  • Page 15: Product Description

    The Ethernet port supports IEC 61850, Modbus/TCP, TFTP, and PTP (according to IEEE Std. 1588-2008 or IEC 61588), and it allows access to the relay via any standard web browser (G30 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port. The Ethernet port also supports the Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option.
  • Page 16 PRODUCT DESCRIPTION CHAPTER 2: PRODUCT DESCRIPTION The G30 uses flash memory technology that allows field upgrading as new features are added. Firmware and software are upgradable. The following single-line diagrams illustrate the relay functionality using American National Standards Institute (ANSI) device numbers.

  • Page 19: Security

    The G30 supports password entry from a local or remote connection. Local access is defined as any access to settings or commands via the faceplate interface. This includes both keypad entry and the through the faceplate RS232 port. Remote access is defined as any access to settings or commands via any rear communications port.
