Micrologix 1100 and stepper drive

[Rookie77 0]

Hey guys, 

Really in a pinch here, our stepper drive seems to have somewhat died..... IIhave output pulses going from the micrologix 1100 to the +step but nothing is moving. I can connect to the sure  step program and move in test mode and scl. 

 

I need this machine running for Wednesday, is there any way someone can give me an example of how to send serial commands to the drive? It's  something I have done yet (still relatively new to this) but if I could get some basic commands going, I'm sure I can make with the bags bones system to the drive arrives
