MOD 30ML Functions
DISPLAY BLOCK
When a remote input is 'edited' or written to by a script statement, the remote variable itself
will be changed (as in a supervisory message). In this way the input is really an output. The
output variable should not be tested immediately by the script after writing to it because the
message will need time to process.
2.2.2 Display Block Parameters
The mnemonics, valid values, and data types for all fields that may be selected for display
and/or be used in making softwiring connections are listed in Table 2-1. A description of each
attribute is provided in the attribute list that follows the table.

Block Type
DISP
This is the display block type.
00
Block Version (VERSION) ................................................................................................ – – R
The display block is at version 1.
01
Block Length (BLKLEN) .................................................................................................... – – R
Number of database bytes taken by the block. Always an even number.
02
State (STATE) .................................................................................................................... – – R
See IB-23G600 (Logic Book 1) Section 2.4.1, State Changes for additional information on
block states.
RUN 0 Normal Operation. Block is always executed.
03
Bad Inputs (BADINP)......................................................................................................... CWR
See IB-23G600 (Logic Book 1) Section 2.3.2, Data Quality for additional information.
Rejected 0 Block checks data quality on its inputs and if a displayed input is bad, it
will be indicated on the display. If the input is displayed on a 'line', an
error message will alternate with the value. If on a bar or bar segment,
the bar or bar segment will flash.
Accepted 1 Block runs its algorithm without a check on input quality.
