Configurable process control device with electronic display assembly

摘要

A configurable process control device, which includes a field device, such as a valve position controller, that can be configured by a user to emulate any one of a plurality of different types of process control devices, is provided with an electronic display assembly. The electronic display assembly is operatively connected with a control circuit that is arranged to respond to the specific configuration of the field device to cause the electronic display assembly to display information relevant to the specific type of control device the field device has been configured to emulate. The information may include safety certification information specific to each of the different types of process control devices that the field device can be configured to emulate.

主权项

1. A configurable process control device for use in a plurality of use environments, wherein at least one of a pre-defined plurality of certifications must be displayed in conjunction with the configurable process control device depending on which of the use environments the configurable process control device is to be used in, the configurable process control device comprising:
a field device comprising a magnetic proximity sensor switch; a first control circuit operatively coupled to the field device, the first control circuit arranged to control the field device and arranged to be reconfigured by a user to allow the field device to selectively emulate at least two different switch types, including at least one of a numar switch, a dry contact switch, a PNP switch, and an NPN switch; an electronic display assembly, the electronic display assembly arranged to selectively display different information; and a second control circuit, the second control circuit operatively coupled to the electronic display assembly and the first control circuit, the second control circuit having access to a plurality of different certification information sets, each certification information set corresponding to a different one of the at least two different switch types; wherein the second control circuit causes the electronic display assembly to display a selected one of the certification information sets corresponding to the switch type the field device has been selected to emulate.
