Boolean Fan Input function block parameters

The following table lists the system parameters for the Boolean Fan Input function block:

Table: Boolean Fan Input function block system parameters
Parameter	Units	Description
ARM_TRAP	None	When non-zero, ARM_TRAP enables the first out trap mechanism.
BCD	None	The binary coded decimal representation of the discrete inputs.
FIRST_OUT	None	A snapshot of OUT_INT when OUT_INT transitions from zero to non-zero while ARM_TRAP is non-zero.
IN_D1 to IN_D16	None	The discrete input values and statuses. The number of inputs is an extensible parameter.
OUT_D	None	The output value that represents the logical OR of the discrete inputs.
OUT_INT	None	The unsigned 32-bit binary weighted output value that represents the bit combination of the inputs.
RESET_IN	None	When non-zero, RESET_IN clears FIRST_OUT. The block sets RESET_IN back to zero at the end of each scan. RESET_IN does not re-arm the trap. FIRST_OUT remains cleared until one or more inputs are set after all inputs are zero.
