Just a question on the BX 10/10E MPU units.
Limited to 2 expansion modules?
All other cpu's state that 8 modules can be added...

To keep the price as low as possible, we choose to reduce power supply capacity. Also had space constraints that prevented the bigger capacity supply.
-
So does that then also apply to the no I/O unit?
-
No both the modular versions BX-DM1E-M and BX-DM1E-M-D support up to 8 Expansion modules.

Cool! Is there a BX-EBC coming?

Yes, in two forms. A general purpose BX-EBC100 in the modular form, and a line of Do-more specific I/O bricks that will be identified as BX-DMIO-xx. Specific I/O mix is still being decided, but we expect all of the most common variants in -10, -18, and -36 housings. Those bricks will also support discrete and analog expansion.
When we're done with this, you'll be able to build very large BRX systems.

Egggggselent! [schemy fingers]

Not that I have any multi-rack BRX projects in the chute, but for now the standard remote I/O is going to be 205 or Terminator I/O using Do-More RIO protocol, or whatever else we want to use, with Modbus/TCP or RTU?

BRX Ethernet I/O support is identical to H2 and T1H, so yeah EBC100s work fine with it, as does anything Modbus. We hope to have the DMIO products out by summer-ish.

Cool. It actually will be nice to have multiple families of I/O to choose from so we can mix and match and pick the best fit for whatever I/O is connected to a given node.

Speaking of RIO... I am working with EtherCAT on my current project... Unbelievably fast! :o :o :o

We think we can probably get synchronous with BRX DMIO. How fast is EtherCAT?

I believe I am getting around 10 microsecond response time on the physical IO, and around 50 microseconds through the processor.

What is the processor?

This is using InTime RTOS on a PC talking to Beckhoff EtherCAT nodes.
