1 ) The parameters Behaviour DO at comm. error is only analyzed if the Failsafe-mode is ON.
2 ) The state "externally voltage detected" appears, if the output of a channel DC0...DC7 should
be switched on while an externally voltage is connected
on page 798. In this case the start up is disabled, as long as 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".
