Title: BX 10/10E MPU
Post by: HB_GUY on February 23, 2017, 07:46:07 PM
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.

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.
