Data Base Exporter
The Database Exporter tool allows users to save Analog Data Logger and Digital event recorder points from the D400 to your local PC, using the WEB interface, in comma-separated values (CSV) format.
Automatic Record Retrieval
The Automated Record Retrieval Manager (ARRM) retrieves and stores record files from devices connected to the D400. ARRM uses the Distributed Network Protocol (DNP) and the IEC 61850 protocol to communicate with a variety of devices, and uses the Trivial File Transfer Protocol (TFTP) or MMS to transmit the files from the IED to the device over a Local Area Network (LAN) or serial connection.
You can also retrieve downloaded records from the D400 using any FTP/SCP/SFTP client as needed or on a scheduled basis.
ARRM supports a configurable interval for polling connected devices. This can be activated or deactivated through the runtime viewer display screen.
The connection status of the devices, in addition to the data retrieved from the IEDs can also be displayed or made available directly to the Tarigma Grid Enterprise Manager (GEM) software.
Parallel Redundancy Protocol
IEC 62439-3 (Edition 2), Parallel Redundancy Protocol
Substation LAN redundancy has been traditionally accomplished by reconfiguring the active network topology in case of failure. Regardless of the type of LAN architecture (tree, mesh, etc.), reconfiguring the active LAN requires time to switchover, during which the LAN is unavailable.
Parallel Redundancy Protocol is an IEC 62439-3 data communication network standard which is often used to overcome single network failure without affecting the data transmission. PRP is independent of the communication protocols and provides no packet loss (“zero recovery time”) availability by using connected nodes which transmit and receive over two independent network active paths. Under PRP, each network node has two Ethernet ports attached to two different local area networks, using standard bridges, and similar topology.
Existing D400 systems with 1 GHz or newer CPU can be upgraded via firmware in order to enable the Parallel Redundancy Protocol. The D400 can communicate simultaneously to devices connected to a common network, carrying mixed traffic: single LAN, legacy redundant or dual LAN, and PRP. This aids in implementing PRP in brown field installations, taking advantage of possible spare ports on existing managed switches LAN infrastructure. Additional LAN switches may be added as needed.
Analog Report Generation
In addition to the data logging capability within the D400, users can configure the D400 to record and generate online and offline reports from operational and non-operation analog data. While online reports can be retrieved instantly and are an extension of the data logger periodic reports, offline reports can be retrieved daily, weekly or monthly.
