Assigning operands at the output of a function block
The following operands can be assigned to the output of a QV function block:
• Markers such as MD, MW, MB,
• or the analog output QA.
Deleting operands on the function block inputs/outputs
Position the cursor on the required operand.
▶ Press the DEL pushbutton.
The operand is deleted.
Behavior of the function block editor with different operating modes
When working with the function block editor, the mode of the device is
important.
1. STOP: Access is possible to all parameters of the function blocks.
2. RUN:
• Only access to the basic parameters is possible.
• It is only possible to change input values at function blocks if they
are constants. The modified constants are used directly for
further processing in the circuit diagram.
• Pressing ALT enables you to toggle between setpoints and actual
values
Example:
• >I1 = Actual value, here from the output of the counter C 01
• >I2 = Constant 1095.
• QV> = Marker double word MD56
