PB340 / PB306 / PB541
Process value indicators and data preset units for PROFIBUS-DP
Product Features:
The PB340 variant is a simple indicator unit for remote display of all actual data
which are available on the connected PROFIBUS network. Arbitrary parameters or
actual values can be read or displayed.
PB306 is a simple data preset unit with front-sided thumbwheel switches. It
allows an easy remote setting of single parameters (e. g. speed setting of a drive)
via fieldbus. By pressing the ENTER button, the actual BCD setting will be
transmitted via PROFIBUS and hold in the polling register for readout.
PB541is a combination of preset switch and indicator. While the BCD switch
allows to make register changes via PROFIBUS, the LED display provides
information about the actual setting of the same or any other register value.
Available Devices:
PB340: Display unit only
PB306: Preset unit only
PB541: Display / Preset combination

1. Safety Instructions and Responsibility
1.1 General Safety Instructions
This operation manual is a significant component of the unit and includes important rules and
hints about the installation, function and usage. Non-observance can result in damage and/or
impairment of the functions to the unit or the machine or even in injury to persons using the
equipment!
Please read the following instructions carefully before operating the device and observe all
safety and warning instructions! Keep the manual for later use.
A pertinent qualification of the respective staff is a fundamental requirement in order to use
these manual. The unit must be installed, connected and put into operation by a qualified
electrician.
Liability exclusion: The manufacturer is not liable for personal injury and/or damage to property
and for consequential damage, due to incorrect handling, installation and operation. Further
claims, due to errors in the operation manual as well as misinterpretations are excluded from
liability.
In addition the manufacturer reserve the right to modify the hardware, software or operation
manual at any time and without prior notice. Therefore, there might be minor differences
between the unit and the descriptions in operation manual.
The raiser respectively positioner is exclusively responsible for the safety of the system and
equipment where the unit will be integrated.
During installation or maintenance all general and also all country- and application-specific
safety rules and standards must be observed.
If the device is used in processes, where a failure or faulty operation could damage the system
or injure persons, appropriate precautions to avoid such consequences must be taken.
1.2 Use according to the intended purpose
The unit is intended exclusively for use in industrial machines, constructions and systems. Non-
conforming usage does not correspond to the provisions and lies within the sole responsibility
of the user. The manufacturer is not liable for damages which has arisen through unsuitable
and improper use.
Please note that device may only be installed in proper form and used in a technically perfect
condition - in accordance to the Technical Specifications (see chapter 7). The device is not
suitable for operation in explosion-proof areas or areas which are excluded by the EN 61010-1
standard.

Pb340_01d_oi_e.doc / Apr-16 Page 4 / 15
1.3 Installation
The device is only allowed to be installed and operated within the permissible temperature
range. Please ensure an adequate ventilation and avoid all direct contact between the device
and hot or aggressive gases and liquids.
Before installation or maintenance, the unit must be disconnected from all voltage-sources.
Further it must be ensured that no danger can arise by touching the disconnected voltage-
sources.
Devices which are supplied by AC-voltages, must be connected exclusively by switches,
respectively circuit-breakers with the low voltage network. The switch or circuit-breaker must
be placed as near as possible to the device and further indicated as separator.
Incoming as well as outgoing wires and wires for extra low voltages (ELV) must be separated
from dangerous electrical cables (SELV circuits) by using a double resp. increased isolation.
All selected wires and isolations must be conform to the provided voltage- and temperature-
ranges. Further all country- and application-specific standards, which are relevant for structure,
form and quality of the wires, must be ensured. Indications about the permissible wire cross-
sections for wiring are described in the Technical Specifications (see chapter 7).
Before first start-up it must be ensured that all connections and wires are firmly seated and
secured in the screw terminals. All (inclusively unused) terminals must be fastened by turning
the relevant screws clockwise up to the stop.
Overvoltages at the connections must be limited to values in accordance to the overvoltage
category II.
For placement, wiring, environmental conditions as well as shielding and earthing/grounding of
the supply lines the general standards of industrial automation industry and the specific
shielding instructions of the manufacturer are valid. Please find all respective hints and rules on
www.motrona.com/download.html --> “[General EMC Rules for Wiring, Screening and
Earthing]”.
1.4 Cleaning, Maintenance and Service Notes
To clean the front of the unit please use only a slightly damp (not wet!), soft cloth. For the rear
no cleaning is necessary. For an unscheduled, individual cleaning of the rear the maintenance
staff or assembler is self-responsible.
During normal operation no maintenance is necessary. In case of unexpected problems, failures
or malfunctions the device must be shipped for back to the manufacturer for checking,
adjustment and reparation (if necessary). Unauthorized opening and repairing can have
negative effects or failures to the protection-measures of the unit.

2. Introduction
The PB340 / PB306 / PB541 series has been designed for display and/or remote preset of single
parameters or registers (e.g. display of actual position or preset of line speed) in systems using
a PROFIBUS-DP network.
These units operate as PROFIBUS-DP slaves according to EN 50 170.
PB340 is a display unit with a 6 decade, 15mm ( 0.59’’ ) size LED-display.
PB306 is a 6 decade BCD thumbwheel switch set with a range of 0 …999 999 *).
PB541 is a combination of both, PB340 and PB306, providing a display and a BCD
thumbwheel switch set *).
All units are built into DIN housings for front panel mounting.
A printout of the GSD file necessary for the use of this unit can be found under
section 6. of this manual. The file itself is available on the CD supplied with
every unit.
You can also download this file at any time from the DOWNLOAD site of our
homepage: http://www.motrona.com
*) With supplementary ordering information “Option VZ000” the unit is available as a 5 decade plus sign
version (setting range -99999 to +99999)

4. Transmission Baud Rate and Unit Address
The unit does not require a Baud rate preset because the baud rate of the network will be
automatically recognized while the communication is starting up. All PROFIBUS-DP baud rates
from 9.6 kbit/s to 12 Mbit/s are supported.
Positions 2…7 of the DIL switch select the unit address, value range 3…126. This address
cannot be changed by the master by the Set_Slave_Address service.
Switch position 1 defines the most significant digit of the front thumbwheel switches to be
transmitted as a numeral or a sign (PB306 and PB541 only).
Version providing a sign (option VZ000) require position 1 to be set to “ON”!

DIL switch settings are only read upon initialization. Changes during
normal operation will not be recognized! After change of DIL switch
settings you must therefore cycle the power supply of the unit.

Pb340_01d_oi_e.doc / Apr-16 Page 9 / 15
5. Communication
During start-up of the communication the master must transmit the configuration data
according to the unit type:
Unit Type:

Meaning:
PB340

When transmitting the parameter data to the unit, the position of the decimal point in display
can be set by the user parameter “decimal point”:

(“State PDU”)
After successful start-up the data communication begins. Both input and output data are
transmitted as signed 32-bit data.
Received output data (PB340, PB541) will be displayed immediately. When the display value
range of -99999 … 999999 is exceeded, “------” will appear in the display.
With PB306 and PB541 units the data of the thumbwheel switch set will be transferred to the
input data buffer upon pressing the ENTER button, and then transmitted with the next cycle.
