AUMA AUMATIC ACExC 01.2 User Manual

3.2. Parameter setting
The parameter setting is partly defined in the Profibus standard, e.g. one bit for
switching bus monitoring on and off (watchdog).
In addition, the Profibus DP interface can receive further user parameters thus
enabling complete configuration of the process representation input. These
parameters can be modified via the programming software of the controls. New
programming software supports the parameter setting via text and a menu selection.
For older versions, the parameters must be entered as hexadecimal numbers.

WD_Base = 0 (time base 10 ms)
WD_Base = 1 (time base 1 ms)
Connection monitoring time of the Profibus DP communication:
T
WD
= (1 or 10 ms, depending on WD_Base) x (WD factor 1) x (WD factor 2)

Settings for Profibus DP-V1 services (option):
DPV1 Enable
Activates the DP-V1 services available as an option; must be set to 1 when using
DP-V1 services.
Settings for Profibus DP-V2 functions (option):
Enable Process Alarm
Enables the process alarm (required for time synchronisation with time stamp), must
be set to 1.
Alarm Mode
Number of supported alarms, must be set to 0 (i.e. one alarm of each type is
supported).
PrmStruct
Structured parameter setting possible, must be set to 1.
PrmCmd
Parameter command activated, must be set to 1 for Profibus DP-V2 redundancy.
In the bytes following byte 10 of the parameter telegram the user parameters for
adaptation of the process representation input to the DCS can among others be
found (AUMA specific parameters).
The GSD file available on the website does not contain any user parameters for
adapting the process representation input to DCS requirements.The actuator will
use the default process representation with this GSD file. For further information
please refer to <Process representation input (default process representation)>.
