The ND800PA is shipped with one CD-ROM disc. The CD-ROM disc contents;
• GSD file
• Simatic PDM driver
• Installation, Maintenance and Operation instructions (IMO)
• Users Guide
3.1 GSD file
GSD file is needed for the PROFIBUS master (class 1) to be able to configure the cyclic DP
communication between the master and the slave. The Profibus master could be a DCS or
PLC from any vendor. All of these systems have their own, separate configuration tools. All of
these tools understand the ND800PA GSD file.
The following example (figures 1-5) describes how to add the NEL_052D.GSD file to the
Siemens Step 7 Hardware catalog as well as to the hardware project.

ND800PA GSD modules
4 ND800PA GSD modules
The control communication is basically as follows; PLC/DCS writes the valve position setpoint
to the ND800PA and reads the position measurement from the ND800PA. This
communication is configured by the GSD modules.
GSD module is a set of data, which the ND800PA and DCS/PLC exchanges cyclically until the
end of the world. The GSD modules are listed in the GSD file. The ND800PA GSD file name is
Nel_052d.gsd. During the DCS/PLC configuration, the configuration software, such as
Siemens Simatic Step 7, reads the Nel_052d.gsd file and asks user, which GSD module
should be used.
The ND800PA has following GSD modules;
• SP
• SP,READBACK,
• SP,CHECKBACK
• SP,READBACK, CHECKBACK
• RCAS _IN,RCAS_OUT
• RCAS_IN,RCAS_OUT.CHECKBACK
• SP,RB,RC_I,RC_O, CB
Abbreviations; RB=READBACK, RC_I=RCAS_IN, RC_O=RCAS_OUT, CB=CHECKBACK
For compatibility reasons the modules are represented in both Identifier Byte format and in
Extended Identifier Format.
SP is the valve position setpoint in the AUTO mode. The ND800PA Analog Output Block
default target mode is AUTO. The range is 0-100%.
READBACK is the valve position measurement. The range is 0-100%.
contains the limit switch information. The values are:
1 = closed
2 = opened
3 = intermediate
If the limit switches are not installed, the
measurement sensor as follows:
1 = closed, Position <= 2%
2 = opened, Position >=98%
3 = intermediate, 2 < Position < 98 value is determined from the position
RCAS_IN is the valve position setpoint in the Remote Cascade mode. Before this setpoint is
used, the Analog Output Block (AO) actual mode has to be the RCAS mode. This requires as
follows;
• AO block target mode must be RCAS.
• The DCS/PLC has to go through the remote cascade initialization sequence with the
ND800PA. This is done by using the STATUS bytes of the RCAS_IN and RCAS_OUT
signals.
RCAS_OUT feeds back the SP or RCAS_IN, depending on the mode.
CHECKBACK is a diagnostic signal. All control systems has their ways to convert this
standard bit-information to human readable alert messages. See table 1.

ND800PA GSD modules
In addition to the CHECKBACK, the ND800PA has two more diagnostic signals. These signals
are not included in the GSD modules.
DIAGNOSIS contains standard diagnostic information (See table 3). This parameter is
available to DCS/PLC if it supports a DP service called ddlm_slave_diag. The idea here is
that this parameter is not polled cyclically, but whenever new information is available, the
ND800PA rises a diagnostic flag (in cyclic communication). When DCS/PLC sees that flag, it
reads the DIAGNOSIS parameter by using the ddlm_slave_diag service.
DIAGNOSIS EXTENSION is manufacturer specific extension to the DIAGNOSIS (See table
4). This parameter is included in the ddlm_slave_diag service only if the PROFIBUS Ident
Number is selected to be Manufacturer specific.

The ND800PA Simatic PDM user interface is divided in three main categories.
• Parameter groups. The static configuration parameters are grouped in logical groups. The
parameters in the groups are presented in the parameter table. The parameter table can
be saved to the Hard Disk. The saved parameter table can be compared with the
parameters in the device.
• Device menu. Device menu contains high-level device functions like Calibration.
• View menu. Unlike the Device menu, the View menu contains only passive elements such
as measured value displays.
In the following paragraphs the ND800PA functionality is described in means of Parameter

Dead Angle Compensation
This adjustment is used to change the valve travel from fully closed to a desired travel with a
small change in input signal near the 0% value of the input signal range. This can be used to
compensate dead angle in a ball or segment valve such that it is equal to the ao adjustment in
conventional Neles positioners. The ac, adjustment is used especially with small ball valves
which require a turn of several degrees from the closed position before any flow through the
valve is perceptible. Suitable ac, values for Neles segment and ball valves can be found in /1/.
See figure 13.

