Software project planning
Project planning
Developing application-specific data sets forms the basis
for the function of the VT-HNC100...3X/S. These data sets
are generated on the PC and sent to the VT-HNC100...3X/S
using a serial Ethernet interface. This software parameter-
ization is implemented according to fix steps:
1. Depending on the assignment, the inputs and outputs
and the parameters used are defined.
2. The parameters (selection of transducers and control-
lers) are defined.
3. The data are sent to the VT-HNC100...3X/S.
4. The settings are optimized at the machine.
PC program "IndraWorks"
To implement the project planning tasks, the "IndraWorks"
PC program is available to the user. It serves for parameter-
izing, setting, and diagnosing the VT-HNC100...3X/S.
Scope of service:
Comfortable dialog functions for setting the parameters
online or offl ine
Dialog window for the online setting of the param-
etervalues
Various options for the display of the process variables
Notice:
The PC program "IndraWorks" is not covered by the scope
of delivery.
