[Etherlab-users] What Hardware

[Karl Zeilhofer]

Hello users of EtherLab!

We are planing a retrofit a control system in the industrial field with
EtherCAT components.

* 500 digital I/Os
* 4 Analog Inputs
* 15 Analog Outputs
* SSI Input
* Some 9.6kbaud RS232 ports

Cycle Time should be in the range of 1 to 10ms.

What hardware would you recommend?

I have an offer for a Beckhoff IPC for around 2.000€ for an Core i7 with
4 LAN ports.
Another offer is about 800€ for a similar desktop system.

How critical is the decision for or against the supported Ethernet chip
sets (e1000, e1000e or r8169)? Would the generic driver be sufficient?

Kind regards,
Karl Zeilhofer
