Point Map April 2, 2004 Systems Integration APOGEE Open Processor with Cummins/Onan Modbus Driver: PowerCommand System This document provides example point maps for common devices in a Cummins/Onan PowerCommand system: generator sets (gensets), Automatic Transfer Switch (ATSs), and feeder breakers. Communication with these devices is accomplished via the PowerCommand Digital MasterControl. Cummins/Onan Modbus registers use a 400,000 addressing scheme, which corresponds to Siemens Modbus registers in the 40,000 range. For example, Cummins/Onan register 400102 equals Siemens register 40102. Generator Set Point Maps Holding Integer Registers (Genset) Table 1. Holding Integer Registers (Genset) Point Map.
