G4 Multi Channel Weighing Instrument. PM/DT/HE Technical Manual

Technical ManualGeneral registersThe G4 instrument has a number of Modicon 'Holding Registers' (registers 4XXXX ... ).The Modbus function 03 'Read Holding Registers' should be used to read theseregisters and the Modbus function 05 'Preset Single Register' or 16 'Preset MultipleRegisters' should be used to write to the registers.See section ‘Data representation’ for a description of the different data formats used.Hint: To find out which of the float formats that should be used, readthe ‘Instrument type’ register (44000), which equals ‘4001’ for the instrument.Data type:IntegerData type: float(2 reg./value)Explanation40001 (1 reg) 44000 Instrument type R40002 (1 reg) 44002 Standard program major version R40003 (1 reg) 44004 Standard program minor version R40004 (1 reg) 44006 Special program major version R40005 (1 reg) 44008 Special program minor version R40006 (3 reg) 44010 Serial number RR/W40030 (1 reg) 44030 Command error R40031 (1 reg) 44032 Instrument state R40032 (1 reg) 44034 Instrument error R40033 (1 reg) 44036 Instrument status R40034 (1 reg) 44038 Scale 1: Error code R40035 (1 reg) 44040 Scale 1: Status R40036 (3 reg) 44042 Scale 1: Gross weight R40039 (3 reg) 44044 Scale 1: Net weight R40042 (3 reg) 44046 Scale 1: Flow rate R40045 (3 reg) 44048 Scale 1: Input signal (mV/V) R40048 (1 reg) 44050 Scale 2: Error code R40049 (1 reg) 44052 Scale 2: Status R40050 (3 reg) 44054 Scale 2: Gross weight R40053 (3 reg) 44056 Scale 2: Net weight R40056 (3 reg) 44058 Scale 2: Flow rate R40059 (3 reg) 44060 Scale 2: Input signal (mV/V) R6-4
