Remarks:

)
The parameter Behavior DO at comm. error is applied to DC and DO
channels and only analyzed if the failsafe mode is ON.
2
)
The state "externally voltage detected" appears if the output of a channel
DC0..DC7 is to be switched on while an external voltage is connected.
In this case, start-up is disabled while the externally voltage is con-
nected. The monitoring of this state and the resulting diagnosis message
can be disabled by setting the parameters to "OFF".
3
)
The error state "voltage overflow at outputs" appears if external voltage
at digital outputs DC0..DC7 and DO0..DO7 has exceeded the process
supply voltage UP3 (see 'Connections' Ä Chapter 1.7.2.3.3 “Connec-
tions” on page 660). The according diagnosis message "Voltage over-
flow on outputs " can be disabled by setting the parameters to "OFF".
This parameter should only be disabled in exceptional cases as voltage
overflow may produce reverse voltage.
