I am currently designing a fieldbus architecture and would like to know if I have no inconvenience in using two or more remote I/O modules under the EtherCAT bus using a small industrial switch for it. I have worked in the past with only one Weidmüeller module. Currently I have one Weidmüeller remote I/O module and another one from a welding system manufacturer that also has its configuration file. I intend to use the EtherCAT bus of the KRC4 and connect it to a switch where the two mentioned devices are located. Is there any restriction for this?
Thanks in advance
