General Information 1
Section 1: General Information
Section 1: General Information
The Standardized PROFIBUS DP system is available for all Bettis RTS Series of actuators.
This interface is a hardware option and should already be known when ordering the actuator.
Retrotting is possible but should only be performed by a skilled Emerson technician or by
specially trained personnel.
PROFIBUS-DP denes the technical and functional characteristics of a serial eldbus
system, with which a set of distributed, digital automation devices can be networked with
one another. PROFIBUS-DP distinguishes between master and slave devices and is designed
to exchange data at the eld level.
This is where central control devices, such as PLCs and PCs, communicate with distributed
eld devices via a fast serial connection.
Data exchange with these decentralised devices is carried out cyclically. The communication
functions necessary to do this are dened by the PROFIBUS-DP basic functions according
to EN 50170.
Master devices control the data trafc on the bus. A master can send messages without an
external request. In the PROFIBUS protocol, masters are also called active participants.
Slave devices such as BETTIS RTS actuators are peripheral devices. Typical slave devices are
input/output devices, valves, actuators and transmitters. They are not given active bus
access authorisation, i.e. they are only allowed to acknowledge received messages, or, at
the request of a master, transmit messages to it. Slaves are also called passive participants.
The master cyclically reads the input information from the slaves and cyclically writes the
output informa- tion to the slaves. In addition to this cyclic data transmission of the process
image, PROFIBUS-DP also offers powerful functions for diagnostics and commissioning
purposes. Monitoring functions on the master and slave sides monitor the data trafc.
The transmission technology is based on an RS-485 connection via a shielded twisted-pair
cable. Bettis RTS series support baud rates up to 1.5 Mbit/s.
Only cables in accordance with standard DIN 19245 and/or EN 50170-2, cable type A, may
be used for PROFIBUS-DP cabling.
Depending on the transmission speed, the following segment lengths are permitted:
Table 1.
Transmission Speed Segment Length
9.6 / 19.2 / 93.75 kBd 1,200 m
187.5 kBd 1000 m
500 kBd 400 m
1.5 MBd 200 m
A maximum of 32 PROFIBUS devices can be connected in one segment. If more devices are to
be connected to a PROFIBUS line, then multiple segments have to be connected by repeaters.
The bus cable has to be installed at a distance of at least 20 cm from other cables and
should be installed in a separate, conductive and earthed cable tray.
It is important to ensure that there are no potential differences between the individual
devices on the PROFIBUS.

Connection
2
Section 2: Connection
Section 2: Connection
Depending on the order, there are the following connection options:
• Standard design: via terminal board
• Explosion-proof design: via terminals
2.1 Standard Design
PROFIBUS cables connect via the input/output board in the terminal compartment for
the customer’s plug connector for the actuator. The PROFIBUS connection is thus, like
the other electrical connections, plug- connectable both for power and signals. When
the connecting plug is unplugged, the connection within the line for the PROFIBUS
is maintained, i.e., the connecting plug can be unplugged during operation without
interrupting the communication to other bus subscribers.
NOTE
The PROFIBUS has to be terminated at the end of the line. This active bus termination can
be made on the input/output board. The supply for the terminating resistors, however, is
carried out from the actuator, i.e., with the plug connector unplugged, the bus termination
is not supplied. To avoid such problems, we recommend terminating the bus separately
with an active bus termination.
If the PROFIBUS is a single-channel design, the PROFIBUS cables connect on Channel I, and
with a dual- channel design (option: redundant), Channel I and Channel II are used.
2.1.1 Terminal Board (Provided by customer)
The terminal board is located in the terminal compartment for the customer’s plug
connector beneath the top cover.

