I'm getting this error when I try to execute the program. Some background: Using an external driver and DMC-4080 to control a stepper motor. Connections are made through the 26-Pin Axis A port. Here is the program that I am currently writing:

#AUTO
'Assign IP to controller'
IP 192,168,142,10;
LU 0; 'shut off automatic updating to display'
MG "Test 1";
