Calling up function blocks from the circuit diagram
When you transfer parameters from the circuit diagram to a
function block, move from the circuit diagram editor to the
function block editor. Once you have assigned the
parameters, you will return to the position where you left the
circuit diagram with Save or Cancel. The operation is carried
out in the same way as with circuit diagram operation.
Example: Timing relay function block
Assigning operands to an > input of a function block
Assigning operands to a QV> output of a function
block
Deleting operands on the function block inputs/
outputs
Position the cursor on the required operand.

Function block: Timing relay
Switch function: On time with random switching
Time range: M:S (Minutes:Seconds)
Set time >I1: 20 min 30 s
Actual time QV>: Copied to MD96
h Only the following variables can be assigned to the input
of a function block:
• Constants, e.g.: 42,
• Markers such as MD, MW, MB,
• Analog output QA,
• Analog inputs IA,
• All output variables of the function blocks …QV>
h A variable output of a function block can only be assigned
markers such as MD, MW, MB or the analog output QA.
