Functional Units of the Controller Board
DIP Switches
The DIP switches for setting the board address
and the startup operating mode for the slave
device are on the upper edge of the board and
are positioned so that they can be set when the
board has been inserted.

Because the slave and master core can be supplied with voltage independently from each
other, it is possible that the slave part may be ready to operate before the master. As a
result, a "NOT READY" ID is provided in the SВµPI3, which indicates to the higher-level
master that the IBS device has a SВµPI3, operating in ВµP mode, which has not yet been
initialized. After startup, the SВµPI3 has this special ID code (38hex) and 0 words in the
INTERBUS ring and the ring can therefore be started up.
To achieve compatibility with a higher-level Generation 3 bus master, the startup behavior
of the SВµPI3 can be modified using DIP switches 1 and 2. This step must be carried out
because Firmware 3.X does not support the "Not Ready" ID code.
The board address can be set to any value
divisible by 8 in the range between 100hex and
3F8hex using DIP switches 4 to 10. Eight
consecutive addresses in the I/O channel are
used.

I/O address
DIP switch 3 (test mode) is not used for setting
addresses. It is used to activate the test mode.
When the controller board is restarted with test
mode switched on, it starts the INTERBUS
system with automatic addressing, and
initializes it. During test mode the controller
board does not respond to instructions from the
host system (PC). Any parameterization stored
on the controller board is not read in. The
controller board initializes and starts up the
4
Default
INTERBUS system independently. Outputs are
not set.
The test mode is not intended for normal
operation of the controller board. To deactivate
test mode, set switch 3 to OFF.

Diagnostic Interface (Optional)
The serial diagnostic interface on the controller board has been designed as a 10-pos. DIL male
connector. A flat-ribbon cable is inserted into this male connector so that it can be converted into a
standard 9-pos. D-SUB male connector. The D-SUB male connector can be inserted either in an
additional mounting cover or in a free mounting slot on the housing.

Bus Connection Using Optical Fibers
The optical fiber cables of the remote bus must be fitted with the appropriate F-SMA connectors. HCS
fiber cables and polymer fiber cables can be used as optical fiber cables (see Table 4).
Plug the connectors into the sockets provided and secure the connections with the cap nuts. "Remote
In 2" indicates the connection for the incoming remote bus, while "Remote Out 2" indicates the
connection for the outgoing remote bus of the slave interface.
"Remote Out 1" indicates the master interface. The terms "Trans." and "Rec." indicate which
connector receives (Rec.) or transmits (Trans.) data.

INTERBUS Slave
Up to 10 data words are available when the
SВµPI3 protocol chip is used with a serial register
expansion.
The external supply of the slave interface with a
24 V voltage can be provided to ensure that the
slave is ready to operate even if the host PC is
disconnected. The slave interface is
automatically supplied with voltage when the PC
is switched on and thus an external supply is not
required. The external supply is electrically
isolated from the PC voltage using a DC/DC
converter.
No measures for the filtering of high-frequency interference voltage are provided so please
ensure that only undisturbed voltages are fed to the PC or a filter (IBS ISA SC/RI-LK FIL,
Order No. 27 22 72 6) is placed directly in the housing slot.
EMC Filter for External Voltage Supply (Optional)
The filter is used to feed a 24 V current supply
from the industrial sector with ambient class 4
(harsh industrial environment) into a device,
typically a PC, which requires ambient class 1
(well protected environment). It is designed for a
current of up to 1 A and contains protection
against polarity reversal. The external
connection is made using a 3-pos.
POWER-SUBCON connector. The filter is
installed in a slot inside the housing, which is
normally used for installing 9-pos. D-SUB
connectors. The housing is connected using the
usual printed circuit board connections for flatribbon cable with connectors attached. The
threaded joints of the POWER-SUBCON
connector make a good conductive connection
to the grounded housing (if the inside of the
housing is not coated).

Multi-Port Memory (MPM)
The 64-kbyte MPM has been designed as a
static RAM (SRAM) and exchanges data
between the host PC and the controller board.
The MPM is displayed in the address area of the
host (between 640 kbytes and 1 Mbyte). The
space available is limited and therefore only
memory windows with 4-kbytes are used. The
device driver shifts the window automatically to
the required address area of the MPM. During
shifting, the window address in the memory area
of the host remains constant.
The window address can be set by the software
to any address divisible by 4096 ranging from
80000hex to FF000hex. After the PC has been
reset the window is switched off. The window
must be enabled by the driver software.

MPM structure
An integrated watchdog timer on the controller
board can be used to monitor the running of the
application program on the PC. The watchdog
timer is switched off after a system reset and
must be enabled by the driver software.
The watchdog timer is triggered by write or read
access to an I/O register of the board. If the
monitoring time is exceeded, the watchdog timer
forces a bus reset and resets all INTERBUS
module outputs via the INTERBUS master.
The MPM includes (see Figure 7):
–
The Mailbox Interface for exchanging
commands and messages (message area)
–
The Data Interface for exchanging process
data (process data area)
–
Register for exchanging status and
handshake information
–
The Signal Interface for executing
predefined commands (command area).
Write and read access to the MPM can be
gained using the corresponding drivers.
Application programs can access input and
output process data to execute logical
operations. Command and message buffers are
used for sending and receiving commands from
the controller board and PCP commands. When
the application program is running, mainly
process data is transmitted. The application
program reads the input process data, carries
out logical operations, and then writes in the
5312A

Programming
Individual applications are created with the
support of the corresponding drivers. These
drivers are available for commonly used
operating systems and programming languages.
The drivers execute write and read operations
on the MPM and the I/O addresses.
