2. Interface, general
The ELOTECH – temperature controller is equipped with a PROFIBUS DP interface.
The temperature controller actuates as a slave.
MASTER Profibus - DP Temperature
Controller
The PROFIBUS -interface allows the slave to be monitored and controlled by a PROFIBUS master.
The data transfer between the slave and master takes place with the aid of the PROFIBUS-DP-protocol
acc. to EN 50170.
The communication is always controlled by the PROFIBUS-DP master.
The adress of the slave has to be programmed in the configuration level of the slave.
If there are transmission or other errors detected by the slave, it doesn`t accept this datas.
The old parameter values are still valid.
Slave adjustments:
Unit adress ( Adr ): The adress of the slave 1...255 has to be adjusted into the
configuration level. See parameter „Adr“.
Baudrate bAUd ): 9,6 kBaud ... 12 MBaud (with automatically detected)
Please take attention to the manual of the specific temperature controller.
See: FAQ`s
GDS - data file:
Will be delivered with each slave on disk.

2.1 Line routing, screening and measures to combat interference voltage
This chapter deals with line routing in the case of bus, signal and power supply lines, with the
aim of ensuring an EMC-compliant design of your system.
General information on line routing
- Inside and outside of cabinets
In order to achieve EMC-compliant routing of the lines, it is advisable to split the lines into the
following line groups and to lay these groups separately.
Group A: •shielded bus and data lines (e.g. for PROFIBUS-DP, RS232C and printers etc.)
•shielded analogue lines
•unshielded lines for DC voltages ≥ 60 V
•unshielded lines for AC voltage ≥ 25 V
•coaxial lines for monitors
Group B: •unshielded lines for DC voltages ≥ 60 V and ≥ 400 V
•unshielded lines for AC voltage ≥ 24 V and ≥ 400 V
Group C: •unshielded lines for DC voltages > 400 V
The table below allows you to read off the conditions for laying the line groups on the basis of the
combination of the individual groups.
Line laying instructions as a function of the combination of line groups:
Group A Group B Group C
Group A 1 2 3
Group B 2 1 3
Group C 3 3 1
1) Lines may be laid in common bunches or cable ducts.
2) Lines must be laid in separate bunches or cable ducts (without minimum clearance).
3) Lines must be laid in separate bunches or cable ducts inside cabinets but on separate cable
racks with at least 10 cm clearance outside of cabinets but inside buildings .

Manual R1140-PB-E Release: 2.03 © Elotech GmbH Page 4/16
2.2 Shielding of lines
Shielding is intended to weaken (attenuate) magnetic, electrical or electromagnetic interference
fields.
Interference currents on cable shields are discharged to earth via the shielding bus which is con-nected
conductively to the chassis or housing. A low-impedance connection to the PE wire is
particularly important in order to prevent these interference currents themselves becoming an
interference source.
Wherever possible, use only lines with braided shield. The coverage density of the shield should
exceed 80 %. Avoid lines with foil shield since the foil can be damaged very easily as the result
of tensile and compressive stress on attachment. The consequence is a reduction in the shiel-ding
effect.
In general, you should always connect the shields of cables at both ends. The only way of achie-ving
good interference suppression in the higher frequency band is by connecting the shields at
both ends.
The shield may also be connected at one end only in exceptional cases. However, this then
achieves only an attenuation of the lower frequencies. Connecting the shield at one end may be
more favourable if
• it is not possible to lay an equipotential bonding line
• analogue signals (a few mV resp. mA) are to be transmitted
• foil shields (static shields) are used.
In the case of data lines for serial couplings, always use metallic or metallised plugs and connectors.
Attach the shield of the data line to the plug or connector housing. Do not connect the shield
on the connector of the slave (controller).
If there are potential differences between the earthing points, a compensating current may flow
via the shield connected at both ends. In this case, you should lay an additional equipotential
bonding line.
Please note the following points when shielding:
• Use metal cable clips to secure the shield braiding. The clips must surround the shield over a
large area and must have good contact.
• Downstream of the entry point of the line into the cabinet, connect the shield to a shielding bus.
Continue the shield as far as the module, but do not connect it again at this point!

