The following table lists the system parameters for the Multiplexer function block:
Table: Multiplexer function block system parameters
Parameter
Units
Description
ABNORM_ACTIVE
None
The indication that a block error condition not selected in BAD_MASK (on the function block level) is True (Active) or the indication that an error condition (at the module level) not selected in MERROR_MASK is True (Active) or a module status not selected in MSTATUS_MASK is True (Active).
BAD_ACTIVE
None
The indication that a block error condition selected in BAD_MASK (at the function block level) is True (Active) or the indication that an error condition (at the module level) selected in MERROR_MASK is True (Active) or a module status selected in MSTATUS_MASK is True (Active).
BAD_MASK
None
The set of active error conditions that triggers a user-defined Bad condition. The user selects a subset of block error (BLOCK_ERR) conditions in the BAD_MASK parameter. When any of these conditions are True, the BAD_ACTIVE parameter becomes True. When any of the BLOCK_ERR conditions that are not included in BAD_MASK are True, ABNORM_ACTIVE becomes True.
BAL_TIME
Seconds
Specifies the time for the old input value to ramp to the newly selected input value.
BLOCK_ERR
None
The summary of active error conditions associated with the block. The possible block errors are:
Input Failure/Bad PV
IN1 to IN16
Determined by source
The analog input values and statuses. The number of inputs is an extensible parameter.
OUT
Determined by source
The analog output value and status.
SELECT_NEXT_GOOD
None
Selects the next input with Good status when the selected input has Bad status (True [1] = enabled, False [0] = disabled).
SELECTOR
None
Selects the input to place at the output.
