Abstract
An industrial controller for safety control is disclosed. The controller comprises an interface for receiving a download of a safety control program, a memory for storing at least one safety control program and at least one processing unit for executing a safety control program stored in the non-volatile memory. The at least one processing unit is configured to determine whether a safety control program is verified and to limit an execution of an unverified safety control program according to an unverified run mode. An indicator is configured to indicate the execution of an unverified safety control program. A method of assigning a verification ID to an industrial controller comprises steps of configuring and downloading a safety control program, validating the configured safety control program for the target industrial controller, and assigning a verification ID. Execution of the configured safety control program is limited before the verification ID is assigned.
