In all cases, the accessed network places the cursor in the home position
(row 1, column 1) and displays the new power flow information.
6.3.4.9 SRCH-SHIFT/CONTINUE SRCH
The SEARCH function enables a search through the logic networks for the
occurrence of a specific reference number or node type. There are four
types of search which are designated by parameters 1 to 4 as follows:
SEARCH TYPE
SEARCH DESCRIPTION
1
2
Search for a coil with a given reference number.
Search for a single node with a specified
reference number.
3
Search for a double node which employs a
register with a specified reference number. This
includes implied references associated with
adders and subtractors.
4 Search for a given node type. This search looks
only for the basic node type regardless of the
existence of verticals or latches.
To use the SEARCH function, enter the desired search type into the DATA
field and press the SRCH key. Next, enter the appropriate reference
number or node and press the SRCH key a second time.
For example, to search for coil 0007; press the following keys:
1
0007
The search is started from Network 1, Column 1, Row 1 of the user logic
and proceeds from Row 1 to Row 4 of each column and from column 1 to
column 7 of each network through all the networks until the first
occurrence of the reference or node is found. The search stops in EXAMINE
mode with the cursor on the node which has just been found.
Further occurrences of the specified reference or node can be looked for
by pressing the SHIFT key and then the SRCH key. This continues the
search. The Continue function is available only as the next step after a
successful Search or Continue function. The only keys which can be
pressed and preserve the Continue option are SHIFT, SEARCH, NET, and
the CURSOR movement keys. A Continue function proceeds from the last
found occurrence of the conditions, even if the cursor has been moved or
the network number has been changed. A successful Continue operation
leaves the panel in the EXAMINE mode with the cursor at the discovered
node and the SHIFT ON.
If a Search or Search Continue operation proceeds to the end of the user
logic without finding an occurrence of the specified conditions, error code
79 is displayed and the cursor is returned to its position immediately prior
to starting the current Search or Continue operation. The SHIFT state is
removed, if present.
6.3.4.10 ENTER
The ENTER key allows the user to enter initial information or change
existing information associated with the node at the cursor’s current
