1.0 Introduction
The Profibus-DP Interface functions as a slave node to a Profibus-DP master.
The Interface returns weight and status information from an indicator to a
master device and provides limited control of indicator functions to the
programmer. Indicator configuration and calibration cannot be performed
through the
Profibus-DP Interface .
The Profibus-DP master sends commands to the indicator through the
Profibus-DP Interface by writing the commands in the output format. The
Profibus-DP Interface returns the weight and status data in the input format.
These actions are referred to as cyclic I/O. See Section 3.0 for descriptions of
the cyclic I/O commands.
A CD-ROM containing the GSD file used to configure the master device is
supplied with the Profibus-DP Interface.
