Patent ID: 7673298

Claim:
A computer-implemented method for verifying an effect of a software object on real time control before applying the software object to a customer's real-time control apparatus, comprising the steps of: downloading the software object from a first web site to a verifying real time control apparatus realized by a computer system for performing the real time control; applying the software object to the verifying real time control apparatus; evaluating whether the verifying real time control apparatus stably maintains the real time control or not even after the software object is applied to the verifying real time control apparatus by evaluating that a time margin of a real time task operating in the verifying real time control apparatus is not below a predetermined value in a state in which the software object is applied under a predetermined load being imposed on the verifying real time control apparatus to be operated for a predetermined time; uploading the software object which has been evaluated as one capable of maintaining a stability to a second web site; and the customer's real time control apparatus downloading the software object from the second web site to enable the software object to be applied, wherein the software object includes at least one of virus detecting software, a detection pattern file, and anti-virus software, for protection against computer viruses.
