5.3 Communication
5.3.1 Block model of PROFIBUS-PA/-DP
In the PROFIBUS configuration, all the device parameters are categorised according to
their functional properties and tasks and are generally assigned to three different
blocks. A block may be regarded as a container in which parameters and the
associated functionalities are contained.
A PROFIBUS device has the following block types (see Fig. 8):
• Ê*ÞÃV>ÊVÊ`iÛViÊLV®
The Physical Block contains all device-specific features of the unit.
• "iÊÀÊÀiÊ/À>Ã`ÕViÀÊVÃ
The Transducer Block contains all the measuring and device-specific parameters of
the device. The measuring principles (e.g. conductivity, temperature) are depicted in
the Transducer Blocks in accordance with the PROFIBUS Profile 3.0 Specification.
• "iÊÀÊÀiÊvÕVÌÊLVÃ
A function block contains the automation functions of the device. The transmitter
contains Analog Input blocks by means of which the measured values can be scaled
and examined for limit value overshoot.
A number of automation-related tasks can be implemented with these blocks. In
addition to these blocks, a transmitter can have any number of additional blocks, for
example several Analog Input function blocks if the transmitter makes more than one
process variable available.

Physical Block (device block)
A Physical Block contains all the data that uniquely identifies and characterises the
transmitter. It is an electronic version of a nameplate on the transmitter. Parameters of
the Physical Block include the device type, device name, manufacturer ID, serial
number, etc.
A further task of the Physical Block is the management of general parameters and
functions that have an influence on the execution of the remaining blocks in the
transmitter. The Physical Block is thus the central unit that also checks the device status
and thereby influences or controls the operability of the other blocks and thus also of
the device.
Write protection
• "ÃÌiÊ>À`Ü>ÀiÊÜÀÌiÊ«ÀÌiVÌ
By pressing the & and / keys simultaneously, you can lock the device for on-site
configuration operations.
Use the
; and 3 keys to unlock the device. More information can be found in the
SmarTec S Operating Instructions BA 207C/07/en under "Locking/Unlocking
keyboard" (Chapter 5: operation).
• >À`Ü>ÀiÊÜÀÌiÊ«ÀÌiVÌÊÛ>Ê*," 1-
The HW_WRITE_PROTECTION parameter indicates the status of the hardware write
protection. The following statuses are possible:
1: Hardware write protection enabled, device data cannot be overwritten
0: Hardware write protection disabled, device data can be overwritten
• -vÌÜ>ÀiÊÜÀÌiÊ«ÀÌiVÌ
You can also set software write protection to prevent all parameters from being
acyclically overwritten. You can do so by making an entry in the WRITE_LOCKING
parameter. The following entries are permitted:
2457: Device data can be overwritten (factory setting)
0: Device data cannot be overwritten
LOCAL_OP_ENABLE parameter
You can use the LOCAL_OP_ENABLE parameter to permit or lock local operation at the
device. The following values are possible:
•0: Deactivated.
Local operation is locked. You can only change this status via the bus.
The code 9998 is displayed in the local operation. The transmitter behaves just as with
hardware write protection via the keyboard (see above).
•1: Activated.
Local operation is active. However, commands from the master have a higher priority
than local commands.
 Note!
Local operation is automatically activated if communication should fail for longer than
30 seconds.
If communication fails when local operation is locked, the device will immediately go to
the locked status as soon as communication is functioning again.
PB_TAG_DESC parameter
You can set the client-specific device number (tag number) via:
•Local operation in menu field I2 (INTERFACE function group) or via
•PROFIBUS parameter TAG_DESC of the Physical Block.
If you change the tag number via one of the two options, the change can also be seen
immediately at the other position.

FACTORY_RESET parameter
You can reset the following data via the FACTORY_RESET parameter:
1 all data to PNO default values,
2506 transmitter warm start,
2712 bus address
32768 calibration data,
32769 setting data.
Via local operation you can either reset all data to the factory settings or delete the
sensor data in menu field S10 (SERVICE function group).
IDENT_NUMBER_SELECTOR parameter
You can use the IDENT_NUMBER_SELECTOR parameter to switch the transmitter
between three operating modes, which each have a different functionality in relation to
the cyclic data:
(See also table on Device Master Files on Page 23).
DIAGNOSIS and DIAGNOSIS_EXTENSION parameters
The tables for the DIAGNOSIS and DIAGNOSIS_EXTENSION parameters (system error
messages) can be found in section 9 “Troubleshooting”.
IDENT_NUMBER_SELECTOR Functionality
0 Cyclic communication only possible with Profile GSD. Only
standard diagnosis in cyclic data.
1 (default) Full functionality with Profile 3.0 and extended diagnosis in cyclic
data. The manufacturer-specific GSD is required.

Analog Input Block (function block)
In the Analog Input function block, the process variables (conductivity and temperature)
coming from the Transducer Block are prepared, in terms of instrumentation and
control, for the subsequent automation functions, (e.g. scaling and limit value
processing). There are two Analog Input function blocks available for the SmarTec S
PROFIBUS transmitter.
Signal processing
The diagram shows a schematic of the internal structure of an Analog Input function
block:

The Analog Input function block receives its input value from the Analyser Transducer
Block. The input values are permanently assigned to each Analog Input function block:
•Main measured value (Main Process Value) – Analog Input function block 1 (AI 1)
•Temperature measured value (temperature) – Analog Input function block 2 (AI 2)
SIMULATE
In the SIMULATE parameter group you can replace the input value with a simulation
value and activate simulation. By specifying the status and the simulation value, you can
test the reaction of the automation system.
PV_FTIME
In the PV_FTIME parameter you can dampen the converted input value (primary value
= PV) by specifying a filter time. If a time of 0 seconds is specified, the input value is not
dampened.
MODE_BLK
The MODE_BLK parameter group is used to select the operating mode of the Analog
Input function block. By selecting the MAN (manual) operating mode, you can directly
specify the OUT output value and the OUT status.
The most important functions and parameters of the Analog Input Block are listed
below.
A table displaying the functions of the Analog Input Block can be found on Page 33.

