8.3.3.11 PLC Statement List
The device contains an internal PLC function for an optimum
adaptation to the respective purpose. The PLC has access to all
digital data without requiring an external wiring. Control tasks of
the external unit can be taken over if a certain extent is not
exceeded.
Overview of the PLC statement list:
- Line number
- Commands
- Operand
- Parameter
- State
1
- Comment
1)
(for digital signals) the actual digital condition of the operands (0 = inactive, 1 = active) or
(for Byte and Word commands) the hexadecimal value or
(for time constants of timers) the elapsed time in seconds.
The marked line is changed by operating the “ Edit ” button.
A new line is inserted under the marked line (quitting the insert mode with the “EXIT” button) by operating the “ Add ”
button.
Fast navigation in the list is made possible by operating the buttons “ Start Page ”, “ Page End ” and “ Jump Row ”.
The following categories and assignments are available and/or possible:
- Assignment between function input/-outputs and function blocks. Predetermined in the device and not changeable
(see REFERENCE LISTS of the function in- and outputs)
- Assignment between digital in-/outputs and function inputs/outputs. Predetermined from user and changeable
- Assignment between flags, digital and function inputs/outputs. In the PLC program (statement list)
NOTE
Function outputs should not be changed with PLC commands because the function modules output results are biased.
Exceptions:
FO 425…552: PC control system outputs: Writing can be reasonable for handshake purposes.
FO 761...767: Load program and segment: These FOs are set by the function block and can be reset by PLC.
FO 824: Trigger for automatic alarm page display; see FOs 761...767
FO 1233...1352: Y-HAND active; the controller output is switched between manual and automatic by switching on
or off the FOs. Here is usually worked with “Set” and “Reset” but not with “=”.
FO 1257...1276: X-tracking active; activating and resetting the X-tracking is here possible. Here is usually worked
with “Set” and “Reset” but not with “=”.
FO 1281...1300: Y-tracking active; activating and resetting the Y-tracking is here possible. Here is usually worked
with “Set” and “Reset” but not with “=”.
FO 1321...01350: Set value manual active; the set value is switched between manual and automatic by switching
on or off the FOs. Here is usually worked with “Set” and “Reset” but not with “=”.
FO 2000...2799: Digital output variables; these variables are not assigned to a fixed function and can be read and
written by the PLC.
