6.1 Manufacturer function blocks
For greater clarity, position the conditional jump function
block JC.. in the circuit diagram if possible directly in front of
the function blocks to be skipped.
If the error output is to be evaluated, position the standard function block in the stand-

suitable Boolean operand.
