<strong>Digital</strong> <strong>Exception</strong> <strong>Report</strong>Function Code <strong>45</strong>S1 (<strong>45</strong>)DO/LNThe digital exception report function code exception reports. Specification S2 defines the alarm state.<strong>Exception</strong> reports are activated by a report enable signal fromthe module bus. The maximum number of exception reportsallowed depends on the controller configuration. The numberof exception reports is defined in the executive block of thecontroller.Use function code 69 to test the alarm associated with theanalog input/loop function block.OutputsBlk Type DescriptionN B Value of exception reportSpecificationsSpec Tune Default Type Range DescriptionS1 N 0 I Note 1 Block address of inputS2 N 2 I 0 - 2 Alarm state:0 = logic 0 alarm state1 = logic 1 alarm state2 = no alarm state definedNOTES:1. Maximum values are: 9,998 for the BRC-100, IMMFP11/1231,998 for the HACExplanation<strong>Exception</strong> <strong>Report</strong>sAn exception report returns to the module bus following areport poll message if a report enable message has beenreceived for the block number. To import this data to anotherPCU, this requires programming a digital input/loop block(function code 42) or digital input/Cnet (function code 122) inanother node referencing the output of the function code <strong>45</strong>block. To import this data to a console the point must beadded to the tag list.WBPEEUI210504B0 <strong>45</strong> - 1
An exception report occurs when:1. = L and tr > tminwhere:or2. tr > tmaxwhere: = Current value of input. L = Last reported value of input.t r = Time since last report.t min = Minimum report time for the block as specifiedby the executive block or the segmentcontrol block.t rt max= Time since last report.= Maximum report time for the block as specifiedby the executive block or the segment controlblock.An alarm report returns to the bus interface module followinga report poll message if a report enable message has beenreceived for the block number.An alarm report occurs when:3.
