Example 2:
a0004791
Fig. 34: In this configuration example, modules that are not needed are replaced by the module EMPTY_MODULE.
The Promass 80 GSD file is used.
With this configuration, the Analog Input function block 1 (slot 1), the totalizer value TOTAL
(slot 5) and the cyclic control of device functions CONTROL_BLOCK (slot 8) are activated. The
mass flow (factory setting) is read out cyclically by the measuring device by means of the Analog
Input function block 1. The totalizer is configured "without configuration". In other words, in this
example it only returns the totalizer value for the mass flow (factory setting) by means of the TOTAL
module and cannot be controlled by the PROFIBUS master (Class 1).
