Segment Display
Figure 43. Segment Display
The power rails are displayed in red because they are always powered. The rungs
and branches are displayed in red if they have power, or in white if they do not. The
elements are labeled with the name that was entered for them when the segment was
built. Examine On Symbols shows either the state of the contact or the data quality
of the input. Timers and counters show either their enable/disable condition or
whether they are still running. Remarks are displayed on their own rung. A closed
segment also closes its data access subscription (does not collect data in background
when closed).
File instructions,
files, files to registers, and from one file to another. Each instruction has a counter
associated with it to provide an index into a file for a particular element (counter
faceplates must be accessed from the counter display). The counters are
incremented or decremented by the Ladder Logic to provide the proper index for the
Register to File Move and File to Register Move Instructions. The entire contents of
a file is moved by the File to File Move Instruction. Not done is indicated by ND on
the File to File symbol.
