1. A verification device for verifying a plurality of different types of field devices installed in an industrial factory process plant, the verification device comprising:
a. a communication adapter having a communications port configured to communicatively connect the verification device to a plurality of different field devices including a first type of field device and a second type of field device to receive values of one or more operational parameters measured by the plurality of field devices;
b. a repository comprising a plurality of verification definition data sets each associated with one of the plurality of different field devices, including a first verification definition data set associated with the first type of field device and a second verification definition data set associated with the second type of field device wherein each verification definition data set comprise one or more sets of expected threshold values of one or more corresponding operational parameters for a corresponding type of field device from among the plurality of different field devices; and
c. a comparison and verification processor configured for:
i. receiving, as externally provided electronic data, a device type identifier that is uniquely specific to one of the first type of field device or the second type of field device;
ii. obtaining, from the repository, one of the first verification definition data set or the second verification definition data as is associated with a type of field device under verification from among the plurality of different field devices, based on the device type identifier of the field device under verification;
iii. measuring one or more values of one or more operational parameters received from the field device under verification as defined by the first verification definition data set or the second verification definition data set as obtained;
iv. comparing the measured values of the one or more operational parameters with corresponding threshold values of the one or more operational parameters from the first verification definition data set or the second verification definition data set as obtained for the corresponding field device under verification, wherein the corresponding threshold values for the corresponding definition data set comprises a first set of threshold values and a second set of threshold values of the corresponding operational parameters, wherein the threshold values of the first set are based on reference values of the operational parameters at the production of the field device, and the second set are based on the operational parameters measured upon installation of the field device under verification in the industrial factory process plant; and
v. determining a condition of the field device under verification from among the plurality of different field devices based on the comparison.
