<3. Getting Started>
Getting Started
PROFIBUS PA is fully dependent upon digital communication protocol (EN 50170 Volume 2 and
IEC 61158 for IS areas, PROFIBUS PA) and differs in operation from the conventional 4 to 20
mA transmission communication protocol. It is recommended that novice users use field devices
in accordance with the procedures described in this section. The procedures assume that field
devices will be set up on a bench or an instrument shop.
3.1
Connection of Devices
The following instruments are required for use with PROFIBUS PA devices:
• Power supply:
PROFIBUS PA requires a dedicated power supply. It is recommended that current capacity
be well over the total value of the maximum current consumed by all devices. Power is
supplied by a DP/PA coupler.
• Terminators:
PROFIBUS PA requires two terminators. A terminator shall be located at each end of the
trunk cable.
• Field devices:
Connect the PROFIBUS PA communication type field device. Two or more transmitters or
other field devices can be connected.
• DP/PA Couplers:
PROFIBUS PA requires DP/PA couplers which convert the RS-485 signals to the IEC
61158-2 signal level and power the field devices via the PROFIBUS PA.
• Cable:
Refer to Table 2.2.
For applications in intrinsically safe areas, the transmission method defined in IEC 61158-2 is
used with PROFIUS PA The transmission rate in this case is 31.25 k bit/s. DP transmission via
RS-485 to IEC 61158-2 is implemented with the network components (DP/PA coupler or DP/PA
link.)
Connect the devices as shown in Figure 3.1. Connect the terminators at both ends of the trunk,
with a minimum length of the spur laid for connection.
The polarity of signal and power must be maintained.

NOTE
Before using a PROFIBUS PA configuration tool other than the existing host, confirm it does not
affect the loop functionality in which all devices are already installed in operation. Disconnect the
relevant control loop from the bus if necessary.
CAUTION
Connecting a PROFIBUS PA configuration tool to a loop with its existing host may cause
communication data scrambles resulting in a functional disorder or a system failure.
3.2
Host Setting
To activate PROFIBUS PA, the following settings are required for the host.
CAUTION
Do not turn off the power of the device immediately after setting. When the parameters are saved
to the EEPROM, the redundant processing is executed for an improvement of reliability. If the
power is turned off within 60 seconds after settings are made, the modified parameters are not
saved and the settings may return to their original values.
For cyclic data communication a GSD file is required. This file contains all necessary information
to start this type of communication. Please make sure the GSD file is in the right directory so the
information is available to the HOST. Refer to the HOST’s manual for guidance.
For acyclic communication several configuration tools can be used. Each communication tool
requires its own device driver. We currently support only Siemens Simatic PDM and Yokogawa
FieldMate. All parameter lists and methods described in this manual are based on this acyclic
communication tool. Please make sure the device driver is in the proper directory. Most HOST
systems come with an “install device driver” package which places all required files in the
designated folders.
3.3
Bus Power ON
Using the host device display function, check that the FLXA21 is in operation on the bus.
Unless otherwise specified, the following settings are in effect when shipped from the factory.
If no FLXA21 is detected, check the available address. Please set all addresses of the devices in
advance or separately connect each FLXA21 and set a different address for each. Make sure to
note the address after changing it as from this point on the device can only be accessed through
this address.
3.4
Bus Address Setup
This section describes the procedure to set Bus Address in the transmitter. Every device in
PROFIBUS PA must be assigned a unique address in the range of 0 (0x00) to 126 (0x7e). If it is
not specified at the time of order, 126 (0x7e) is the factory default. Do not change to 0, 1 or 2 as
these are used by master devices.
You can change the bus address using a communication tool (e.g., PROFI captain). For details,
see the instruction manual for the communication tool.

Notes When Using the FLXA21-SC
Concentration Table (when using FieldMate)
The FLXA21-SC concentration table can be read from and written to using the CONC_TABLE_
CONCENTRATION_1 to CONC_TABLE_CONCENTRATION_21 and CONC_TABLE_
CONDUCTIVITY_1 to CONC_TABLE_CONDUCTIVITY_21 parameters of the transducer block.
However, when using FieldMate, note the following points.
The default concentration table values are “Not a Number”. On the device screen, they appear as
blank. On FieldMate, “IEEE: NOT A NUMBER” is displayed.
Values set to “Not a Number” cannot be changed from FieldMate.
If you want to write the concentration table from FieldMate, first set all the items in the
concentration table to some value from the device screen.
3.6PRIMARY/SECONDARY/TERTIARY/
QUATERNARY_VALUE Value Assignment
Measurement values are assigned to PRIMARY_VALUE, SECONDARY_VALUE, TERTIARY_
VALUE, and QUATERNARY_VALUE from the device screen.
To set PRIMARY_VALUE, choose Commissioning > Output setup > Output, and then set the
Process parameter item on the mA (Output) screen.
For others, choose Commissioning > Advanced setup > Communication > HART, and on the
HART setup screen, set SECONDARY_VALUE with the SV item, TERTIARY_VALUE with the
TV item, and QUATERNARY_VALUE with the QV item.
CAUTION
Be sure to use the default values for the following settings.
Changing them may disrupt communication.
Commissioning > Advanced setup > Communication screen
Default value: HART
Commissioning > Advanced setup > Communication > HART setup screen
Item name:
Network address
Default value: 0
If you want to change the settings from the device, first change Transducer Block Mode (refer
also to tables in chapter 6 because not all parameters need OS to allow a change) to Out of
Service.
If you want to load the factory settings or change the language, first change Physical Block Mode
(refer also to tables in chapter 6 because not all parameters need OS to allow a change) to Out of
Service.
Note that when you do, the FLXA21 will restart.

