Table 1‑1 M‑3311A Device Functions

The relay provides storage of time-tagged target

information for the 8 most recent trip events. Also

included are self-test, self-calibration and diagnostic

capabilities. The M-3911A Target Module LEDs are

used to provide a detailed visual indication of function

operation for the most recent event.

The M-3311A retains up to 311 cycles of oscillograph

waveform data assignable to up to 24 events with

selectable post-trigger delay. This data can be

downloaded and analyzed using the M-3801D

IPSplot

PLUS

Oscillograph Analysis Software.

The unit is powered from a wide range switch mode

power supply. An optional redundant power supply

is available for units without the Expanded I/O. When

expanded I/O option is selected, the unit includes the

second power supply.

The M-3311A includes self-test, auto calibration, and

diagnostic capabilities, in addition to IRIG-B time-

sync capability for accurate time-tagging of events.

Communication Ports

The M-3311A includes three physical communication

ports. If the optional RJ45 Ethernet port is

purchased, then COM2 is not available:

• COM1, located on the relay front panel, is

a standard 9-pin RS-232 DTE-configured

port. COM1 is used to locally set and

interrogate the relay using a portable

computer.

• COM2, located on the rear of the relay, is

a standard 9-pin RS-232 DTE-configured

port. When the optional RJ45 Ethernet

Port is enabled, COM2 port is disabled for

communications. The demodulated IRIG-B

may still be used via the COM2 Port when

ethernet is enabled.
The RJ45 Ethernet port uses a 10Base-T

type connection that accepts an RJ45

connector using CAT5 twisted pair cable.

The Ethernet port can support MODBUS

over TCP/IP, BECO2200 over TCP/IP,

DNP 3.0 or IEC 61850. The IP address

can be obtained automatically when using

the DHCP protocol if enabled, or a static

IP address can be manually entered,

using the HMI.

• COM3, located on the rear terminal block

of the relay, is an RS-485 communications

port.

The relay may be remotely set and interrogated

utilizing either a hard-wired RS-232 serial connection

or modem (COM2 when activated as RS-232, or

COM3), or when purchased, the ethernet connection

(RJ45 activated).

Detailed information regarding the use of the relay

communications ports is provided in

Appendix B,

Communications

, as well as Chapter 3,

IPScom

The system may be remotely set and interrogated

utilizing either a hard-wired RS-232 serial connection

or modem (COM2 when activated as RS-232, or

COM3), or when purchased, the ethernet connection

(RJ45 activated).
