3.0 Advanced Function Blocks
3.1 Integrator Block (IT)
The Integrator (IT) function block integrates one or two
variables over time. The block compares the integrated or
accumulated value to pre-trip and trip limits and generates
discrete output signals when the limits are reached.
ST_REV
: The revision level of the static data associated
with the function block.
TAG_DESC
: The user description of the intended applica-
tion of the block.
STRATEGY
: The strategy field can be used to identify
grouping of blocks.
ALERT_KEY
: The identification number of the plant unit.
This information may be used in the host for sorting
alarms.
MODE_BLK
: The actual, target, permitted, and normal
modes of the block.
• Target: The mode to “go to”
• Actual: The mode the “block is currently in”
• Permitted: Allowed modes that target may take on
• Normal: Most common mode for target
BLOCK_ERR
: The summary of active error conditions
associated with the block. The block error for the Integrator
function block is Out of service.
