IP 265
Entering operand identifiers in the margin bars without automatic cursor control
Proceed as follows if automatic cursor control is disabled (<ESC>) and you want to reenter or
correct an operand identifier:
Move the cursor to the input field
Activate Input mode by pressing <1>
Enter the direct or symbolic address of the operand on the programmer keyboard
Confirm your entry with <1> or <INSERT>. (Or you can revoke the entry by pressing
<ESC>).
Example: Converting identifier "I 0.1" into "I 1.1"
Initial situation
&
I 0.1
????????
Note
Before entering or converting a direct or symbolic address, you must always activate the
Input mode for the editing field by pressing <1>. In Input mode, the input field appears
as a two-line field in reverse video.
COM 265 always checks your entries. If you have entered an invalid identifier, an appropriate error
message is displayed on the "Editor" form's message line.
Input fields without identifiers ("open inputs") continue to show "???????". Open inputs in the
IP 265 user program are treated like constants with a "0" value.
Note
An operand, once entered, can be overwritten as often as required. However, it is not
possible to convert identifiers for differential inputs into those for expansion inputs or
vice versa. Examples:
• Valid conversion:
