• 1 (true) if there has been an AxisLink timeout attempting to access
another motion controller’s AxisLink outputs or data
• 0 (false) if not
In the Tag Explorer select General System Variables, then select
AxisLink_general_fault in the Tag Window.
When evaluated in an expression, the value of the AxisLink_general_fault
variable indicates whether a fault has occurred attempting to access
another motion controller’s AxisLink outputs or data.
When AxisLink_general_fault = 1, Global_fault = 8 if no other faults of
higher priority are active on any axis.
You can directly clear an AxisLink general fault by using a Clear
AxisLink Fault block, or assigning a value of 0 to the
AxisLink_general_fault variable using an Equation block. However, this
does not automatically re-enable the AxisLink connection to the other
motion controller. See AxisLink Fault Code for more information on the
conditions that cause this fault and how to clear them.
AxisLink Fault Code
AxisLink_fault_code is an integer value representing the highest priority
condition causing an AxisLink general fault, as shown in the table below.
In the Tag Explorer select General System Variables, then select
AxisLink_fault_code in the Tag Window.
