Compatibility mode (Profile: 9740hex)
This setting supports a compatibility mode concerning the cyclic data transfer (cyclic measurement values
and diagnosis) if the ESK4-PA transmitter shall be used for replacement of an ESK3-PA transmitter while
the ESK3-PA was operating in Profile specific mode. The ESK4-PA transmitter emulates the cyclic
behaviour of the ESK3-PA transmitter. Status and diagnosis are restricted to the capabilities of this
transmitter. Therefore it is usually not necessary to modify the configuration of the control system if it is
configured for operation with an ESK3-PA transmitter.
Cyclic layout:
GSD file PA139740.GSD is required in this mode. This file is provided by PROFIBUS International
(see www.profibus.com). This file might be used for all types of PROFIBUS DP/PA segment
couplers. Take care that
“
Condensed Status
”
is not supported by this file.
INFORMATION!
The IDENT_NUMBER_SELECTOR changes the behaviour of the ESK4-PA transmitter from the
communication point of view. In addition it might be necessary to set additional parameters to
suitable values in order to adapt the measuring behaviour to ESK3-PA.
INFORMATION!
Although the cyclic behaviour of the ESK3-PA is emulated by the ESK4-PA transmitter the
acyclic behaviour is not changed. Therefore a DD/DTM for ESK4-PA has to be used to set
parameters/read measuring values and diagnosis even if the compatibility mode is active.
Extended diagnosis information is still available on this way.

Totalizing is stopped if the ESK4-PA transmitter is calibrated for level measurement.
INFORMATION!
If another GSD file is used in the PROFIBUS master system the cyclic data transfer cannot be
established in this setting.

This operation mode cannot be entered via the Automatic adaptation mode (see above).
