Hi all,
I've got a customer who quite often needs remote support at various sites, and he asked if there was a device I could give him that would allow him to have me connect to a PLC remotely. The e w o n Cosy 131 probably fits the bill - throw in a sim card, power it up, and I can remotely connect to it. Obviously, I'll have to configure the e w o n to be on the same subnet as the PLC on the LAN side - no problems there. But what I'm not sure of is, will the PLC need the gateway address set to the address of the e w o n to work? I'm not sure whether the e w o n...
- Passes the data from my programing laptop back and forth over the VPN and acts as a gateway, meaning I would need to set the gateway address of the PLC before it would work, or
- Directly receives my data and sends it to the PLC as if it were itself the programming laptop, and then when the PLC responds to it, passes the data back
Can anyone confirm?
