Example – Ethernet Communication Error
This simple program executes in the IOC-7007 and indicates (via the serial port) when a
communication handle fails. By monitoring the serial port, the user can re-establish communication if
needed.

Begin thread 1
Create new variable
Set KP to value of N, an invalid value
Issue invalid command
End of thread 1
Begin command error subroutine
If error is out of range (KP -1)
Set N to a valid number
Retry KP N command
If error is invalid command (TY)
Skip invalid command
End of command error routine
