PRODUCT DESCRIPTION
Several options are available for communication. A faceplate RS232 port can be used to connect to a computer for the
programming of settings and the monitoring of actual values. The rear RS485 port allows independent access by operating
and engineering staff. It can be connected to system computers with baud rates up to 115.2 kbps. All serial ports use the
Modbus RTU protocol. The IEC 60870-5-103 protocol is supported on the RS485 interface. IEC 60870-5-103, DNP, and
Modbus cannot be enabled simultaneously on this interface. Also only one of the DNP, IEC 60870-5-103, and IEC 60870-5-
104 protocols can be enabled at any time on the relay. When the IEC 60870-5-103 protocol is chosen, the RS485 port has a
fixed even parity and the baud rate can be either 9.6 kbps or 19.2 kbps. The 100Base-FX or 100Base-TX Ethernet interface
provides fast, reliable communications in noisy environments. The Ethernet port supports IEC 61850, IEC 61850-90-5,
2
Modbus/TCP, TFTP, and PTP (according to IEEE Std. 1588-2008 or IEC 61588), and allows access to the relay via any
standard web browser (D60 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.
Secure Routable GOOSE (R-GOOSE) is supported with software options.
Settings and actual values can be accessed from the front panel or EnerVista software.
The D60 uses flash memory technology that allows field upgrading as new features are added. Firmware and software are
upgradable.
The following single-line diagram illustrates the relay functionality using American National Standards Institute (ANSI)