Explanation of Basic Item
4.1
Reading cyclic parameters
In general, slave devices exchange data cyclically with the master (class 1, e.g. PLC). The
FLXA21 (slave) gets the data from the sensor, makes some calculations and makes the outcome
available through analog input blocks. The controller device (Master) requests for these process
values, makes some calculation (PID, ratio) and sends the result to an actuator. The FLXA21
contains three analog input blocks and therefore three Process values for cyclic data transfer.
The master class 1 device gets the information (of the FLXA21) by consulting the GSD file. A
device specific GSD file should be available for each device and should have an unique identifier.
All information necessary for cyclic data transfer is described in the GSD file. Refer to the manual
of the Master Class 1 device for these folders. With these files, the Master Class 1 devices are
able to start cyclic data transfer.
4.2
Integration of GSD file and IDENT Number
The GSD file and IDENT Number are necessary for PROFIBUS PA communication. Before
starting communication, the device must be specified by the GSD file in the host system and the
IDENT Number of the device.
The PROFIBUS PA device has a profile IDENT Number and a device-specific IDENT Number.
There are GSD files which correspond to each number. The profile GSD file is a general-purpose
file which is defined by the kind and number of function blocks of the device. This file helps
improve the compatibility among devices.
By setting the PROFIBUS PA IDENT Number (IDENT_NUMBER_SELECTOR) parameter of the
physical block, the IDENT Number will be linked with the corresponding GSD file.

Beforehand one must configure which information will be exchanged.
There are two kinds of configurations possible. The Identifier byte (or short identifier) and the
Extended Identifier Format (or long identifier). The FLXA21 supports both kinds of configurations.
The user can choose either “Analog Input (short)” or “Analog Input (long)” and will end up with the
same result.
The function blocks of the FLXA21 are in a specific order. The configuration of the cyclic data
should be done in the same order.

Function Block Parameters
Function block parameters can be read from the host or can be set. For a list of the parameters of
blocks held by the FLXA21, refer to “3.6PRIMARY/SECONDARY/TERTIARY/QUATERNARY_
VALUE Value Assignment”. The following is a list of important parameters with a guide how to set
them.
nOutline
This chapter describes brief explanation of the AI function block.
n Target Mode
The Target modes permitted for the AI function block are Automatic (Auto), Manual (Man), and
Out of Service (O/S). When the Target mode of PB (Physical Block) is Out of Service (O/S),
Actual is Out of Service (O/S) even if Automatic (Auto) or Manual (Man) is written to Target.
n Actual mode
Many parameters require a change of the mode of the function block to O/S (Out of Service)
when their data is changed. To change the mode of the function block, its Target Mode
(TARGET_MODE) needs to be changed. The Actual Mode (MODE_BLK) is comprised of the
three sub-parameters:
(1) Actual (Actual mode): Indicates the current operating condition.
(2) Permit (Permitted mode): Indicates the operating condition that the block is allowed to take.
(3) Normal (Normal mode): Indicates the operating condition that the block will usually take.
These mode parameter are very important as it gives the state of the block. In O/S (Out_Of_
Service) mode the block is out of operation. In this mode it is allowed to update parameters.
Manual mode gives the operator the possibility to manually update a selected number of
parameters (values, scaling e.g.) in order to test the system. In automatic mode the function
block is executed and block parameters are automatically updated.
Under normal operating circumstances, set the Auto mode for normal operation. Auto mode is
the factory default.
NOTE
The actual mode is changed by setting the target mode. When the physical block mode is set to
OOS all function blocks are set to OOS mode.
nCHANNEL
Channel is the parameter to select the signal which is calculated in SENSOR Transducer Block.
The values are assigned to channels.
For the FLXA21 three or four channels are available.
For the FLXA21, you can select from the PRIMARY, SECONDARY, TERTIARY, QUATENARY
values assigned to the Transducer Block.
For details on how to assign measurement items to parameters, refer to “3.6
PRIMARY/
SECONDARY/TERTIARY/QUATERNARY_VALUE Value Assignment”.
The following table shows the measurement items that you can select and their default values.