Set this parameter to the average value of the positioner supply pressure. Supply pressure is
used to calculate the load factor.
Travel Deviation Warning Limit
Warning limit for the deviation between the setpoint and actual travel.
Travel Deviation Alarm Limit
Travel deviation alarm limit.
Load Factor Warning Limit
Load factor warning limit. In the case of a single acting actuator, the load factor shows the
actuator load with respect to the present spring force, i.e., a load factor of 100% indicates that
the actual load may exceed the spring force. For double acting actuators, the load factor
shows the actuator load with respect to the user-given supply pressure level, i.e., a load factor
of 100% indicates that the actual load may exceed maximum attainable pressure difference
being equal to the supply pressure. A high load factor indicates the presence of high friction or
an undersized actuator if the given supply pressure is equal to actual supply pressure level.

5.6.2 Flow characterization
When optimizing process control loop performance a linear relationship between the flow and
valve position setpoint signal should be established. This can be achieved by using this flow
characterization design tool.
Valve inherent flow characteristics curve tells the (normalized) valve capacity (effective flow
cross-section) versus the valve position. This curve is specific to the physical valve design.
Valve installed flow characteristics curve tells the (normalized) flow versus the valve position.
This curve is the result of the inherent flow characteristics curve and the process pressure
behavior.
The flow characterization design tool changes the valve inherent flow characteristics curve to
any desired curve. Current inherent characteristics table tells the flow characteristics
without any signal modifications. Desired inherent characteristics table tells the desired
characteristics. Based on this information, the tool calculates the required signal modification,
Signal modification table, which is as well user editable.
Current inherent characteristics table (Figure 19)
This table tells the inherent flow characteristics without any signal modifications (flow
characterization is off). The table values are the relative flow coefficients at corresponding
valve openings.
Desired inherent characteristics table (Figure 20)
This table tells the desired inherent flow characteristics. The table values are the relative flow
coefficients at corresponding valve openings.

Characterization (Figure 21)
This parameter controls the characterization. Options are:
• Off - Shows the active state or turns the characterization off.
• On - Shows the active state or turns the characterization on.
• Calculate new Signal mod table from CURRENT and DESIRED tables
• Clear Signal mod table
• Enable new Signal mod table using all table values
• Enable new Signal mod table using every second table value. This option fills the missing
points using linear interpolation.

NOTE:
If the installed flow characteristics curve is known, this tool can ALTERNATIVELY be used to
modify the installed characteristics. In this case all the words INHERENT in the tool must be
understood as INSTALLED. The installed curve can be found by a simple process test or it
can be calculated by the Nelprof software.
NOTE:
The dead angle compensation is done before the characterization.

5.6.3 Valve test
To ensure that the control valves are working properly they can be tested with the Testing
function. Two control valve performance tests, the Hysteresis loop and Step response, can be
run with the device. The Step response test tells how rapidly the valve reacts to the input sig-
nal, while the Hysteresis loop test tells how large is the dynamic hysteresis + dead band,
which indicates friction quantity. The control valve test results can be used to diagnose the
condition of the control valve, thus showing the need for possible future maintenance work.
Running control valve tests is, therefore, very important predictive maintenance work and en-
sures optimal performance of the control valve in every situation. Note that control valve test-
ing affects process control by driving the control valve independently of the input signal from
the control system !
The valve test control page is presented in figure 23. Before starting the test, adjust the test
settings. Test can be started by pressing the button "Start test". Test can also be cancelled
any time by pressing the button "Cancel test". The dialog "Test state" shows the current sate
of the test procedure.
The graphic window shows the on-line measurements; Positioning value and Feedback value.
The window axis can be adjusted by double clicking the window. The purpose of this window
is just for monitoring the test execution. This window is not intented to be used to examine
the test results, since the sampling time is too long and not constant.
After successful' test, the test results can be found from the pages Step response test results
(fig 24) and Hysteresis test results (fig 25). The data for these graphs is collected by the
device itself. The data size is 50 measurement points.

write access to all writeable parameters of a device.
• SW Write Locking. Protects all acyclic write access to all writeable parameters of a device
except this SW Write Locking one. Selections are On and Off.
• Local Operation. Enables/Disables the local operation of the device. The operation of the
host has higher priority then the local terminal one. If communication fails for a time greater
30 sec, local operation will be enabled automatically. Communication failure is defined here
as absence of cyclic and acyclic communication for the specified time period. If Local
Operation parameter is disabled and the communication is working again, then the device
switch back to remote operation.
