1 Overview
The SIMATICr505 PROFIBUS-DP Remote Base Controller (RBC),
PPX:505–6870, allows a Series 505tI/O base to function as a slave node on
a DP I/O channel that complies with the PROFIBUS standard (DIN 19245,
Part 3). The SIMATIC 500 PROFIBUS-DP Remote Base Controller (RBC),
PPX:500–6870, allows a Series 500tI/O base to function as a slave node on
a DP I/O channel that complies with the PROFIBUS standard.
The 505 and 500 PROFIBUS-DP RBCs offer the following features:
•The RBC is compatible with Siemens S5tand S7t, as well as Series
505, masters.
•The 505 RBC can be used in all currently-available Series 505 bases
(4-, 8-, 11-, and 16-slot models).
•The 500 RBC can be used in all Series 500 bases (6-, 12-, and 14-slot
models, or original 8- and 16-slot models with PPX:500–5840 adapter).
•The RBC supports communication speeds from 9.6 Kbaud (maximum
cable distance per segment: 1200 m) up to 12 Mbaud (maximum cable
distance per segment: 100 m).
•The LED display shows error codes or current station address.
•A serial port is available for remote programming of the CPU when the
RBC is used on a Series 505/500 system.
•The RBC has a field-upgradeable operating system that is stored in
flash memory.
•The base where the RBC resides can contain only modules that look
like discrete or analog I/O; Special Function modules like Peerlink or
NIMs are not supported.
•CPU commands received from the serial port are restricted to those
that cannot alter the PROFIBUS-DP I/O configuration.
•A “GSD” file is provided with the RBC to allow configuration by the
COM PROFIBUS configuration utility.
Figure 1 illustrates how the 505 and 500 PROFIBUS-DP RBCs fit into the
I/O architecture of a Series 505 system.

3 RBC Ports
The 505 and 500 PROFIBUS-DP RBCs have two communication ports, an
RS-232 port and a PROFIBUS-DP I/O channel port.
When used with a Series 505 CPU, the RS-232 port is an interface to
programming devices that use software like TISOFT or other configuration
tools. To connect your RBC to a programming device/modem, use a standard
9-pin RS-232 serial cable that conforms at a minimum to the pinouts shown
in Figure 4. A standard cable that conforms to the minimum requirements
is available through Siemens; specify part number 2601094–8001.

SIMATIC 505/500 PROFIBUS-DP RBC User Manual
The PROFIBUS-DP port is used to connect the RBC to the PROFIBUS-DP
I/O channel. The SIMATIC 545/555/575 System Manual describes how to
connect a 12 Mbaud RS-485 cable to the PROFIBUS-DP port. Figure 6
shows the pinout for the PROFIBUS-DP port for the PROFIBUS-DP RBC.
NOTE: Pins 2 and 7 are “No Connect” for the RBC. For some PROFIBUS
products, these pins are used to provide 24 VDC for powering a
programming or configuration tool. Such tools are not powered by the RBC;
however, it is acceptable for an externally-powered PROFIBUS
programming or configuration tool to drive pins 2 and 7 to 24 VDC.

!CAUTION
Pin 5 (BIAS SUPPLY +5V) and Pin 6 (BIAS SUPPLY GND) on the PROFIBUS-DP
connector are designed to support the PROFIBUS-DP I/O channel only. These
pins have a limited output power capability of approximately 0.45 W, which
greatly exceeds the typical PROFIBUS-DP load; however, overloading these
pins may cause internal component damage.
If the pins are overloaded, the PROFIBUS-DP port can be rendered
non-functional, requiring the unit to be returned to the factory for repair.
Do not overload the pins on the PROFIBUS-DP connector.

4 Output State Selection on the RBC
When I/O channel communication to a Series 505 base is lost, the state of
the outputs is determined by the selection made on the 505 RBC jumper E1
(Off/Freeze). Figure 7 shows the location of the jumpers on the 505 RBC.
NOTE: You must make an E1 jumper selection on the 505 RBC. The RBC
Status Display reports an error if no jumper selection is made.
The jumpers on the 505 RBC headers E2 and E3 are for factory use only.
Header E4 is shipped without a jumper. Do not alter the default settings
unless instructed to do so by a Siemens Technical Support technician.

