Typing the IPaddress via the IED Object Properties dialog box is possible at any time whileentering it via the configuration wizard can only be done when adding the IED object.1. In the Plant Structure view, select the IED to which the IP address is to be entered.2. On the View menu, select Object Properities.Object Properties dialog box is opened.3. Type in the IP address to the IP Address row.4.8 Technical keyBoth a physical IED and an IED object in PCM600 have a technical key. The technicalkey in the IED and PCM600 must be the same, otherwise it is not possible to downloada configuration.Each IED in a PCM600 project must have a unique technical key. Therefore, it is notpossible to set the same technical key for several IEDs in the same PCM600 project.The IED is delivered with a factory default technical key. Thevalidation of the technical keys between PCM600 and the IED does notoccur if the IED contains the factory default technical key.Section 4 1MRS240044-IB ASetting up a project46 REF615REngineering Manual
