Abstract: A method and system are provided for validating process data on a process recorder/controller. The method and system involves: configuring the validation criteria of the process variables, by defining value and time tolerances with respect to an ideal performance; receiving in real-time process data, including one or more process values, for a batch process at the recorder/controller responsible for recording the process data; performing a batch validation process on the recorder/controller, the batch validation process analyzing in real-time the one or more process values to validate the batch process based on at least a batch validation criteria; and transmitting from the recorder/controller validation information including a validation result for presentation on a device to a user, and/or recording at least on the recorder/controller the validation information including at least the validation result, wherein the validation result indicates whether the batch process is conformant or non-conformant.
