Will all points connected in Triconex DI-3503E module go to FALSE indications if any of its input points fail the Stuck On test?
Stuck On Test of Triconex DI-3503E

I'm no expert on Triconix but having used fault tolerant PLC's - and Using the linked Analysis as a guide:

It appears failure of a 'stuck on test' will not affect any other points on the module, and upon genuine failure will most likely only be single point failure where only one of the three 'legs' will be diagnosed, and outvoted by the other 2 legs.
