[PROFIBUS Master Commands]
The [PROFIBUS MASTER COMMANDS] section of the CFG file sets the
PROFIBUS master port command list. This list polls slave devices attached to a
master port. The module supports three commands. This permits the module to
interface with a wide variety of PROFIBUS slave devices.
The command list is formatted differently than the other sections of the
configuration file. Commands are present in a block between the labels
START
and
END
. These labels inform the program where the list resides. The module's
program will parse all commands after the
START
label until it reaches the
END
label or until the command count entered for the port is reached.
The format of each command in the list is the same with the content dependent
on the operation to perform. The following table describes the format and list of
PROFIBUS Master functions supported:
