2.1 Product description
The C30 Controller System is part of the Universal Relay (UR) series of products. It is a microprocessor-based device
designed for power substation control and monitoring.
Diagnostic features include a sequence of records capable of storing 1024 time-tagged events. The internal clock used for
time-tagging can be synchronized with an IRIG-B signal, using the Simple Network Time Protocol (SNTP) over the Ethernet
port, or using the Precision Time Protocol (PTP). This precise time stamping allows the sequence of events to be determined
throughout the system. Events can also be programmed (via FlexLogic
that can be set to record the measured parameters before and after the event for viewing on a computer. These tools
significantly reduce troubleshooting time and simplify report generation in the event of a system fault.
Several options are available for communication. An RS232 port (USB port with the graphical front panel) 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, 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 (C30 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 C30 uses flash memory technology that allows field upgrading as new features are added. Firmware and software are
upgradable.
