Error message
Cause(s)
Remedy
E27
Normal operation inactive
The master signals that it is not in the
"normal operating mode".
Possible causes:
1. When booting the system no slave
was connected to the device or no
slave was projected.
► Connect at least 1 slave to the
device and reboot the system.
2. The master detects an AS-i voltage
below 22 V and therefore goes into
the "offline mode".
► Check AS-i voltage supply on the
master and replace, if necessary.
3. The master received a request from
the operating system to change to
the "offline mode".
► Check AS-i voltage supply on the
master and replace, if necessary.
4. The master found a transfer error in
the communication with the
operating system.
► Switch PLC off and on again.
► Replace controllere and project
again.
Other causes which can lead to an error
message directly after power-on:
5. Initialisation of the master after
power-on of the device was not
successful.
► Switch PLC off and on again.
► Replace controllere and project
again.
6. The master has not yet received the
projection nor the projected
parameters from the operating
system.
► Wait.
► If too long: → 5.
7. The master has not yet been started
by the operating system.
► Wait.
► If too long: → 5.
E28
State PLC cmd channel
Command channel detects an invalid
state.
► Check the request of the PLC
command channel (1
st
word).
E29
Unknown MUX field identifier
The transmission between AS-I master
and PLC processor has been deranged.
► Check data accesses via pointers
into area < 4000
h
of your PLC
program.
► Check the electrical environment
about unacceptable high electro-
magnetic fields and static charging.
► Check the grounding of the device.
E30
Safety slave triggered (1)
The first safety contact of the specified
AS-I slave is opened.
► Bring the slave into the safe state.
E31
Safety slave triggered (2)
The second safety contact of the
specified AS-I slave is opened.
► Bring the slave into the safe state.
