Option Description
SIMULATION SIMULATION—Simulates two floating point values and
error/status to act like a real instrument. Select the following
options and use the arrows to enter the values or use the
default setting:
• SIMULATION:Turns the simulation on or off.
YES: Starts a simulation
NO: Stops a simulation (default setting)
• PERIOD:Sets the time the first floating point value needs
to run through the whole range between MINIMUM and
MAXIMUM—2 min (default setting)
• MAXIMUM: Sets the upper limit for the first floating point
value.—20.0 (default setting)
• MINIMUM: Sets the lower limit for the first floating point
value—10.0 (default setting)
• ERROR: The value entered in this menu will be set in the
first simulated tag—16 (default setting)
• STATUS: The value entered in this menu will be set in
the second simulated tag—5 (default setting)
• TOGGLE: Changes the direction of the simulated ramp.
• TEST/MAINT:
ENABLED: Sets the TEST/MAINT bit (0x0004) of every
status register of every configured slave in the cyclic
Profibus telegram to indicate the "Service" mode.
DISABLED: Normal operation mode (default setting)
VERSION Software version of the Profibus network card.
Option Description
LOCATION Edits the location name.
STATUS STATUS— Indicates the Profibus network card status
• PLEASE WAIT: is shown until the network card has
found all configured slaves or is displayed when the card
is new configured and is searching for sensor
connections
• PLC CONFIGURE ERR: is shown when the network
card has received a wrong configuration of a PLC
(programmable logic controller). Check the GSD file.
• READY: is shown when the network card is ready to
send data to the Profibus. Check the address and/or the
wiring.
• ONLINE: is shown when the network card is in contact
with PLC and cyclic Data is sent

Device order

The device order in the Profibus telegram is fixed. The first and the
second installed devices are always on position one and two and the
analyzer is on position three.
When no device is installed, the analyzer will stay in position three. The
position for the uninstalled devices will be filled with 0xFF.
If two devices are connected (maximum allowable) and scanned at the
same time, the installation order will be based on the location where the
device is connected. The installation order is:
• Digital device 1
• Digital device 2
• Analyzer
Standard data structure (Auto configuration)
When the auto configuration (default) is selected, the Profibus network
card supplies a pre-defined data telegram for each connected device.
The telegram contains important data about the device.
The data block structure of the Profibus messages is standardized for all
types of probes. For the data block structure, refer to
and Table 3 for the analyzer.
