Input
data Safety Input Data
SAFETY Indicates the ON/OFF state of each input circuit.
•
ON: 1 OFF: 0
Combined Safety Input Status
SAFETY An AND of the status of all input circuits.
•
All circuits are normal: 1
•
An error was detected in one or more input circuits: 0
Individual Safety Input Status
SAFETY Indicates the status of each input circuit.

Combined Safety Output Status
SAFETY An AND of the status of all safety output circuits.
•
All circuits are normal: 1
•
An error has been detected in one or more output
circuits: 0
Individual Safety Output Status
SAFETY Indicates the status of each safety output circuit.
•
Normal: 1 Fault (Alarm): 0
Muting Lamp Status
SAFETY Indicates the status when circuit T1 and T3 is configured
as the muting lamp output.
•
Normal: 1 Fault (Alarm): 0
Output Readback
STANDARD Monitors the presence of 24V on the output circuit.
Readback is ON (1) if 24V is on output terminal.
•
ON: 1 OFF: 0
Individual Test Output Status
STANDARD Indicates the status of each of the test output circuits.
•
Normal: 1 Fault (Alarm): 0
Input Power Error Bit Indicates field power supplied is within specification.
•
Power error: 1 Power OK: 0
Output Power Error Bit Indicates field power supplied is within specification.
•
Power error: 1 Power OK: 0
Run Mode Indicates whether consumed data is actively being
updated by a device that is in these states:
•
Run mode: 1 Idle State: 0
Connection Faulted Indicates the validity of the safety connection between
the safety producer and the safety consumer.
•
Valid: 0 Faulted: 1
Output
data Safety Output Data
SAFETY Controls the safety output.
•
ON: 1 OFF: 0
Standard Output Data
STANDARD Controls the test output when Test Output mode is set to
a standard output.
•
ON: 1 OFF: 0
IMPORTANT
Safety denotes information the controller can use in safety-
related functions. Standard denotes additional information that
must not be relied on for safety functions.
