Tag Analog Output (TAGAO) function block parameters

The following table lists the parameters for the function block.

Table: Tag Analog Output function block system parameters
Parameter	Units	Description
ABNORM_ACTIVE	None	Can indicate one of the following: A block error condition not selected in BAD_MASK (at the function block level) is True (Active). An error condition (at the module level) not selected in MERROR_MASK is True (Active). A module status not selected in MSTATUS_MASK is True (Active).
BAD_ACTIVE	None	Can indicate one of the following: A block error condition selected in BAD_MASK (at the function block level) is True (Active). An error condition (at the module level) selected in MERROR_MASK is True (Active). 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.
BLOCK_ERR	None	Can indicate that the block has a bad input through the Input Failure/Bad PV error.
EUMAX	EU of PLC control tag	The configured high scale of PLC control tag engineering units (Cfg_CVEUMax).
EUMIN	EU of PLC control tag	The configured low scale of PLC control tag engineering units (Cfg_CVEUMin).
EUSTR	EU of PLC control tag	The configured units type string of PLC control tag engineering units (Cfg_EU).
OUT	EU of PV_SCALE	The analog output value and status from the final output value after limiting of the PLC control tag (Val_CVOut).
OUT_CV	EU of PV_SCALE	The raw analog output value and status from the PLC control tag (Out_CV).
PV_SCALE	EU (default=None)	The mirrored high and low scale of the PLC control tag EU scale. Only the decimal point is tunable (this is used in default displays). The system does not user 100% of scale and 0% of scale values or the Engineering unit values configured in the PV_SCALE Properties dialog. Instead, the system populates scOUT_SCALEale values at runtime using values from the PLC tag. The Engineering unit field is empty at runtime, the EUSTR parameter displays the engineering units configured in the PLC tag.
SP_HILIM	EU of PLC control tag scale	The configured high setpoint limit in the PLC control tag (Cfg_MaxCV).
SP_LOLIM	EU of PLC control tag scale	The configured low setpoint limit in the PLC control tag (Cfg_MinCV).
STATUS	None	The status reported from the PLC control tag (SrcQ).
