362 AxisLink Blocks
The AxisLink_general_fault variable indicates whether or not the
attempted AxisLink connection was successful. It has a value of 1 (true) if
there has been an AxisLink timeout attempting to read the value from the
remote motion controller and 0 (false) if not. When
AxisLink_general_fault = 1, Global_fault = 8 if no other faults of higher
priority are active on any axis.
When an Axislink_general_fault has a value of 1 (true) due to an
AxisLink timeout attempting to read the value from the remote motion
controller the AxisLink_fault_code = 64-79.
User Variable Type
When you select User Variable from the Type menu, the local motion
controller reads a value from the selected remote motion controller’s
selected user variable number, and stores that value locally in a selected
user variable.
Data Type
When you select Data from the Type menu, the local motion controller
reads either the current working state of the data bit, or the current
working value of the data parameter, from the selected remote motion
controller, and stores that value locally in a selected user variable.
Data Bits and Data Parameters
The available data bits and data parameters are displayed in two separate
tables in Miscellaneous Blocks chapter and explained in the Setup section
of the Installation and Setup manual for your motion controller.
Reset AxisLink Fault
The Reset AxisLink Fault block directly clears any and all AxisLink axis
specific faults on the selected virtual axis by disabling the axis and setting
the value of the AxisLink fault variables for the axis to zero.
The Reset AxisLink Fault block resides on the Advanced Motion Palette.
