<br>
I agree with Sebastian on the first two points.<br>
<br>
For the initial development time needed to support the IO devices, E Bus coupler and devices is much more easier! And Beckhoff has more options compared to Kollmorgen.<br>
<br>
But their price differences is not so big. At least in Turkey :)<br>
<br>
So it is up to you to decide.<br>

‎Hi! Oguz,<br>
Please review the below regarding Kollmorgen Coupler and recomend best course of action as you see..<br>
Thanks<br>

Subject: Re: [etherlab-users] ETHERCAT Bus Coupler Question<br>
<br>
Hi Ajith,<br>
<br>
1/ The Kollmorgen coupler you want to buy is a K-BUS coupler. It supports many<br>
fieldbuses but is not transparent for Ethercat commands.<br>
So it is more difficult to use with Igh Ethercat Master than a E-BUS coupler.<br>
<br>
2/ Kollmorgen has a very limited portfolio of I/O compared to Beckhoff, so it is<br>
an uncommon choice for modular I/O.<br>
<br>
3/ E-BUS couplers and I/O are cheaper than K-BUS ones.<br>
<br>
<br>
That is E-BUS?<br>
==============<br>
The physical layer of EtherCAT is based on standard Ethernet. Thus, standard MII<br>
is supported for stand alone devices connected to one another via CAT 5 cables.<br>
For more space and price sensitive devices such as modular devices another<br>
physical layer for EtherCAT is used, the so called EBUS.<br>
The EtherCAT protocol remains unchanged, only the physical form is changed.<br>
<br>

<br>
<br>
Consequences:<br>
~~~~~~~~~~~~~<br>
With E-BUS, the coupler is transparent for EtherCAT commands. Programming and<br>
debugging is easier. For example you can list all your slaves with 'ethercat slaves'<br>
Example on my system:<br>
<br>
$ ethercat slaves<br>

21 80:3 OP + EL3104 4K. Ana. Eingang +/-10V Diff.<br>
<br>
<br>
<br>
As you can see, I mix Kollmorgen AKD and Beckhoff E-BUS modular I/O without<br>
problem. I need only a single domain.<br>
