Additional Information
Refer to P3 of NI 9350 Datasheet for a circuit diagram. Each parts drawn in blue are implemented as hardware logic and each in green are as software logic.
Self Diagnostics is a hardware logic which detects faults within the module, which are situations such as:
- Short condition on both DO FETs on a single output channel
- Overvoltage on Vsup
- Internal overvoltage faults
When faults are detected, the Fail-safe Mode is triggered which de-energizes all outputs from the C Series Functional Safety module and stops the User Program.
