The I/O-Force List - HEIDENHAIN iTNC 530 HSCI Technical Manual

9.1.5 The I/O-FORCE LIST

Add operands
to I/O -FORCE LIST
1674
With the I/O-Force List you create a table in which the status of selected
inputs and outputs is written based on the process image.
Danger
The I/O-FORCE LIST can overrule safety-relevant monitoring operations as
well as any inputs and outputs in the PLC program! Activation of the I/O-
FORCE LIST can therefore only be done with extreme care. Also make sure
that hanging axes are supported.
Meaning of the columns in I/O-FORCE LIST:
SYMBOL: Symbolic address of the operand

Absolute address of the operand

ADDR:
Content of the operand

VALUE:
 COMMENT: Comment for the operand
Press the WATCH LIST or TABLE soft key in the PLC Programming operating

mode.
With WATCH LIST: In the WATCH LIST, select the line with the desired

operand (input or output). You may also select the operand via the SYMBOL
LIST first.
With TABLE: In the TABLE, select the desired operand via soft key and the

keyboard arrow keys.
Press the ADD TO I/O-FORCE LIST soft key.

The operand is written to the I/O-FORCE LIST, and a message confirming the
transfer of the operand to the I/O-FORCE LIST appears.
Note
When using the I/O-FORCE LIST, remember that:
If an operand is entered and the I/O-FORCE LIST is activated via soft key,

then this operand is marked in color in the TABLE, and the SET and RESET
soft keys have no meaning.
The green error message I/O-Force is output in the PLC Programming

mode of operation if the I/O-FORCE LIST is active.
