Hi Les, You can extend the I/O of a 7i76 or 7i77 with one smart serial card and a cable

Hi JT, Looking through your website the 7I92 + 7I77 combo looks promising. It would definitely work for the mill but I need to check if there are enough I/Os for the router. I also have a suspicion the current control on the router switches to ground rather than +24. Les On 14/01/17 15:20,

Hi Les, I have both of those in stock at http://mesaus.com/ The cool thing about the 5/5i24 is you can connect an Opto 22 base to one port and have a lot of I/O. JT On 1/13/2017 5:09 PM, Les Newell wrote: > I have a couple of rebuild projects coming up (a router and a milling > machine) and

Thanks Sam, The router's servo drives are old and probably wouldn't gain any benefit from going greater than 1kHz. The mill is a bit more up to date but again 1kHz is probably enough. It's not a high speed machining centre. Chris, the hardware does the very fast stuff such as encoder counting

I have used both. If you need higher servo thread speeds (>2khz depending on hardware) Stick with pci/pcie. The matsuura was converted using mesa ethernet. (7i80+lots of other daughter boards) while configuring the machine - the computer / mesa hardware was up for weeks on end - with

2017-01-13 Thread Les Newell
I have a couple of rebuild projects coming up (a router and a milling machine) and I am trying to decide between PCI or Ethernet. I like the idea of Ethernet because it will probably be around long after PCIe has disappeared but the idea of it running in user space instead of realtime makes me
