Human machine interface for a remote terminal unit

A petrochemical measurement system, comprising:

• a remote terminal unit comprising a network data server and configurable using Modbus registers;
• a human machine interface (HMI) comprising an autonomous network data client in communication with the remote terminal unit, the HMI including:
• a memory having configuration parameter software stored thereon;
• a user interface configured to receive configuration parameter input using the configuration parameter software;
• a processor configured to send configuration parameters received from the user interface of the HMI to the remote terminal unit;
• and
• a monitoring and/or control system that maintains a configuration library for a plurality of flow meters, wherein the monitoring and/or control system is a supervisory control and data acquisition system (SCADA) or a distributed control system (DCS) coupled to the remote terminal unit, and wherein the remote terminal unit is coupled to the plurality of flow meters;
• wherein the human machine interface is integrated in a housing with the remote terminal unit and there is at least one other human machine interface located remotely from the housing;
• wherein the human machine interface and the at least one other human machine interface comprise a plurality of human machine interfaces that are simultaneously connected to the remote terminal unit;
• wherein the plurality of human machine interfaces are coupled in a client-server fashion with the remote terminal unit;
• wherein the monitoring and/or control system configures a new flow meter using information stored in the configuration library;
• wherein the monitoring and/or control system configures the new flow meter using contents copied from of a specific block of the Modbus registers in a database of the monitoring and/or control system to the new flow meter.
