Safety-oriented tripping

Description
Note:
Please note that the information made available for further processing is in
the form of non-safety-oriented signals.
Note:
Please note that the "Safe Tripping" function block is not a safety-oriented
tripping function.
The DM-F Local safety function is determined by the DIP switch setting on
the module only.
The DM-F PROFIsafe safety function is performed by the failsafe program in
the F-CPU.
The "DM-F Local Safe Tripping" function block consists of 3 sockets:
• Event - DM-F LOCAL ok: The DM-F Local is ready for operation.
• Event - Safe tripping: A safety-oriented tripping has been carried out.
• Status - Enabling circuit closed: The enabling circuit is closed.
The "DM-F PROFIsafe Safe Tripping" function block consists of 3 sockets:
• Event - PROFIsafe active: Failsafe communication between the F-CPU and the
DM-F PROFIsafe is active.
• Event - Safe tripping: A safety-oriented tripping has been carried out.
• Status - Enabling circuit closed: The enabling circuit is closed.
Overall one "Safe Tripping" function block is available for SAFETY (Local) or
PROFIsafe.
