Communications System

SB Breaker Communication

All SB Circuit Breaker trip unit feature levels of communication:

Zone Selective Interlocking and ACCESS System open-protocol

communications. The SB-EC Trip Unit is fully equipped for direct

integration into ACCESS or compatible communication systems.

It does not require a MTA (Multiplexer/Translator for ACCESS

communications and Zone interlocking) or expansion plug (EP).

If zone selective interlocking alone is specified for a SB-EC or TL

Trip Unit, a MTZ (Multiplexer/Translator for Zone Interlocking) and

an EP are required.

If zone selective interlocking and full ACCESS communications

are specified for a TL Trip Unit, a MTA and an EP are required.

The MT (as in MTA and MTZ) is a minicomputer that collects data

from and transmits data to difference components integrated into

the ACCESS communications system. The MT can support up to

eight field devices. Multiple MT’s can be connected, although an

expansion plug may be required for each trip unit.

Siemens WinPM supervisory software (version 4.0 or later) delivers

a powerful energy management system providing sophisticated

monitoring capability to a host computer and other components in

the electrical distribution system at affordable cost. It also provides

process control, including peak demand, trend analysis, waveform

analysis, and harmonic calculations and displays. These functions

help pinpoint energy consumption, power quality issues, and the

energy cost of any process. Outages and potential outages can be

quickly diagnosed and plans can be generated for expansion and

preventative plant maintenance.

NOTE: Refer to Bulletin IPIM-2211A for additional information

on the MTA and Siemens WinPM software.

Communications is accomplished via EIA-485 twisted pair wire or

modem. It provides communications to a remote site and allows

access to multiple plants, WinPM uses a Microsoft Windows

dynamic data exchange (DDE) server that allows data exchange

to other Windows-based software such as spreadsheets and word

processors.

Protocol Converters are available form the Siemens ACCESS

group for connecting a variety of open and proprietary automation

protocols, including Profibus DP, LonWorks, Siemens S7 PLC, and

many other third-party PLCs and associated networks. The SB-EC

Trip Unit’s EIA-2342 communications port provides additional PC

communications for available trip unit data displays and trip unit

configuration via Siemens SBWIN software. Remote open/close

operation is also possible if a remote open/close relay is installed.

Expansion Plug

Factory wired when ACCESS communications or ZSI is ordered for the SB

breaker from the factory.

The EP is an electronic interface and isolation module required to

integrate a breaker into an ACCESS system. When required, one

expansion plug is used for each circuit breaker in the system and

is used to interface trip units to a MTZ or MTA. The expansion

plug is always necessary for zone interlocking or full ACCESS

communications for the TL Trip Unit. It is not required for ACCESS

communications with the SB-EC Trip Unit. However, an expansion

plug is required for zone interlocking with the SB-EC Trip Unit.

Expansion Plug Dimension Drawing

SB System Breakers

The following sections describe both types of SB trip units, the

standard Type ‘TL’ unit with rotary switches, and the SB Energy-

Comm (SB-EC) Trip Unit with keypad and display. Since the SB-EC

Trip Unit has integral communication capability, the MTA device

not

required to connect within an ACCESS system, however for

SB-EC Trip Units in a ZSI system, and MTZ or MTA is required.

The type EPSB expansion plug is factory wired to the SB breaker

trip unit’s rear connector and also located near and wired to the

SB breaker's secondary terminal block for fixed mount breakers or

sliding disconnects for drawout breakers. These connections are

factory wired when the SB breaker is ordered with the standard

switch based type “TL” trip unit for ACCESS communications or

for any trip unit with ZSI capability.

Installed ICCB SB breakers without communication capability may

be field upgraded for communication capability by Siemens Field
