  1. Hello, I wanted to know if it is possible to create a user defined function in Ladder Logic when programming through Studio 5000. I intend to write a specific logic, then move it all into one single block (the "function"). Can I then just call this one single block later into the program, instead of having to write all the logic once again? Thanks.
  2. Hi, I am intending to emulate a ControlLogix 5571 PLC (on qemu probably). I am looking for relevant information about the CPU architecture, but it is nowhere to be found. The only leads I have thus far is 1. It a dual core CPU 2. It *might* be a 32 bit Power Architecure What is the architecture of the CPU in this controller? None of the Allan Bradley literature manuals have any information on this, at least to the best of my knowledge. Any help is appreciated.  Thank you. 
  3. Interfacing a ControlLogix 5571 PLC

    Hi kaiser_will, Thank you for sharing those work instructions. Those should be good help. It's sad that there is no other way to interface with those PLCs. Should you / anyone have any leads whatsoever, kindly send them my way. Thank you.  
  4. Hello, I intend to connect to a ControlLogix 5571 PLC through a work station and program it. One way is to install the RSLinx driver and then use the Studio 5000 (RSLogix) to upload / download projects onto the PLC. Is there any other way for doing the same? Is it possible to connect to the PLC serially (through the USB) and run a client like PuTTY / serial consoles (minicom, picocom) on the workstation, and then interface with the PLC? Also, I have one other query. What is the firmware that is running on the PLC? Is it VxWorks OS? Or some modification?  Any help is appreciated.  Thank you.
