condition.
Pt00OutputShortCircuit – The Pt00OutputShortCircuit bit will
indicate if the output point 0 has a short condition. A value of 0 indicates
no fault; a value of 1 indicates a fault condition; output short-circuit
detection only occurs when the output is ON. Short circuit detection can
be enabled or disabled during configuration.
