Fieldbus Multiple Discrete Input function block parameters

The following table lists the system parameters for the Fieldbus Multiple Discrete Input function block.

Table: Fieldbus Multiple Discrete Input function block system parameters
Parameter	Units	Description
ABNORM_ACTIVE	None	The indication that a block error condition not selected in BAD_MASK is True (Active).
ALERT_KEY	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 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 Fieldbus Multiple Discrete Input function block are: Out of Service Input Failure/Bad PV Simulate Active Other Error
CHANNEL	None	The number of the logical hardware channel that is connected to the I/O block. It defines the transducer to be used going to or from the physical world.
MODE	None	The mode record of the block. Contains the actual, target, permitted, and normal modes.
OUT_Dn where n=1 through 8	None	The discrete output value and status.
ST_REV	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	None	Used to identify groupings of blocks. This data is not checked or processed by the block.
SUBSTITUTE_IN_D	None	The substituted (from a field device) discrete input value and status. This parameter is used to provide user-entered value and status to OUT_Dn when either the device placeholder is not commissioned or the device is not communicating with the H1 card.
