3. Then the DTMs for the individual VEGALOG module cards must
be added to the project tree. These are in this example: VEGA-
LOG CPU, VEGACOM 558, VEGALOG 571 EP.
4. The two DTM types "VEGALOG 571 EP" and "VEGALOG
571 EV" are VEGALOG module cards for connection of digitally
communicating VEGA sensors. This means appropriate sensor
DTMs can be added to these cards. Select the suitable sensor
DTM from the device catalogue and transfer it into the project
window.
If the sensor is already connected, it is possible to search for it
with PACTware. In this case, the VEGALOG 571 DTM must be in
online mode (right mouse key - "Connect"). Then the automatic
search function can be started via the right mouse key - "Add'l
functions - Instrument search".

5.4 Parameter adjustment (synchronized
operation)
With the parameter adjustment in synchronized operation, the DTM
tries to keep the instance data, this means the data stored in the DTM
are always consistent to the device data. To achieve this, always the
complete data set of the device is read out during connection and
copied to the instance data of the DTM. This mode corresponds to the
standard behaviour of the VEGA DTMs.
After the project is created, the parameter adjustment of the instru-
ment can be started. This is done via double click to the requested
DTM in the project window or via the right mouse key by selecting
"Parameter".
In the following procedure, a difference is made between offline and
online mode.
Offline mode
In offline mode, the project can be prepared, created and stored with-
out connected instruments. Later on, in online mode these data can
be transmitted to the instruments ready for operation.
