New Project questions

Wit our cards, probably the simplest way would be to use a 5I23, for the controller, a 7I33TA for the analog servo/encoder interface, a 7I44 for High speed RS-422 interface and 2X 7I70s for Field inputs and 1X 7I71 for Field outputs
This combination of cards would give you 4 Axis of analog servo interface, (4 encoder inputs and 4 +-10V analog outputs). The 2 7I70s would give you 96 24V inputs and the 7I71 would give you 48 24V outputs

This leaves one FPGA connector and 5 high speed RS-422 channels free for expansion
This configuration will require EMC2.5 to support the 7I70 and 7I71.

The 7I70 and 7I71 connect via CAT6 cables ("Ethernet cables) and can be up to 100 feet from the controller. Sometimes this can help with wireing

Thank you....With the help of this Forum that is exactly the set-up I was gravitating to. The 5I20,7I33Ta,7I46 and three pieces of the 7I64.

I am sure over the next few months or so I will be a regular on here. I really just wanted my ticket stamped before I spent the money on the wrong hardware.

I do have another question on the computer. You mentioned the ATOM and it has on board Video. I read somewhere that on board Video could be a problem. I do have a few computers laying around but would like to start all new on this project.

As a beginner would I be getting in way over my head with the EMC2.5? I will need every bit of support I can get to get this thing on line.

The on board video of the Atom boards appears to not be any problem at all, the latency numbers
are great, even when playing around with video hogs like glxgears. I have tested both the
D510MO and the D525MW motherboards.

I think that the Pico PPMC is parallel port only, but you can always add another p-port or two if you need more IO. Note that it uses the p-port as a communications port, not as individual pins like the cheap stepper systems.

The PPMC allows up to 16 board of your choice to be run off a single parallel port.
It is possible to daisy-chain two motherboards together to get the 16 board slots.
No one has ever needed to even use the second motherboard.

If you wanted to use the PPMC with lots of additional I/O, then maybe the
Vigilant or Vital Systems multi-IO board would do it.
