Hi Ajith, I agree with Sebastian on the first two points.
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.
But their price differences is not so big. At least in Turkey :) So it is up to you to decide. Best regards, Oguz. 9.1.2018 18:26 tarihinde Ajith Boralugoda yazdı:
Hi! Oguz, Please review the below regarding Kollmorgen Coupler and recomend best course of action as you see.. Thanks Regards, Ajith Sent from my BlackBerry 10 smartphone.

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. Source: page 6 of EtherCAT Slave Implementation Guide https://www.ethercat.org/pdf/english/ETG2200_G_R_V1i1i6_ImplGuide_Slave.pdf 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.

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,
