386 CNET Blocks
MAC ID
When you select MAC ID from the Show menu, the address (or Media
Access Control ID) of the local controller appears as an integer value,
from 1 to 99. The MAC ID value is set in the CNET page of the
Configure Control Options dialog box.
Reset CNET
If you enabled CNET in the Configure Control Options General page
dialog box, you can use the Reset CNET block to clear all ControlNet
faults and to reset the ControlNet card in the motion controller. This
block sets the ControlNet global fault variable (Global_fault = 16) to
zero.
The Reset CNET block resides on the CNET Palette. To configure the
Reset CNET Fault block, in the Type field select:
• All Faults – to clear the CNET_fault variable (Global_fault = 16) by
resetting it to zero, or
• Plug – to reset the ControlNet plug card in the motion controller,
thereby returning both the CNET_fault variable (Global_fault = 16)
and the CNET_status variable to zero.
Use this block to reset CNET communications only after you have
determined and fixed the cause of the fault or failure.
