Patent ID: 8051215

Claim:
An intelligent electronic device for provision in Substation Automation or Distribution Automation systems and comprising: an inter-module bus, a first interface to an external portable data carrier, and a number of hardware modules connected to each other via said inter-module bus, said modules implementing various functions of the device and including a process control module for handling at least one protection and/or control function, said process control module including a second interface to the inter-module bus, and a control unit arranged to sense, via said second interface, the types of hardware modules connected to the inter-module bus, obtain set-up data from an external portable data carrier connected to the first interface, said set-up data including configuration data relating to a protection and/or control function implemented by the process control module as well as verification data, said obtained verification data including hardware type data relating to the modules in the device, compare the obtained verification data with own verification data, which own verification data includes data regarding the sensed hardware type, and activate the protection and/or control function only if there is a match between all verification data being compared.
