3.3 Using the TEDS-Editor
Calling up the TEDS Editor presupposes that the transducer to be edited is
recognized as the TEDS transducer by the higher level software. Call up the
Editor by clicking on ”Edit TEDS” in the context menu, which can be opened
by right clicking on the transducer.
The TEDS Editor offers two operating modes: The HBM view and the
Template view. The TEDS Editor supports the user rights hierarchy, consisting
of the permissions IDENT (manufacturer), CAL (calibrator), USR (user) and a
level with exclusively read rights (see chapters 2 and 4 regarding the rights of
the various levels).
USR is set by default for the operator. When the higher level software is
implemented via the access to the Assistant which has user rights
administration (e.g. MGCplus Assistant), the user rights can be modified. This
is in particular necessary when the operator has to implement the module
programming themselves after installing the TEDS module.
NOTE
If the user rights in levels CAL or IDENT are used, there is a
danger of unintentional overwriting of the central transducer data.
3.3.1 Editing TEDS in the HBM-view
The HBM view is orientated around the definitions and transducer parameters
that are normally used with HBM measurement technology. For example, the
input of a transducer characteristic curve can be implemented in two ways:
•
Value pair based on nominal value (e.g. the nominal force for a force
transducer) and sensitivity (output signal at nominal value, minus the
output signal in relaxed state).
•
Input of two points that are each defined by a physical value and the
respective output signal.
The setting options essential for working with HBM transducers are clearly
laid out in the form of ”tabs” that simply have to be filled in. Editing options are
restricted when working with user rights in the hierarchies USR (operator) or
CAL (calibrator). A separate field displays the entries that are stored in the
basic memory (Basic TEDS). Changing entries in the basic memory (apart
from the serial number) requires that a completely new TEDS content must be
generated. The following tabs are available:
