The following rules apply to the safety circuit diagram:
• Rule 1:
Wire coils Ix of the safety function blocks directly to the
contacts of the device inputs ISx. Branches and connec-
tions to other contacts are not permissible.
Correct:
Incorrect:
• Rule 2:
If a device input was assigned to the input of a safety func-
tion block in accordance with rule 1, the device input must
not be assigned to any other channel input of a safety
function block.
Correct:
Incorrect:
• Rule 3:
Currently not defined.
• Rule 4:
A safety circuit diagram must always be provided.
• Rule 5, 6 and 7:
Currently not defined.
• Rule 8:
A non-safety coil of a safety function block - normally the
EN coil for the external enable of the function block -
should only be assigned once, either in the safety circuit
diagram or in the standard circuit diagram.
• Rule 9:
Use the safety device outputs QR and QS as a coil only
once, either in the safety circuit diagram or in the standard
circuit diagram. In other words, a device output used in
