Signal Characterizer function block parameters

The following table lists the system parameters for the Signal Characterizer function block:

Table: Signal Characterizer 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).
ALERT_KEY⁽¹⁾	None	A user-assigned identification number reported in alarm messages from the block that allows HMI applications to sort and filter alarms and events. Set this parameter for each function block to indicate the physical unit the function block is associated with. This information can be used in the host for sorting alarms, and so on.
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.
BLOCK_ERR	None	The summary of active error conditions associated with the block. The possible block errors for the Signal Characterizer function block are: Out of Service Configuration Error
BYPASS	None	When BYPASS is enabled in the Signal Characterizer function block, it bypasses the signal characterization. OUT_1 equals IN_1 and OUT_2 equals IN_2. To enable BYPASS, set the BYPASS parameter to On and select the CONTROL_OPTS Bypass Enable option.
CONTROL_OPTS	None	Control options allow you to specify control strategy options. The supported control option for the Signal Characterizer function block is: Bypass Enable.
CURVE_X	Determined by source	The array of input curve values (as many as 21 points).
CURVE_Y	Determined by source	The array of output curve values (as many as 21 points).
IN_1	Determined by source	The first analog input value and status.
IN_2	Determined by source	The second analog input value and status.
MODE	None	The mode record of the block. Contains the actual, target, permitted, and normal modes.
OUT_1	EU of IN	The analog output value and status related to IN_1.
OUT_2	EU of IN	The analog output value and status related to IN_2.
ST_REV⁽¹⁾	None	The revision level of the static data associated with the function block. To support tracking changes in static parameter fields, the associated block's static revision parameter is incremented each time a static parameter field value is changed. Also, the associated block's static revision parameter is incremented if a static parameter field is written but the value is not changed.
STRATEGY⁽¹⁾	None	Used to identify groupings of blocks. This data is not checked or processed by the block.
SWAP_2	None	Swaps the X and Y axes used for OUT_2.

⁽¹⁾ These parameters are only visible when the function block is extended to a fieldbus device.

Note

Default values and data type information for the parameters are available by expanding the Parameter View window.
