Within the lines and value fields, the cursor can be moved horizontally.
A total of ten lines can be assigned. Confirm inputs by pressing
ENTER
.
The values of the operands you select are displayed in the value field in the
specified format.
If the cursor is located in the first field and if input has not been started and
updating is not in progress, you can insert a new tag line in front of the cur-
rent line using the Insert key and you can delete the current line with the De-
lete key.
If the cursor is located in a value field (not KM) containing at least one
character, use
INS
DEL
to delete the character at the cursor location.
When you have finished editing the operand list, the values on the PLC have
to be updated. This is not done immediately after an individual value has
been entered. Not until you press the Enter key again after entering the final
value is updating of all the new values explicitly initiated. During updating, a
flashing asterisk, *, is visible in the top right corner of the display. If the
asterisk does not flash, this means that the OP did not succeed in establishing
a logical link to the PLC.
Inputs cannot be made while updating is in progress. Updating can be
canceled by pressing
ESC
.
