name, Value, Default,
Min., Max. This dialog also can be replaced by a customer specific dialog 'Custom
Parameters'.
Bitchannels
Bitchannels are automatically inserted, when a channel is defined with an entry

The Basis parameters dialog of bitchannels just contains the field Comment.
8.2.4 Configuration of Profibus Modules
»PLC Designer« supports a hardware configuration corresponding to the profibus DP
standard. The use of a PLC target from version 7 is required.
A PROFIBUS DP system consists of one or several masters and their slaves. First the
modules must be configured so that a data exchange over the bus is possible. At the
initialization of the bus system each master parameterizes the slaves which are
assigned to it by the configuration. In a running bus system the master sends and/or
requests data to/from the slaves.
The configuration of the master and slave modules in »PLC Designer« is based on the
GSD-files attached to them by the hardware manufacturer. For this purpose all GSD-
files which are stored in the configuration files directory will be considered. The
modules described by a GSD-file can be inserted in the configuration tree and their
parameters can be edited there.
Below a master there can be inserted one or several slaves.
