RS Linx Ethernet Issue

[Mac 1]

I am having an issue with a network that I have 4 Identical machines on. I'm using RSLinx 2.59.02. Each machine has a contrologix plc, Powerflex70 drive and a panelview 1000 all connected by ethernet. I have all 4 machines on a switch connected to a machine server. When I use my laptop to view the network from my bench I see everything in the tree except for 3 of the 4 PF70's? 1 shows up fine but the other 3 show up as unrecognised devices. They are all identical machines with the same settings? I can ping all of them at the command prompt so I know they are there but Linx won't recognise them? Any ideas? Thanks in advance

i would guess all the PF70's are not actually identical......probably a slight version mismatch......in that case you need to update the EDS file for RSLinx...maybe you didn't load them all or perhaps those three drives are newer than your RSLinx install. You should be able to see the version either from RSLogix5000 or using the drive configuration software. bob
