Abstract
A method for communicating data between a first and second control system (FCS and SCS). FCS (202) controls a first process (FP) having first security data (FSD) in a first data security format (FDSF). The method involves modifying the FSD (214) from being in the FDSF into modified security data (MSD) in a modified security format (MSDF) compatible with SCS (226). Subsequent to the modifying, a request is received from an SCS user. The request includes a user type, process parameter (PP) associated with the FP, and request for information regarding the PP or a request to change a PP value. The method also involves referencing the user type and PP to the MSD. The method further involves blocking or allowing the request based on results of the referencing. If results indicate that the request is allowed, then an access level can be impersonated for changing the PP value in FCS.
