Acknowledge all errors that are present. Only then can the outputs be re-enabled.
Acknowledgment: yes (1)
Acknowledging the diagnostic message deletes the message.
The module can only be re- started or reparameterized
following power up or soft reset and error-free selftest.
Acknowledgment: yes (2)
Acknowledging the diagnostic message deletes the message
and enables a restart. Following successful acknowledgment,
the module also expects a positive edge from the application
for the output.
WARNING
Unexpected machine startup
An operator acknowledgment leads to a positive edge and can therefore result in the out-
puts being re-enabled.
