Communications

Open-protocol communications allows all SB Trip Units to be inte-

grated into Siemens supervisory software (WinPM™ V4.0) and

other popular third party energy monitoring networks. Protocol

Converters are available from the Siemens ACCESS Group for

connection to a variety of open and proprietary automation proto-

cols, including Profibus DP, LonWorks, the Siemens S7 PLC, and

many other third party PLCs. Refer to Bulletin IPIM-2211A for

additional information. EIA-232 communications is also available

for local PC communication and trip unit configuration via Siemens

SBWin™ software.

No additional accessory devices are required for integration of

the SB-EC Trip Unit into the ACCESS™ Communication System.

A Multiplexer/Translator (Catalog No. MTZ) and Expansion Plug

communication components are always required for Zone Selec-

tive Interlocking and must be ordered separately. Refer to page

13-14 for additional information.

Remote Automatic Operation

Remote, automatic open and close operation of the breaker

is possible via the SB-EC Trip Unit’s EIA-485 or EIA-232 com-

munication ports or a hard-wire input. Remote operation using

a communication port requires a protocol converter or Siemens

WinPM™ V4.0 software for EIA-485 Networked Communica-

tions or SBWin™ software for EIA-232 PC Communications for

the following required accessories. The Shunt Trip and Remote

Open/Close Relay accessories are required for the remote open

function, and the Electrical Operator accessory is required in

addition for both remote open and close operations.

Remote, automatic operation via a hard-wire input uses the

following accessories with optional control voltages available.

Only the Shunt Trip Accessory is necessary for the remote open

function, and the Electrical Operator is additionally required for

both remote open and close operations.
