Digital Module Operation in a Control System
Safe State
The following are the safe states of the safety modules:
• Safety outputs: OFF
• Safety input data to network: OFF
Figure 9 - Safety Status
The modules are designed for use in applications where the safe state is the
off state.
ATTENTION:
• The safe state of the outputs is defined as the off state.
• The safe state of the module and its data is defined as the off state.
• Use the Compact 5000 I/O safety modules only in applications where the off
state is the safe state.
IMPORTANT
If you inhibit a safety module from transitioning to a safe state when a fault
occurs because an I/O connection is lost, you accept responsibility for any
consequences that result from your decision to inhibit.
We recommend that you use other means to maintain the safe state if you
inhibit the safety module from transitioning to a safe state.