n Fail Safe Mode
Fail Safe Mode defines the Output Value and Status (Quality) when status of input signal to AI
function block or Totalizer function block is BAD.
This function is valid only when Actual Mode of AI function block is in “AUTO”
n Output Value (OUT)
The function block parameter OUT contains the current measurement value in a vendor specific
or configuration adjusted engineering unit and the belonging status in Auto Mode. Also contains
the value and status set by an operator in Man Mode.
n Simulation (SIMULATE)
Simulation parameter is to simulation mainly for checking arbitrarily set the value and input status
from SENSROR Transducer block.
n PV Scale (PV_SCALE)
Conversion of the process variable into percent using the high and low scale values.
n Linearization type (LIN_TYPE)
Linearization type of output signal can be select from Linear or Square root. Linearization type
of AI function block can apply to have different output mode for display and output signal. (For
example, Display mode: Square root, Output mode: Linear)
n Out Scale (OUT_SCALE)
Scale of the process variable. This parameter contains the values of the lower limit and upper
limit effective range, the code number of the engineering unit of process variable and the useful
number of digits on the right hand side of the decimal point.
n Filter Time Const (PV_FTIME)
Damping time of the process variable.

Setting the AI Function Blocks
The AI function block is a unit of the software.
During execution, it incorporates data from the SENSOR transducer block. After execution, it
updates analog outputs and processes newly generated alarms. AI function blocks can provide a
discrete output which shows the status of LO, LO_LO, HI, or HI_HI. In terms of function, there is
no difference between the three AI function blocks provided in FLXA21.
n Function Blocks
The AI function block, via the Channel, incorporates analog signals from the transducer block,
performs scaling processing, filtering, signal linearization, fail safe control and alarm processing
before outputting. It has the function to generate a discrete output. Figure 4.1 presents the AI
function block.

In-Process Operation
This chapter describes the procedure performed when changing the operation of the function
block of the analyzer in process.
5.1
5.2
Mode Transition
When the function block mode is changed to Out_Of_Service, the function block pauses.
When the function block mode is changed to Manual, the function block suspends updating of
output values. In this case alone, it is possible to write a value to the OUT parameter of the block
for output.
Generation of Alarm
n Indication of Alarm
When the self-diagnostics function indicates that a device is faulty, a diagnostic message
(DIAGNOSIS or DIAGNOSIS_EXTENSION) is issued from the physical block. When a
diagnostic message is detected in each function block or a diagnostic message in the process
value (process alarm) is detected, a diagnostic message is issued from each block.
For details of alarm, refer to “n Device status” on page 6-14 .

n Status of Each Parameter in Failure Mode
Status has Classic Status and Condensed Status.
Classic Status is a conventional alarm and does not support the NAMUR NE107. Condensed
Status is an alarm which was added to PA Profile 3.01 or later and supports the NAMUR NE107.
The following standard categories of instrument diagnostics are defined for the NAMUR NE-107.
F (Failed):
An alarm category that indicates a failure has occurred in the instrument or in its peripheral
devices.
C (Check Function):
An alarm category that indicates that a detected failure is a temporary event.
S (Off Specification):
An alarm category that indicates that the detected failure was caused by the instrument
being used outside of its range or because a discrepancy has occurred between the set
value and measured value. The alarm was caused either by the instrument or process state.

<5. In-Process Operation>
M (Maintenance):
An alarm category for a detected failure that has a low level of urgency but is a failure
that could develop into a problem causing restrictions in instrument functionality in some
environments.
Classic Status and Condensed Status can be switched by using the Condensed Status/
Diagnosis (PB.COND_STATUS_DIAG) parameter.
5.3
Simulation Function
It is possible to conduct testing for the downstream function blocks or alarm processes. Following
description is how to use and how to set parameters of this function.
n AI Function Blocks
When the parameters are set in the transducer block, it is necessary to set parameters as shown
in Table 5.1 in the AI function blocks. When Simulate_Enabled in AI function blocks described
at Table 5.1 is set to “1: Enabled”, the each AI function block that set this parameter uses the
simulation value instead of the data from the transducer block.

Write lock (Write-protect) function
The transmitter is provided with a write lock (write-protect) function to restrict write operations to
blocks and prevent inadvertent writing of parameter data. To enable this function, use the write
lock switch (Hard W Lock) or the WRITE_LOCKING (Physical block index 34) (Soft W Lock).
The CPU assembly of the transmitter is provided with a write lock switch (refer to Figure 2.3).
When the write lock switch is disabled, set 0 (protected) for WRITE_LOCKING (index 34) of the
physical block to enable the write lock function.
These parameters and issue shall control the parameter access as defined in Table 5.2.
