RE: EtherNet/IP MSGs cross the firewall fine, 1794-AENT I/O in the other zone gets 16#0204

Even with the rule I wouldn't leave that rack at 20ms across a firewall. Ping says 1ms, but a firewall adds its own delay under load, and at 20ms with...

RE: ControlLogix redundancy stays Disqualified after replacing a 1756-EN2T in the secondary

Same catalog number isn't the same module for redundancy. What series and firmware is the spare, and what's on the EN2T in the primary? Front of the m...

RE: Can't open an RSLogix 5000 v20 project on a laptop with Studio 5000 v33 and v36

Which v20 do you have on the disc, 20.01 or 20.05? The version matters. Studio 5000 starts at v21, it doesn't open v20 at all, and there's no convert-...

RE: Upload from ControlLogix has no rung comments or tag descriptions

RE: 1756-CNB replaced, RSNetWorx for ControlNet keeper mismatch, I/O will not schedule

RE: 1756-EN2TR DLR ring ran broken for six weeks before the cell went down

RE: Studio 5000 go online shows upload or download, offline file doesn't match

RE: EtherNet/IP MSGs cross the firewall fine, 1794-AENT I/O in the other zone gets 16#0204

RE: 1756-CNB replaced, RSNetWorx for ControlNet keeper mismatch, I/O will not schedule

No. The schedule lived in the keeper, but what you need to rebuild it is in the .xc file from commissioning and in the controller. Go online in RSNetW...

RE: Point I/O modules past slot 8 fault intermittently, 1734-AENTR itself is fine

How many modules exactly, what's in slots 1 to 20 in order, and is there a 1734-EP24DC anywhere in the rack? What's the AENTR firmware? A 20 module PO...
