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 or via the SNTP protocol over the Ethernet port. This precise time
stamping allows the sequence of events to be determined 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 computer (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 Ethernet interface provides
fast, reliable communications in noisy environments. The Ethernet port supports IEC 61850, Modbus/TCP, and TFTP proto-
cols, PTP (according to IEEE Std. 1588-2008 or IEC 61588), and 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, and DNP 3.0 and IEC 60870-5-104
cannot be enabled at the same time.
The C30 IEDs use flash memory technology which allows field upgrading as new features are added.

a) OVERVIEW
The C30 is available as a 19-inch rack horizontal mount or reduced-size (¾) vertical unit and consists of the following mod-
ules: power supply, CPU, CT/VT, digital input and output, transducer input and output, and inter-relay communications.
Each of these modules can be supplied in a number of configurations specified at the time of ordering. The information
required to completely specify the relay is provided in the following tables (see chapter 3 for full details of relay modules).
Order codes are subject to change without notice. See the GE Multilin ordering page at
