DME 3000-2 _ _P
Software 1.1

4.2.9 Profibus Profile

Two profiles are available in the DME 3000-xxxP. Dependent on the selected profile, only one GSD
file is required. Integration and parameterization of the DME in a bus system is very simple with the
projecting tools based on the GSD files.
The GSD file corresponds to a standardized GSD file for encoders and consequently also contains
parameters, which do not affect the DME.
The specific parameters for the DME are explained below:
Expanded diagnosis
Scaling function
Inverting Out1/Out2
Average
Display offset (31-16)
Display offset (0-15)
Switching threshold output 1(31-16)
Switching threshold output 1(0-15)
Switching threshold output 2(31-16)
Switching threshold output 2(0-15)
Hysteresis output 1
Hysteresis output 2
Diagnosis interval x 100 ms

4.2.9.1 Encoder-Profile

This profile is compatible with the standard encoder profile.
A reservation of 32 BIT input data is made for the measurement values, 24 BIT of which are required
for the measurement range of the DME.
A reservation of 32 BIT output data is also made, with which a reference value can be transmitted to
the DME when BIT31 is set.
Diagnosis data of the DME can only be read via the cyclical transmission of diagnosis data. The
"Expanded diagnosis" parameter must be activated for this, and a cycle time must be defined for the
"Diagnosis interval". Then the diagnosis data can be read in the diagnosis data range of the SPS
(programming of the OB82 is required at S7).
Refer to the appendix for the precise distribution of the diagnosis data.

4.2.9.2 SICK-Profile

In this profile, the highest value 8 BIT of the 32 BIT input data not required for the measurement value
are used for transmitting warning, status and error information.

equipment defect).

Activated means a resolution of 1/8 mm
