Example - Communication Interrupt
A DMC-4010 is used to move the A axis back and forth from 0 to 10000. This motion can be paused, resumed and
stopped via input from an auxiliary port terminal.

STA;ZS;EN
Stop motion on A axis; Zero program stack; End Program
#PAUSE
Routine for pausing motion
rate=_SPA
Save current speed setting of A axis motion
SPA=0
Set speed of A axis to zero (allows for pause)
EN1,1
Re-enable trippoint and communication interrupt
#RESUME
Routine for resuming motion
SPA=rate
Set speed on A axis to original speed
EN1,1

For additional information, see section on Using Communication Interrupt.
Example – Ethernet Communication Error
This simple program executes in the DMC-40x0 and indicates (via the serial port) when a communication handle
fails. By monitoring the serial port, the user can re-establish communication if needed.
