I would like to deploy Ignition on Linux cloud and communicate with 100’s of remote RTUs and PLCs via VPN. Windows based OPC UA servers are NOT suitable for remote management apart from stability and security issues.
Is there any linux based robust alternative for Windows based OPC UA servers like Kepserver?.
Can MQTT be used in place of OPC UA?.
A new protocol called “WOOPSA” claims to be a far better alternative to OPC UA and it can be deployed on Embedded devices, Linux, Node js etc.