2.3 Connection guide
Note: Only in PROFIBUS-technologie trained personnel following the safety regulations
may do the PROFIBUS - connections.
It is essential, that one has well experience in installing a profibus device.
You will require the following components to connect the slave:
• Connector for Profibus connection to the slave
• PROFIBUS cable (this cable is generally already installed on site!)
• Diskette with type resp. GSD file
• Project planning tool for the PROFIBUS-Master
It is essential, that you perform the following during connecting in order to ensure that
the slave operates correctly:
PROFIBUS-Connections:
Connect the slave with the PROFIBUS. Take care to the terminals.
See: connection diagram of the specific controller type.
The terminals VP and GND have to be used to connect the terminating-resistors.
There is no further load allowed.
The terminating resistors have to be connected on the first and the last device of the Profibus-
bus.
Terminating-Resistors (Tol. +/-2%): VP +5V

CNT
PROFIBUS – Adjustments:
Adjust the following parameters (slave):
Series R1140:
Parameter „Adress“: Adr: Adjustment of the Profibus-Adress
Parameter „Baudrate“: baud No adjustment possible.
The baudrate will detected and monitored automatically.
Display: „ndEt“ = no baudrate detected.
PROFIBUS - Diagnostic displays:
The diagnostic display works with the help of the decimal-point within parameter „Adr – Adress“.
The slaves of the series R11400 have to be set to „remote operation“ with the parameter „rEno“.
This makes sure, that the parameter values can be written via the profibus.
Dec.point, permanent on: The slave is in the data-exchange-modus.
The communication is ok.
The data-exchange with the master takes place.
Dec.point, flashing: The bus is detected. The slave is waiting until the master has
programmed the slave. This happens automatically.
Dec.point off: The slave is not correct connected to the bus.
E.g.:- Maybe there is a wiring error. - The master is not active.

Manual R1140-PB-E Release: 2.03 © Elotech GmbH Page 6/16
3. Data transfer, general
The Communication:
The master sends it´s data to the slave.
After this the slave sends an answer to the PROFIBUS DP - master.
This takes place cyclic and will be controlled by the master.
The configuration of the slave takes place with the help of the GSD-file.
The following moduls are available for the slave:
1. Process reflection: Module: „1 – channel process data“
2. Configuration channel: Module: „parameter channel“
3. Process reflection and Configuration channel:Module: „1 – channel process + parameter“
3.1 Process reflection
Parameter transfer according to the process reflection modul:
3.1.1 From master to slave:
Transfer of Setpoint 1 and Status word 1
Byte 1 Byte 2 Byte 3
Setpoint 1
High Byte
Setpoint 1
Low Byte
Control byte
WARNING: Every change of the setpoint is stored in the internal
nonvolatile memory. It permits max. 1.000.000 write
cycles!
Setpoint / process value: The parameter value consists out of 2 data bytes within the process
reflection.
Setpoint and actual process values will be transmitted always with a
decimal digit, although the measuring range has no decimal digit.
Example: °C Dec. Hex. High-Byte Low-Byte
Measuring range with dec. point: act. value 23,0 230 00E6 00 E6
Measuring range with dec. point: setpoint 170,0 1700 06A4 06 A4
Measuring range without dec. point: act. value 23 230 00E6 00 E6
Measuring range without dec. point: setpoint 170 1700 06A4 06 A4
Control byte: The parameter consist out of one data byte:
Bit 0: controller / slave 0 = on, 1 = off
Bit 1: self tuning 0 = off, 1 = on
Changing this bit from „0“ to „1“ will force the controller to do one selftuning action.
Set this bit to „0“, before starting a new selftuning action.
Bit 2: 0
Bit 3: actual setpoint 0 = setpoint SP1, 1 = setpoint SP2
Bit 4: 1 = delete warning „selftuning error“ into the status byte
Bit 5: 0
Bit 6: 0
Bit 7: 1 = delete warning „system error“ into the status byte
