The engineering tools assists you in your workflow from planning to operation of your systems with SIPROTEC and Reyrolle devices. With DIGSI 5, you have full control over the engineering. The functional scope of the tool covers all tasks – from device configuration and device setting to commissioning and evaluation of fault data with SIGRA. The SIPROTEC DigitalTwin is the real time digital replica of a physical SIPROTEC 5 device including interfaces, functionality and algorithms and enables testing of SIPROTEC 5 protection devices in the cloud. The operating and parameterization program Reydisp is used for the configuration of the Reyrolle range of protection relays. The IEC 61850 system configurator is the manufacturer-independent solution for the interoperable engineering of IEC 61850 products and systems. It supports all devices with IEC 61850.
