Hey all,
I've been reading a lot about managed switches for a project we have coming up that is going to have upwards of 50 different ethernet devices on it. They will be ranging from Robots, Remove I/O, Drives, HMI's, and PLC.
When is it necessary to use a managed switch and what all would I need?
I read through this post: http://www.plctalk.net/qanda/showthread.php?t=68028&page=4
and it has a lot of good information.
Most of our devices are going to be setup to use Unicast over EtherNet/IP, does this make a managed switch redundant if I am staying on the same LAN for all devices?
We typically stick with the default 192.168.1.xxx scheme so everything on 1 subnet talking to eachother.
This is going to be done using a compactlogix so 1 ethernet card built in.
My game plan was to use unmanaged switches in most of the cabinets then have those run to a managed switch like a STRATIX 6000 or another similary priced managed switch then run that to a master switch that has layer 3 in case automation network is desired to be hooked into business network. that way the layer 3 switch can keep the 2 separate but also allow people to connect to devices on the automation network.
After reading about the managed switches and IGMP Snooping it seems like maybe that is not too beneficial seeing as most our devices use Unicast, is this correct?
