Data Description
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.
• Normal: 1 Fault (Alarm): 0
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.
