CAN gateway

No data transfer

No LED is lit.

No supply voltage.

Make sure that the module is
supplied with 24 V DC.

Incorrect data transmission to
the backplane bus.

LED "ER" is lit.

No module contact with the
backplane bus.

Place module on DIN rail, turn
downward until it audibly
engages with the DIN rail.
Next, restart the module by
disconnecting and
reconnecting the supply
voltage.

No process data is transmitted. LED ’BA’ is blinking.

System bus in
"Pre−Operational" state.

Transmit telegram 00 01 00
from master to change into the
"Operational" state.

Parameter changes were not
saved after supply voltage
disconnection.

Parameter changes were not
saved.

8×digital input
16×digital input
1×counter/16×digital input
8×digital input / output

HIGH signal at a digital input is
not transmitted/indicated.

The green status LED of the
output is not lit.

High signal lacks reference
potential (GND) via pin 10.

Establish reference potential.

8×digital output 0.5A
16×digital output 0.5A
8×digital output 1A
16×digital output 1A
8×digital output 2A
8×digital input / output

No HIGH level output at the
digital output.

The red status LED ’F’ is lit.

Short circuit at a digital output
due to incorrect wiring.
The output remains off until the
error has been eliminated.

Check wiring.

Connected load defective.

Check load.

Digital output overload as
load’s current consumption is
too high.

Select load with lower current
consumption.
When using the module
8×digital output 1A, exchange
it, if possible, by a module
8×digital output 2A.

4×relay

Relay contact does not open.

Excess load has lead to relay
contact fusing.

Replace module and reduce
load on the relay contact.

4×analog input
4×analog input ±10V
4×analog input ±20mA
4×analog input / output

Signal at analog input is not
transmitted.

The red LED of the
corresponding input is lit.

Open circuit within measuring
range 4 ... 20 mA.

Check wiring.

No sensor connected.

Connect sensor.
Short−circuit the plus and
minus terminals of an input if it
is not to be used.

The red LED of the associated
input is blinking.

Input current >40 mA.

Reduce input current.

2/4×counter

If networking takes place via
system bus (CAN) or CANopen,
the value 0 is not transmitted
to the master via the digital
input IN1 / IN4 after a reset.
The transmission only starts at
the next count value.

Process data transfer to the
master (PDO−Tx) is
event−controlled.

Setting cyclic process data
change (I1800
