INTRODUCTION
GenComm was devised by Deep Sea Electronics Plc to provide a uniform standard for
communicating with any generating set control equipment. It allows all telemetry information
relevant to a generating set to be read from the control equipment, regardless of manufacturer or
specification.
GenComm uses the Modbus protocol, complete details of which can be found in the Modbus
Protocol Reference Guide PI-MBUS-300 Revision J and the Open Modbus/TCP Specification draft
2, both available from the Modicon web site at http://www.modicon.com
This manual describes the parts of GenComm utilised by the DSE 550, 555, 5210 and 5220 range
of controllers, and gives the information necessary to allow the integration of these modules into
larger schemes such as building management systems.
