[etherlab-users] ETHERCAT Bus Coupler Question

‎Hi! Sebastian,
To tell you the reason I went Kollmorgan direction is the availability of helpful professional distributor for the reagion.
The Beckhoff distributor ti whom I was directed by Beckhoff was pretty useless!!!
So Even if I want to get the EK1100 I am not sure the support will be there for me to fall back in case if I needed.!!!
I very much see your point and let me see whether I can get this resolved with the Kollmorgan distributor through their contacts in India.
Sri Lanka where I live does not have much of Systems integration happening and even the distributors for Beckhoff are ‎not as though as in Europe for instance.
Now with Kollmorgan drives I need to select right terminal blocks for EK1100 too.
Since Ineed Spindle and Drive too which was available with Kollmorgan not too sure about Beckhoff.
Perhaps you cn shed more light on this aspect.
But thanks, I can see why not make my life easier even though Kollmorgan coupler might work with few different domains as responded by‎ Ogu. In the forum
Looking for,ward to your response on the above
Regards,
Ajith

Hi Ajith,

1/ The Kollmorgen coupler you want to buy is a K-BUS coupler. It supports many 
fieldbuses but is not transparent for Ethercat commands.
So it is more difficult to use with Igh Ethercat Master than a E-BUS coupler.

2/ Kollmorgen has a very limited portfolio of I/O compared to Beckhoff, so it is 
an uncommon choice for modular I/O.

3/ E-BUS couplers and I/O are cheaper than K-BUS ones.


That is E-BUS?
==============
The physical layer of EtherCAT is based on standard Ethernet. Thus, standard MII 
is supported for stand alone devices connected to one another via CAT 5 cables. 
For more space and price sensitive devices such as modular devices another 
physical layer for EtherCAT is used, the so called EBUS.
The EtherCAT protocol remains unchanged, only the physical form is changed.

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

$ ethercat slaves
0 1:0 OP + EK1100 EtherCAT-Koppler (2A E-Bus)
1 1:1 OP + EL5001-0011 1K. SSI Monitor
2 1:2 OP + EL5021 1Ch. Sin/Cos Encoder
3 1:3 OP + EL5001-0011 1K. SSI Monitor
4 1:4 OP + EL1809 16K. Dig. Eingang 24V, 3ms
5 1:5 OP + EL1809 16K. Dig. Eingang 24V, 3ms
6 1:6 OP + EL1809 16K. Dig. Eingang 24V, 3ms
7 1:7 OP + EL2809 16K. Dig. Ausgang 24V, 0.5A
8 1:8 PREOP + EK1521-0010 1-Port EtherCAT-Abzweig (FX-SingleMode)
9 30:0 PREOP + EK1501-0010 EtherCAT-Koppler (2A E-Bus, FX-SingleMode, ID-Switc
10 30:1 OP + EL5021 1Ch. Sin/Cos Encoder
11 30:2 OP + EL1809 16K. Dig. Eingang 24V, 3ms
12 30:3 OP + EL2809 16K. Dig. Ausgang 24V, 0.5A
13 30:4 PREOP + EK1122 2-Port EtherCAT-Abzweig
14 51:0 OP + AKD EtherCAT Drive (CoE)
15 52:0 OP + AKD EtherCAT Drive (CoE)
16 53:0 OP + AKD EtherCAT Drive (CoE)
17 54:0 OP + AKD EtherCAT Drive (CoE)
18 80:0 PREOP + EK1100 EtherCAT-Koppler (2A E-Bus)
19 80:1 OP + EL1809 16K. Dig. Eingang 24V, 3ms
20 80:2 OP + EL2809 16K. Dig. Ausgang 24V, 0.5A
21 80:3 OP + EL3104 4K. Ana. Eingang +/-10V Diff.



As you can see, I mix Kollmorgen AKD and Beckhoff E-BUS modular I/O without 
problem. I need only a single domain.

best regards,
