OMRON
Some objects (excluding the rung and text comments, and the vertical and horizontals) have associated dialogs
allowing address or instruction information to be entered. Double-click on the object to redisplay the Edit
dialog, this is dependent upon the selection.
The Auto Error Detection bar to the left of the rung indicates the validity of the entries.
It is possible to design a network and get the geometry right before entering specific symbol or address
information.
Program steps (graphically represented) are entered in a row or ladder 'rung' between the left (power supply)
and right (output) bus-bars.
Additional rows and columns can be inserted into the Ladder program via the Insert Row option and Insert
Column option from the context sensitive menu. Rows and columns can also be removed by selecting Delete
Row option and Delete Column option from the context sensitive menu.
By inserting Vertical Up or Vertical Down, rungs cannot be combined into one. To do this, select the rungs to be
combined and select Combine from the context sensitive menu. When a rung needs to be divided, select Split
from the context sensitive menu to divide the rung into two.
Allowing ladder screen display only, and prohibiting program editing while offline is possible (CX-Programmer
Ver. 4.0 or later). Select Read Only Mode from the Edit Menu to enable this function.
After temporary editing of a specific rung (in temporary memory), the user can select to utilize (store) or delete
(cancel) the editing results (CX-Programmer Ver. 4.0 or later). Select Read Only Mode – Start Edit from the
Edit Menu, and then perform either of the following steps after editing.
a) To apply the editing results, select Read Only Mode – Store from the Edit Menu. The edited contents will
be reflected in the program.
b) To not apply the editing results, select Read Only Mode – Cancel from the Edit Menu. The edited contents
will be deleted. Therefore, after editing rungs and writing and recording temporary changes, the user can
select to either apply or delete changes, enhancing program editing efficiency. (This function is similar to
the SYSMAC Support Software store function.)