Selecting the operating mode
The operating mode is set by means of the MODE_BLK parameter group. The Analog
Input function block supports the following operating modes:
•AUTO (automatic mode)
•MAN (manual mode)
•O/S (out of service)
Selecting the units
The system unit for one of the measured values can be changed via Commuwin II in the
Analog Input Block.
Any change to the unit in the Analog Input Block does not initially have any influence on
the measured value being transferred to the PLC. This ensures that an abrupt change
cannot have any influence on the subsequent control. If the unit change has an
influence on the measured value, activate the SET_UNIT_TO_BUS function using
Commuwin II.
Another way of changing the unit is to use the PV_SCALE and OUT_SCALE parameters
(see Page 18 "Rescaling the input value").
OUT
The OUT output value is compared with warning limits and alarm limits (e.g. HI_LIM,
LO_LIM), which can be entered via various parameters. If one of these limit values is
violated then this triggers a limit value process alarm (e.g. HI_ALM, LO_ALM).
OUT Status
The status of the Analog Input function block and the validity of the OUT output value
are relayed to the downstream function blocks by means of the status of the OUT
parameter group. The following status values can be displayed:
•GOOD_NON_CASCADE
The OUT output value is valid and can be used for further processing.
•UNCERTAIN
The output value OUT can only be used for further processing to a limited extent.
•BAD
The OUT output value is invalid. Occurs when the Analog Input function block is
switched to the O/S operating mode (Out of Service) or in the event of a serious error
(see status codes Page 22 and system or process error messages in the Operating
Instructions BA 207C/07/en).
In addition to the device-internal error messages, other device functions have an
influence on the status of the OUT value:
•Automatic hold
If "Hold" is switched on, the OUT Status is set to BAD not specific (0x00).
•Calibration
During calibration, the OUT Status is set to the UNCERTAIN sensor calibration value
(0x64) (even when hold is switched on).

Simulation of input/output
You can simulate the input and output of the function block by means of various
parameters of the Analog Input function block:
1. Simulating the input of the Analog Input function block:
The SIMULATION parameter group can be used to specify the input value
(measured value and status). Since the simulation value runs through the entire
function block, you can check all the parameter settings of the block.
2. Simulating the output of the Analog Input function block:
Set the operating mode in the MODE_BLK parameter group to MAN and directly
specify the desired output value in the OUT parameter.
Measured value simulation in local operation
In the case of measured value simulation in local operation, the status UNCERTAIN –
simulated value is relayed to the function blocks. This triggers the failsafe mechanism
in the AI blocks.
Error response (FSAFE_TYPE)
If an input or simulation value has the status BAD, the Analog Input function block uses
the error response defined in the FSAFE_TYPE parameter. The FSAFE_TYPE parameter
offers the following error response options:
•FSAFE_VALUE
The value specified in the FSAFE_VALUE parameter is used for further processing.
•LAST_GOOD_VALUE
The last good value is used for further processing.
•WRONG_VALUE
The current value is used for further processing, despite the BAD status.
The default is the setting (FSAFE_VALUE) with value “0”.
 Note!
Error response is also activated if the Analog Input function block is set to the “OUT OF
SERVICE” operating mode.
Rescaling the input value
In the Analog Input function block, the input value or input range can be scaled in
accordance with the automation requirements.
Example:
•The system unit in the Transducer Block is °C.
•The measuring range of the device is –10 .. 150 °C.
•The output range to the automation system should be 14 °F ... 302 °F.
•The measured value from the Transducer Block (input value) is rescaled linearly via
the input scaling PV_SCALE to the desired output range OUT_SCALE.
•Parameter group PV_SCALE
PV_SCALE_MIN (V1H0) –10
PV_SCALE_MAX (V1H1) 150
•Parameter group OUT_SCALE
OUT_SCALE_MIN (V1H3) 14
OUT_SCALE_MAX (V1H4) 302
OUT_UNIT (V1H5) [°F]
The result is that with an input value of 25 °C, for example, a value of 77 °F is output via
the OUT parameter (see Fig. 10 below).

Limit values
You can set two warning limits and two alarm limits for monitoring your process. The
status of the measured value and the parameters of the limit-value alarms are
indicative of the measured value’s relative position. You also have the option of
defining an alarm hysteresis in order to avoid frequent changes of the limit-value flags
and frequent enabling/disabling of alarms.
The limit values are based on the OUT output value. If the OUT output value exceeds or
undershoots the defined limit values, the automation system is alarmed via the limit
value process alarms (see below).
The following limit values can be defined:
– HI_LIM, HI_HI_LIM
– LO_LIM, LO_LO_LIM
Alarm detection and processing
Limit value process alarms are generated by the Analog Input function block.The
status of the limit value process alarms is communicated to the automation system by
means of the following parameters:
– HI_ALM, HI_HI_ALM
– LO_ALM, LO_LO_ALM
