• Rule 20:
The I debounce function must not be switched on for
inputs that you have used in the safety circuit diagram.
• Rule 21:
Only wire the device outputs in the circuit diagram that are
the physical device outputs. For example, not every device
variant has the redundant relay output QR.
• Rule 22:
Currently not defined.
• Rule 23:
If the easySafety is run as a stand-alone device (i.e. not in
the NET network), you cannot connect NET operands or
NET function blocks (e.g. PT, GT, SC) in the standard
circuit diagram or standard function block diagram.
• Rule 24:
Some safety function block inputs can only be wired once
as a coil. The reported input of the safety function block
has been wired several times as a coil in the safety circuit
diagram.
• Rule 25:
Currently not defined.
• Rule 26:
Do not assign a test signal to the inputs IS1 and IS2 if an
OM or ZM function block is present in the safety circuit
diagram. OM and ZM are assigned implicitly IS1 and IS2
as measuring inputs for the frequencies.
• Rule 27:
If you are using the SG (safety gate) function block in the
operating mode 1L or 2L (with guard locking monitoring)
the startup test (SUT parameter) is not possible.
• Rule 29:
A NET operand should always have a NET ID assigned to
it. However, the NET ID must not be the same as the NET
address.
• Rule 30:
QS device outputs that you have used as coils in the
standard circuit diagram must not be used as contacts in
the safety circuit diagram.
