Module Fault Display Cause Remedy
CAN gateway
No data transmission No LED is lit No supply voltage Make sure that the module is
supplied 24 V DC
Incorrect data transmission to
the backplane bus
LED”ER”islit No module contact with the
backplane bus.
Place module on DIN rail, turn
downward until it audibly
engages with the DIN rail.
Then restart the module by
switching the supply voltage
off and on again.
No process da ta are
transmitted
LED ’BA’ is blinking System bus in Pre-Operational
status
Transmit telegram 00 01 00
from master to change into the
Operational status.

8×digital input / output
HIGH signal at a digital input is
not transmitted/indicated.
The green status LED of the
output is not on.
High signal lacks reference
potential (GND) via pin 10.
Establish reference potential

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

Connected l oad defective Check load
Digital o utput 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 / output
Signal at analog input is not
transmitted
The red LED of the
corresponding input is li t
Open circuit within measuring
range 4 ... 20 mA

2/4×counter After a reset via the digital
input IN1 / IN4 the value 0 is
not transmitted to the master.
It is only transmitted with the
next count value.
– Process data transmission to
the master (PDO-Tx) is
event-controlled.
