You use a laptop to write ladder logic that is downloaded to PLC.  This company has fantastic tech support that will bring you through specifying what modules to buys, pointing you to you tube tutorials and helping you debug the ladder logic if you get stuck.

There is a bit of a learning curve but if you can write basic, you can write ladder logic.

Cliff,   What brand of PLC are you using?   Can you program it in basic?

Two aft thrusters that are fixed horizontally are used for forward, reverses and yaw control.  To fixed vertical thrusters located in wings for vertical depth station keeping, pitch and roll control. Each will have a dedicated minn Kota motor controller.  0-5vdc analog output signal to each motor controller will come through PLC analog output module.  A analog input module of the PLC will accept signals from a 3-axis joystick and a foot control.

Cliff,
>Since you are replacing the jet drive with a pair of fixed 
101's, what are you doing to achieve low/high speed maneuverability?  Did I 
misunderstand about your main thrusters being fixed?  Are you incorporating 
rudders, dive planes, additional maneuvering motors?

propulsion and maneuvering system that is quite and easy to maintain.  In a 
few months, I will let you know if I was 
successful.
