Thanks Splash, The FactoryTalk Linx Network Browser's ethernet driver list option supports a range option that can be helpful in your case. The one downside is each time the browser polls an IP address that does not have an associated device, an ARP message will be sent by the gateway of the subnet. ...

FactoryTalk Linx currently supports discovery of devices both types, but the detection is dependent on network / IT settings.
