Error caused by
receiving an
unexpected message
for the
acknowledgement of
diagnostic messages.
The allocation of the diagnostic and activation
variables on the acknowledgement module should
be checked.
The device firmware handles this diagnostic
message with the highest priority. It is not until this
is correctly acknowledged that other errors, if
present, are notified.
Error caused by
receiving an
unexpected value
regarding the process
data image. All outputs
are switched off
immediately.
At least one reserved bit in the process data image
was set. The process data allocation should be
checked.
The acknowledgement deletes the message and
releases all outputs.
The time between two
restarts of the outputs
is too short – the time
interval must be at
least 30 seconds.
By acknowledging one of the following diagnostic
messages 0x021X, 0x025X, 0x026X, 0x028X,
0x029X, 0x02AX or 0x02EX, provided there are no
other relevant error messages, a restart of the
outputs can be triggered. The repetition of this
process is only possible after a waiting time.
Only applies to Safety
Mode (Module
Passivation/xxx)
The SI unit received
an invalid process
image for the
parameter values.
The process image for parameter values must
contain valid values.
The SI unit needs a HW reset when the process
image contains new parameter values.
Hardware reset can be performed by downloading
a project to the PLC using the configuration
software and resetting the power supply of the SI
unit.
The start-up mode
(CM) was activated.
The acknowledgement deletes the message.
