Network Control of Safe Torque-Off Chapter 6
The SI.ConnectionStatus tags indicate the status of the safety input connection.
Safe Torque-off Assembly Tags on page 105 lists the SAFETY tags added to the
controller tags when a PowerFlex 527 drive is added to a GuardLogix I/O
configuration and the connection is configured for “Motion and Safety” or for
“Safety only”.
The “Attribute” values listed are the Assembly Object attribute values.
STO Fault Reset
If a PowerFlex 527 drive safety control detects a fault, the input assembly tag
SI.SafetyFault is set to 1. A transition from logic 0 to 1 of the SO.Reset tag is
required after the SO.SafeTorqueOff tag has transitioned from logic 0 to 1.
To reset Axis.SafetyFault, a MAFR command must be issued.

Type Description
SI.ConnectionStatus
(1),(2)
(1) Bits not listed are always zero.
(2) ConnectionStatus is determined by the Safety Validator in the GuardLogix controller.

SI.ConnectionFaulted [1] BOOL
SI.Status
(1),(3)
(3) The Status is sent from the drive to the controller using the CIP Safety protocol.

SI.SafetyFault [6] BOOL 1 = STO Fault present
SI.ResetRequired [7] BOOL 1 = A reset is required
SO.Command
(1),(4)
(4) The Command is sent from the controller to the drive using the CIP Safety protocol.
0x180 SINT
SO.SafeTorqueOff [0] BOOL 0 = Disable Permit; 1 = Permit Torque
SO.Reset [7] BOOL 0
→
1 = Reset STO Fault
ATTENTION: Only data listed in Safe Torque-off Assembly Tags on page 105 is
SAFETY data with SIL 3 integrity.
IMPORTANT
Transition of the SO.SafeTorqueOff tag to logic 1 must always be executed prior
to transition of the SO.Reset tag to logic 1.
IMPORTANT
PowerFlex 527 drives enter the STO Fault state if any STO function fault is
detected. Refer to
PowerFlex 527 Drive Troubleshooting on page 106 for
integrated safety troubleshooting.
