This buscoupler allows connection of the of the BRIOS2
I/O-system WAGO ➟I/O➟SYSTEM as a slave to as the a slave PROFIBUS to the PROFIBUS fieldbus. fieldbus.
The buscoupler is capable of supporting all bus modules.
The buscoupler automatically configures, creating a local
process image which may include analog, digital or specialty
modules. Analog and specialty module data is sent
via words and/or bytes, digital data is sent bit by bit.
PROFIBUS allows the storing of the process image in the
corresponding Master control (PLC, PC or NC).
The local process image is divided into two data zones
containing the data received and the data to be sent.
The process data can be sent via the PROFIBUS fieldbus
to the PLC, PC or NC for further processing, and received
from the field via PROFIBUS.
The data of the analog modules is stored in the process
image which is created automatically according to the
order in which the modules are connected to the buscoupler.
The bits of the digital modules are sent byte by byte
and added to the analog data. If the amount of digital
information exceeds 8 bits, the buscoupler automatically
starts with a new byte.
When implementing new installations with
PROFIBUS DP, please consider fieldbus coupler
750-333 with extended functions (page 1.016).

The desired node address is set by
means of the two encoding switches
located on the buscoupler. The address
is adjustable in the range of 0

switching on the buscoupler. Changing
the address switches during operation
does not affect the buscoupler
address since it is read only during
the power up sequence.

The fieldbus LEDs show the operating condition of the fieldbus. The functions of PROFIBUS are
indicated by the LEDs “RUN”, “BF”, and “DIA”. The fourth LED available has no significance.

1. Coupler has left initialization and is ready for
parameterization and configuration.
2. Error in parameterization and/or configuration.
3. Wrong station address.
4. Break in the connection to the master (short
circuit, wire break)
RUN:
Inputs are read, outputs are written.
CLEAR:
Inputs are read and outputs set.

4 Buscoupler startup and troubleshooting
After configuration of the master connection and electrical installation of the fieldbus
node/station, operation of the system can begin.
After power to the Buscoupler and I/O modules has been applied, the Buscoupler verifies
all internal functions, components and the communication interface by an internal diagnostic
routine. Then the function modules and the existing configuration is determined.
During the power up phase the ‘I/O ERR’ LED flashes with a high frequency. After a
faultless power up the buscoupler enters the state ‘fieldbus start’. The green LED ‘RUN’
indicates that the internal bus is operating normally.

In case of a fault, the red ‘I/O ERR’ LED will continue flashing.
By counting the number and frequency of flashes the fault can be easily identified quickly and accurately. A varying
number of flashes and frequencies defines the fault. The table below describes the fault condition based on the
counted number of ‘I/O ERR’ LED flashes.

Blink code example:
* The number of blink pulses (n) indicates the position of the I/O module.
I/O modules without data are not counted (i.e. supply module without diagnostics).
Assume that the 13th I/O module is removed. This will generate the following cyclically displayed blink sequence:
1. The ‘I/O’ LED generates a fault display with the first blink sequence (red, approx. 10 Hz) and then pause.
2. The first pause is followed by the second blink sequence (approx. 1 Hz). The ‘I/O’ LED blinks red four times
and then pause. This indicates the error code 4 meaning an Internal bus data error.
3. The second pause is followed by the third blink sequence (approx. 1 Hz). The ‘I/O’ LED blinks red twelve
times and then pause. The error argument 12 means that the internal bus is interrupted after the 12th I/O
module.
After elimination of the fault, the buscoupler can only be set to the normal working condition by another POWER ON
sequence.
The green I/O RUN LED flashes when accessing the I/O modules internal data channels. After being switched on, the
Buscoupler queries the configuration of the bus modules but does not carry out a data exchange with the I/O modules.
This means that the red I/O ERR LED will extinguish after a faultless startup. The green I/O RUN LED indicates that
data is being exchanged via the internal bus.
