Operator Panel OP3
Edition 11/99
After typing in the MPI address, you go to the operand field using the → ar-
row key. Hold down SHIFT and select the data type you wish to have dis-
played using the ↑ or ↓ arrow key. Pressing ENTER automatically sets the
corresponding data format in the format field.
Use the → key to go to the numeric field. Using the keypad, type in the num-
ber of the operand you wish to display or modify and press ENTER to con-
firm.
The cursor can be moved horizontally within the lines and value fields. A
total of 10 lines can be assigned. Confirm inputs one field at a time by
pressing ENTER. The values of the operands you select are displayed in the
value field in the specified format.
Single lines can be deleted by using the key combination SHIFT +
ESCAPE.
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 confirmed. Not until you press the ENTER key again after confirming
the final value are the new values transferred to the PLC. During updating, a
flashing asterisk * is displayed in the top right corner of the display. If the
asterisk does not flash, this means that a logical link has not been established
to the PLC. Inputs cannot be made while updating is in progress. Updating
can be canceled by pressing ESCAPE.
No inputs can be made while updating is in progress. You can abort updating
by pressing ESCAPE.