Output State Selection on the RBC (continued)
For discrete output modules, the state of the outputs is determined solely by
the position of the Off/Freeze jumper E1 on the 505 RBC or the Off/Freeze
switch on the 500 RBC.
For analog/word output modules, the state of the outputs is influenced not
only by the position of the Off/Freeze switch but by the output module’s
(Zero/Hold Last Value) selection, if the module has that option. See Table 1.
Table 1 Analog/Word Output States
RBC Off/Freeze Selection Analog/Word Module
Zero/Hold Selection Analog/Word Output State
Off Zero Zero*
Off Hold Last Value Last Value
Off – no selection – Last Value
Freeze Zero Last Value
Freeze Hold Last Value Last Value
Freeze – no selection – Last Value
*See the user manual of your analog/word output module for further details.
Notice, in Table 1, that the Freeze option on the RBC overrides the Zero
selection on the analog/word output module; likewise, when Hold Last Value
is selected on the analog/word output module, that selection overrides the
Off option on the RBC jumper.
NOTE: If the RBC hardware watchdog timer is activated (by an RBC
failure), the state of the outputs is determined by the output module, with
no reference to the RBC’s Off/Freeze setting. Discrete outputs go off (to a
value of zero). Analog/word outputs obey their own Zero/Hold Last Value
selection. If no Zero/Hold Last Value selection is available on the module,
the analog/word outputs hold their last value.

Switches 1 through 3 on the dipswitch control the baud rate of the
RS-232/423 port. Table 2 lists the baud rates available.
Invalid selections cause the RBC to report an error on the Status Display
and cause the RS-232/423 port to default to 9600 baud.
The RS-232/423 baud rate switch settings are read only on power-up or
after pressing the reset button.
NOTE: The RS-232 port is disabled by default. To enable the port, change
the default parameter of the module in COM PROFIBUS. (See Table 5.)

Switches 4 through 10 on the dipswitch are used to assign a station address
to the RBC for identification in the PROFIBUS-DP I/O channel. Each
station in the PROFIBUS-DP I/O channel must be uniquely numbered. The
station address is assigned as a binary number, with SW10 as the Least
Significant Bit (LSB). Table 3 shows how to set the dipswitch to a station
address between 0 and 125 (the valid range of station addresses).
The station address switch settings are read only on power-up or after
pressing the reset button.
!WARNING
Pressing the RESET button when the system is operating causes the RBC to be
logged off the system and may change the output states of the output modules
in the base. Inadvertently logging the RBC off the system or changing output
states can cause unpredictable process operation.
Unpredictable process operation can result in death or serious injury to
personnel, and/or damage to equipment.
Do not push the reset button unless you intend to log the RBC off the system.

NOTE: It is possible to select Station Addresses 126 or 127 on the dipswitch, but these addresses are invalid.

16 SIMATIC 505/500 PROFIBUS-DP RBC User Manual
Dipswitch Options (continued)
The RESET pushbutton on the front of the RBC is deliberately recessed to
prevent accidental activation. When you press this button, a global reset is
immediately performed on the RBC. After completing reset, the RBC
assumes the RS-232 baud rate stipulated by the setting of switches 1
through 3 on the dipswitch, and the station address indicated by switches 4
through 10.
!WARNING
Pressing the RESET button when the system is operating causes the RBC to be
logged off the system. When the RBC is logged off, inputs and outputs
associated with the base are affected. See the documentation for your system
master to find out how the master handles I/O when the RBC logs off. If you do
not take the condition of your inputs and outputs into account, logging the RBC
off the system can cause unpredictable process operation.
Unpredictable process operation can cause death or serious injury to
personnel, and/or damage to equipment.
Do not reset your RBC unless you understand and are prepared for the
consequences.
The following actions take place when an RBC is reset.
•The CPU logs the RBC off the system and sets the image register
points which represent the inputs from this RBC’s base to zero. The
image register is zeroed out until the RBC completes reset and resumes
communication with the CPU. If this occurs while the system is
operating, depending on your RLL program, turning these inputs off
could affect other base outputs.
•From the assertion of reset until the RBC completes the reset and
resumes communication with the CPU, the state of the outputs on this
RBC’s base is determined by the output module, with no reference to
the RBC’s Off/Freeze setting. Discrete outputs go off (to a value of zero).
Analog/word outputs obey their own Zero/Hold Last Value selection. If
no Zero/Hold Last Value selection is available on the module, the
analog/word outputs hold their last value.
•If the station address you assign to the RBC (by setting the dipswitch)
inadvertently duplicates an address already in use by another slave on
the I/O channel, then when the RBC completes its reset and attempts
to communicate, identifying itself with the new station address, the
other slave may be logged off the system. Intermittent operation could
occur as long as the two slaves are set to the same station address.
