2 PRODUCT DESCRIPTION 2.1INTRODUCTION
The C30 Controller System 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 deter-
mined throughout the system. Events can also be programmed (via FlexLogic™ equations) to trigger oscillography data
capture which may be set to record the measured parameters before and after the event for viewing on a personal com-
puter (PC). These tools significantly reduce troubleshooting time and simplify report generation in the event of a system
fault.
Several options are available for communication. A faceplate RS232 port can be used to connect to a computer for the pro-
gramming of settings and the monitoring of actual values. The RS232 port has a fixed baud rate of 19.2 kbps. 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 100Base-FX or 100Base-T Ethernet inter-
face provides fast, reliable communications in noisy environments. The Ethernet port supports IEC 61850, Modbus/TCP,
and TFTP protocols, PTP (according to IEEE Std. 1588-2008 or IEC 61588), and allows access to the relay via any stan-
dard web browser (C30 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port, and DNP 3.0 and
IEC 60870-5-104 cannot be enabled at the same time. The Ethernet port also supports the Parallel Redundancy Protocol
(PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option.
Settings and actual values can be accessed from the front panel or EnerVista software.
The C30 IEDs use flash memory technology which allows field upgrading as new features are added.

The following security features are available:
• Password security — Basic security present in the default offering of the product
• EnerVista security — Role-based access to various EnerVista software screens and configuration elements. The fea-
ture is available in the default offering of the product and only in the EnerVista software.
• CyberSentry security — Advanced security options available as a software option. When purchased, the options are
automatically enabled, and the default Password security and EnerVista security are disabled.
Changing the password, or any other setting, does not take the relay out of service. The relay is taken out of service when
a settings file is written to it.
