Interrupts/diagnostic alarms
5.2 Diagnostic alarms
Cross-channel diagnostics of the digital outputs
The digital outputs of both channels have common diagnostics. As a result, when there is an
error at one digital output, errors are automatically signaled for both channels. The pulse
output of both channels is stopped in this case, regardless of whether "Enable diagnostic
interrupts" is activated.
Ensure that this fault scenario is taken into consideration when using both channels.
