Note concerning this Configuration Manual
The rotary pushbutton on the positioner allows the Type 3730-4 Positioner to be operated
and configured on site. In addition, the settings can be performed over the PROFIBUS-PA
network or over the SAMSON SSP interface. The Mounting and Operating Instructions
EB 8384-4 EN describe the mounting, start up and on-site operation.
This Manual (KH 8384-4 EN) describes the basic principles as well as parameters for opera-
tion and configuration over the PROFIBUS-PA network.
Note: Information on the EXPERTplus diagnostics is included in the Operating Instructions
EB 8389 EN.

K 1.01 Internal modifications
K 1.10 The FEATURE_SELECT parameter allows you to set whether an active diagnostic func-
tion is to be reported by a GOOD_FUNCTION_CHECK or a BAD_FUNCTION_
CHECK (see page 54).
K 1.11 – More trigger conditions in the data logger (see page 53)
– More additional functions (FEATURE_SELECT) (see page 54)
– The limits of the discrete valve position (POS_D_LIMIT_LOW, POS_D_LIMIT_UP) can
now be defined as required (see page 7).
K 1.12 Resetting the identification parameters resets all the parameters saved in the controller.
The parameters saved in the controller are, however, not reset when just the start-up
parameters are reset (see page 42).
K 1.13 Internal modifications
K 1.15 Feature of ID number adaptation acc. to PROFIBUS PA Profile 3.02 added. It allows a
Type 3785 Positioner (Profile 2.0 and Profile 3.0) to be directly replaced with a
Type 3730-4 Positioner in the compatibility mode (see page 8).
K 1.16 The function to suppress extended diagnostic messages allows messages for the
PROFIBUS diagnosis protocol to be suppressed. The messages are still included in the
condensed state according to their classification. The parameter to suppress the diag-
nostic messages exists in the following integrations:
DD: 2.2.007
TROVIS-VIEW: >3.60.005 (device module)
DTM: 1.3.0.1
K 1.17 The versions K 1.12 to K 1.16 do not save a reference variable received in acyclic
data exchange as the valid value for the fail-safe action 'Last valid setpoint is used'. In
the affected modules for data exchange, the polling for a valid reference variable has
been changed to GOOD_NON_SPECIFIC.
K 2.00 Partial stroke test (PST) and full stroke test (FST) added

1 PROFIBUS-PA communication
The PROFIBUS-PA is a fieldbus version for process automation based on the widely used
PROFIBUS-DP. The transmission technique conforms with the IEC 61158-2 standard and
therefore fulfills the requirements for the type of protection, intrinsic safety.
PROFIBUS-DP defines two types of masters:
4Class 1 master exchanges the data with the configured slaves.
4Class 2 master is used for acyclic data exchange for commissioning and diagnostics pur-
poses.
2 Profile
Basic device functions have been described in profiles by PNO (PROFIBUS user organiza-
tion) to supplement the EN 50170 standard.
The scope of functions of the Type 3730-4 Positioner is consistent with Profile 3.01 for final
control elements. However, it still fulfills all obligatory functions of Profile 3.02, e.g. the auto-
matic implementation on replacing old device models and versions or concerning the con-
densed state according to the NAMUR Recommendation NE 107.

Cyclically transmitted parameters
The following parameters that are transmitted in cyclic data transfer are marked with an as-
terisk (*) in the parameter lists on page 38 onwards.

of the function block.
Range of values defined in PV_SCALE
4RCAS_OUT

Status of the device and measured values
4Checkback
Refer to section 4 for device status.
4Status
Each process value is assigned a status according to the PROFIBUS-PA Profile.
Status of reference variable (hex):
0-3f
40-7f
80-bf
Bad
Uncertain
Good
Refer to section 5 for measured value status.
3.1 GSD files and automatic ID number adaptation
The General Station Description file (GSD file) is included in the scope of delivery for every
PROFIBUS positioner and supplies all information required for the cyclic exchange of process
data (setpoint, status, etc.) with the host system and for configuring the PROFIBUS network.
Each positioner and its GSD file has a unique ID number (ident number) assigned to it. This
allows the host to check the compatibility between the configuration in the system and the
actual device.

The ID number (ident number) of the GSD file must be the same as the ID number of the de-
vice to ensure successful integration.
The Automatic Ident Number Adaption function allows a Type 3785 Positioner to be re-
placed by a Type 3730-4 Positioner without having to replace the GSD file in the host sys-
tem: The configured GSD file/ID number of the positioner is checked by the host (compatibil-
ity test) during the transition to cyclic data exchange. If the positioner is in the compatibility
mode, the GSD file/ID number of the Type 3785 Positioner (Profile 2.0 and Profile 3.0) is
also accepted by the positioner. The positioner changes to cyclic data exchange.
The functions of the active positioner model (active ID number) are only supported by the
process control system for communication.
Example: If the Type 3730-4 Positioner is operated in the compatibility mode for Type 3785
Profile 3.0, the diagnosis telegram then communicates as with Type 3785. Diagnosis bits,
which were first introduced with Profile 3.01, are not set. Additionally, the DI Blocks of
Type 3730-4 cannot be used as they are not available in Type 3785.
Proceed as follows to replace the Type 3785 Positioner with the Type 3730-4 Positioner:
NOTICE
–
The Type 3730-4 Positioner must be mounted and connected properly. Refer to
EB 8384-4 EN.
–
Configuration over PROFIBUS must be performed with the associated EDD or DTM of
Type 3730-4 as this is the only way to access the device parameters.
1. Change the bus address of Type 3730-4 to the same bus address as Type 3785. This can
be done over the PROFIBUS protocol (DEVICE_ADDRESS parameter), using the
TROVIS-VIEW software or in Code 46 in the positioner.
2. Start up the positioner (refer to EB 8384-4 EN).
Note: After initialization (in step 2), the positioner is in compatibility (adaptation) mode
(IDENT_NUMBER_SELECTOR parameter in the Physical Block). Do not change this setting.
