This setting is accepted only if the ESK4-PA transmitter is calibrated for level measurement.
Functionality is reduced to the requirements which are mandatory in the PA Profile; i.e. 1 AI-FB
is available for cyclic data transfer only. Device specific diagnosis information is not available via
cyclic PROFIBUS services. Nevertheless this behaviour will improve interchangeability between
devices of different vendors because only functions are available which are provided by all
PROFIBUS PA level devices. Exchange is possible without modifying the configuration of the
control system.
Cyclic layout:
GSD file PA139700.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.

Compatibility mode (ESK3-PA: F201hex)
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. 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 KROHF201.GSD is required in this mode. If the ESK4-PA transmitter is connected to a
Fuchs PROFIBUS DP/PA segment coupler SK2 or SK3 the GSD file YP01F201.GSD shall
be used. Take care that
“
Condensed Status
”
is not supported in this mode for compatibility
reasons.
