Equivalent to system.device.setHostname for opc

[SWoollett]

I'm was going to implement redundancy for my OPC-DA connections as discussed here by updating the hostname in the gateway configuration directly.

Indirect OpcItemPath

Kevin beat me to it, here's a brief description on what to do. Your connection names can obviously be whatever you want. For communication between primary and secondary devices with different addresses/hostnames, create 3 device connections Device connection “A” Device connection “B” Device connection “Master” Connections “A” and “B” will only be used for reference to the diagnostics to determine a device connection Tags used throughout the project will reference the “Master” connection A G…

However, found that as the OPC-DA connections don't appear in system.devices.listDevices

looking at the system.opc options there doesnt seem to be a similar option to system.device.setDeviceHostname

Anyone able to provide if there is some other option I should look at to update the OPC hostname directly?

For some background, we currently have redundancy setup per tag by updating the tag OPCServer but are not happy with this implementation so looking to simplify it
