Using Kepware to connect to Rx3i and QuickPanel+ HMI

I am looking to connect to an Rx3i PLC, and a QuickPanel+ HMI (separate applications) using Kepware as proof of concept. 

Which communication technology/driver would be optimal for communication and reading data from both these systems?  

I have had success with the GESRTP driver for Rx3i, and I see SNMP can be used for QuickPanel+ HMIs but the Emerson/GE documentation on SNMP configurations is quite complicated and does not address any potential security risks or how to configure the panel with cyber safety in mind. 

Is there an optimal way to connect to both of these devices?  Any documentation/example videos (not specific to Kepware but any software would work)

    For the PACSystems RX3i, you can use SRTP or Modbus TCP. Latest CPUs support OPC UA. Support will depend upon CPU type and firmware version and may need enabling in the hardware configuration.

    For the QuickPanel+, you can configure Modbus TCP as a server in the application. Another possibility is to use OPC DA via PAC Machine Edition running on a PC on the same network as the QuickPanel+. SNMP is intended for network diagnostics only.
