Gateway offering logical model mapped to independent underlying networks

A method comprising:

• communicating over a first industrial process control network using a first protocol via a first interface;
• communicating over a second industrial process control network using a second protocol via a second interface;
• communicating with at least one supervisory device over a third network via a third interface;
• and
• providing concurrent access for the at least one supervisory device to process control devices coupled to the first and second industrial process control networks during a migration of process control devices that use the first protocol to process control devices that use the second protocol.

A non-transitory computer readable medium embodying a computer program, the computer program comprising computer readable program code for:

• initiating communication over a first industrial process control network using a first protocol via a first interface;
• initiating communication over a second industrial process control network using a second protocol via a second interface;
• initiating communication with at least one supervisory device over a third network via a third interface;
• and
• providing concurrent access for the at least one supervisory device to process control devices coupled to the first and second industrial process control networks during a migration of process control devices that use the first protocol to process control devices that use the second protocol.
