CNET Blocks
If you select CNET in the General page of the Configure Control Options
dialog box, you can use CNET blocks to regulate communications
between the motion controller and other devices via ControlNet (CNET).
The following table presents the icons for each block in this category
along with a brief description. More detailed descriptions of the blocks
are contained on the pages following this table.
On CNET Status
If you enabled CNET in the Configure Control Options General page
dialog box, you can use the On CNET Status block to:
Use this block: To:
• Pause execution of the current task at this block until CNET
communications attains a specified CNET status condition.
• Branch program flow from this block, depending upon whether
a selected CNET status is true or false (If CNET Type).
Use this block to check the ControlNet interface and send the
resulting status value, or the location of the motion controller on
the ControlNet network, to the operator interface serial port.
Use the Reset CNET Fault 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.
