We ship a labeller with a CompactLogix 5069-L320ER, a PanelView Plus 7 and a FactoryTalk View SE station for recipes. The support contract says remote diagnostics within four hours, and on the bench that means unattended TeamViewer on the SE PC with Studio 5000 going through it.
New customer's IT has said no. TeamViewer isn't going on anything that touches the line. We offered it with a long password and their approval before each session, then a 4G modem straight on the PLC's second port, which got a louder no and a meeting. So we're stuck.
I don't want to argue with their IT, they're right I think, but I need a way in that plants will actually accept. What do plants actually sign off on for an OEM, because I need something to put in the contract before the next one ships?
Start from what leaves the plant, not what comes in. Their IT said no to a desktop sharing tool because it's a full session on a Windows box on the line, doing whatever the far end wants. Does the labeller PC need to be reachable at all, or only the PLC and the panel?
> only the PLC and the panel
Mostly the PLC, Studio 5000 online, and the panel for pushing a screen fix. The SE station is only recipes, I don't need to see it. The machine subnet is 192.168.10.x and that's all I've ever needed. The 4G modem was the same thought really, reach 192.168.10.x and nothing else. They didn't see it that way.
