Our current plant is running on DH+ and we are trying to slowly change everything over to ethernet. We have 1 complete line already set up on ethernet and we added a unmanaged hub in ceiling where we have a control logix rack we are using for communacation purposes only. We simply added a hub and added a ethernet bridge in chassis, this works however this is a very slow connection "actually our DH+ is much faster, we cannot do any edits online without being booted", I think we need a managed switch but not sure how to go about it or what type of switch we need? Fixed or Modular?
