Hi. I have an application where I need 2 servo motors that are mechanically linked to run a gear box (motor A is connected to motor B via 2 independent shafts and an idler gear). This is a ControlLogix system using Kinetics 6k drives with a 1756-M16SE card in the rack. Also, the gear box has to run at a given velocity. It's not position dependent. So I'm wondering what is the best way to do this. At first I was thinking to have motor A geared to motor B (both in velocity loop) and just limit the torque on motor B. Or possibly even gear both to a virtual axis. But now I think a Torque Following type of solution would be best. I know that Torque Following is possbile when using VFDs but I don't know how to do this with ControlLogix and Kinetics 6k. Any helpful ideas would be greatly appreciated. Thanks

I haven't purchased the F2-DEVNETS-1. I was looking on the website for info but all I could find was an overview brochure. I started digging a little deeper and eventually did find the manual. I shouldn't need much more than that but thanks for the reply. Although, if you have any experience with this module and could let me in on any tips I'd appreciate it (I'm new to Automation Direct, usually program A-B and Siemens). Again, thanks for the response.

Hi, I have an application where I need to setup communications between a DirectLogic 205 controller and an ABB Robotics controller. The ABB controller has a DeviceNet CANOpen comms module. I was thinking of using a F2-DEVNETS-1 DeviceNet Slave module but I would like some technical info on how it communicates and how to set it up. Can anyone point me in the right direction? If there is something that work better other than the F2-DEVNETS-1 I would love to hear about it. Thanks

Thanks guys for all of the replies. I will keep in mind the thoughts and advice from paulengr. I didn't know about the hands on lab. I'll have to check that out.

Thanks guys for the replies. I was just looking for something simple and quick that explains the different components of an SFC, how they work, and maybe gives an example. I'm pretty familiar with Logix5000 but I've never done SFC programming. I do have the "SFC and ST Programming Languages" manual. It's just that I learn a little better if I see it done. Maybe I'll try it in a test program and post the code here for critique like you suggest KidPLC. Thanks again

Does anyone know where I can find a good tutorial on SFC programming in Logix5000? I have version 17 installed. I tried reading the manual from Rockwell but a video tutorial would help me a lot. Thanks
