SO why does it state ?
"Serial port (DB9 female connector), supports serial protocols RS232, RS422, R485 (SW-configurable) for end point PLC control."
What does endpoint PLC control really mean ...
- Connection from a plc to the gateway over serial ?
Where would that be usefull ? (or even allowed) ?
- Connection from the gateway to a plc through console ?
That looks to me like something useful
It's really confusing if you can't find anything more detailed on that matter 🙂
It has a console port in the form of usb-c
Also, the device has almost everything.
- GPS, 4G backup, WAN, DMZ, 8 bridge or separate switch ports, dual power supply, usb, serial, wifi...
This seems to me like a missed opportunity, maybe from security standpoint I'm missing something... but from a critical gateway with built-in resilience features and robustness, it would be a great addition if this could connect to a serial console from another device.