Section 2: Connection
2.1.2 Connecting the PROFIBUS Cables
Recommended cable assembly
Before connecting the bus cable, it has to be assembled as follows:
The terminals on the terminal board are designed for a max. cross-section of up to 1.5 mm2.
The shield outside diameter has to be in the range of 5 - 8 mm.
Customer connection within the line
There are other PROFIBUS subscribers before and after the slave. Connection for the cables:

Customer connection at the end of the line, bus termination
There are no further PROFIBUS subscribers before or after the slave. Connection for the cables:
Figure 4 Single Channel
Figure 5 Dual Channel
Bus termination:
The bus has to be terminated on both ends of the PROFIBUS line. This termination can be
made via the built-in terminating resistors, which are actively supplied by the actuator. The
terminating resistors are enabled when the switch on the terminal board is switched to “ON”.

Connection 5
Section 2: Connection
2.2 Explosion-proof Design
Generally, no bus termination is provided in the BETTIS RTS in the explosion-proof design,
i.e., the bus has to be implemented on both ends on the system side.
As an option, however, the bus connection can also be implemented in BETTIS RTS. This
has to be specied when ordering.
In such case, the bus connection can be enabled by bridging the terminals:
• A to AT
• B to BT (single channel version)
• A1 to A1T
• B1 to B1T
• A2 to A2T
• B2 to B2T (dual channel version).
! WARNING
The shield has to be put on the clamping brackets (cross-section). See Figure 6 or Figure 7.

Commissioning6
Section 3: Commissioning
Section 3: Commissioning
When commissioning a PROFIBUS-DP network, the devices on the PROFIBUS-DP have to
be parameterised and congured with the project conguration software of the control
system used (PROFIBUS congurator).
In this step, each subscriber connected to the PROFIBUS also has to be given a unique address.
The project conguration software rst reads in the GSD le (General Station Description) of
the various actuators. The GSD le contains information about the device’s properties needed
by the master. The current GSD le can be downloaded at Emerson Global Sales Portal.
After that, the user can congure and parameterise each device on the PROFIBUS-DP.
This information is stored in the control system (DP master) and sent to the actuators
(DP slaves) each time communication starts up.
The following additional parameters become visible in the control unit for the Bettis RTS
actuator with the PROFIBUS option enabled.
Table 2.

Item Subitem Options Explanation/Comments
P15.1 PROFIBUS PROFIBUS
0: disabled PROFIBUS disabled
1: allow paramet. Parameterisation by the master is allowed.
(2): ignore paramet.
Parameterisation by the master is ignored.
Only parameters set in the actuator control system are
effective (recommended setting).
3: deny paramet. Parameterisation by the master is not allowed.
P15.2 PROFIBUS Address
Channel A 0 bis 125 Setting of the bus address for the rst, primary channel.
P15.3 PROFIBUS Address
Channel B 0 bis 125 Setting the bus address of the second, secondary channel (only with the option “PROFIBUS redundant”).
P15.4 PROFIBUS Watchdog
time
0.0 – 10.0 s
(0.0 s)
Monitoring of the toggle bit transmitted from the master
(bit 7 in the command). With a bus watchdog time set,
this bit has to toggle within that time; otherwise there
is a bus watchdog error. At 0.0 s the watchdog function
is disabled, in which case toggling of the toggle bit may
be omitted.
P15.5 PROFIBUS Setpoint
Source
(0): Standard The set point is specied via PROFIBUS
(only relevant when the positioner is enabled)
1: Analog The set point is specied by the analogue signal
(only relevant when the positioner is enabled).
2: Bus/Analog
With a fault-free bus, the set point is specied via the
PROFIBUS. With a bus error, the analogue value is
switched to (only relevant when the positioner is enabled).
P15.6 PROFIBUS Status 2 (0) Standard assignment for Status 2.
1 - 2 Reserved for future use.

P15.8 PROFIBUS Status 4 (0) Standard assignment for Status 4.
1-2 Reserved for future use.
NOTE
After changing an address, the control unit has to be briey switched off and back on again
in order to apply the change.

Section 4: Description of the Input
and Output Data
General information: Depending on the master, it is possible that the low byte (bit 0 - 7)
and the high byte (bit 8 - 15) might have to be swapped. The transmission mode
(big endian/little endian) always has to be adjusted such that the analogue values are
transmitted correctly. Only then can the binary data be swapped.
