666 Using AxisLink
However, the registration input of the physical axis to which the virtual
axis is linked must be activated or deactivated (as determined by the
Watch Control dialog box settings) to cause the registration event on the
virtual axis. See Watch Control in the Function Blocks chapter of this
manual for more information on registration. The registration status of the
virtual axis can be checked using either its Registration_status variable, or
an On Watch function block.
Virtual Axis System Variables
The following table shows the system variables that can be used with
virtual axes. See the System Variables chapter of this manual for specific
information on each of these variables.
