Parameterization Behavior - Siemens SITRANS TW 7NG3242 Betriebsanleitung

rising and falling tendency. The step width can also be calculated with the settable
number of steps.
The time between two consecutive simulation values is determined by the step
duration.
In the simulation for the primary measured value, the analog output follows the
simulated values.

4.2.19 Parameterization behavior

4.2.19.1 "Offline parameterization"
It is possible to parameterize the device with SIMATIC PDM or the HART
communicator without a device being connected to the operating software. With this
type of parameterization ("offline parameterization") device-independent data can be
created, saved and stored in individual devices. The following instructions must be
observed for the "offline parameterization".
• When sending the data records to the connected device, make sure that these
meet all hardware requirements. (e.g. Is there a limit value alarm in the device?
Is the device suitable for measuring currents?). Failure to observe this could lead
to parameterization errors.
• This device allows "offline configuration" of all device parameters except the
linearization type parameter. The linearization type can only be parametrized
"online". However, for the linearization type the device firmware sets a standard
value after receiving the "offline" parameterization datarecord. This restriction
does not apply when operating the device with SIMATIC PDM. However, the
PDM-Device Description Rev. 2 is required. (SIMATIC PDM 5.2 already contains
the PDM-DD Rev. 2). An update for SIMATIC PDM 6.0 is available under

4.2.19.2 "Cloning"
If several transmitters with the same parameterization data are to be installed,
"device cloning" is a simple way of cutting down on setting work.
The following procedure is recommended for "device cloning".
1. Parameterization of the reference transmitter according to the desired measuring
task.
2. Reading out and possibly editing and saving the data record by the reference
transmitter
3. Sending the reference data record to other transmitters
