Software project planning

Project planning

The creation of a parameter file forms the basis for the func-
tion of the HACD. The parameter file contains the block struc-
ture of the HACD in which the links of the variables will be 
created. The parameter files are created in BODAC. The 
parameter file can be created offline and transferred to the 
HACD by means of a PC.
This software project planning is implemented according to 
the following steps:
1. Selection of the HACD.
2. Application is defined by means of the block structure.
3. Setting of the parameter values (sensors, controllers...).
4. The data is sent to the HACD.
5. Storage of the data in the flash.
6. The setting and the machine sequence are optimized at 

the machine.

PC program BODAC

For the implementation of the project planning tasks, the 
BODAC PC program is available to the user. It serves the 
programming, setting, and diagnosis of the HACD.

Scope of services:

–  Comfortable dialog functions for setting the machine data 

online or offline

–  Dialog window for setting the parameter values online
–  Comprehensive options for displaying process variables, 

digital inputs, outputs, and flags

–  Recording and graphical presentation of up to eight pro-

cess variables with great selection of trigger options

PC-System requirements:

–  Windows XP, Windows Vista, Windows 7
–  Random access memory (256 MB recommended)
–  250 MB free hard disk capacity

Note:

The BODAC PC program is 

not

 included in the scope of de-

livery. It can be downloaded in the Internet free of charge!
