12. bits of data sometimes referred to as integers are the most commonly used type of Modbus data and are supported by most Modbus hosts In the 4590 TSM implementation the Modbus word registers are used to transfer one of the following four formats e Word Data unsigned a scaled number from O to 65535 e Integer Data signed a scaled number form 32768 to 32767 e Coded Data Multiple choice configuration data chosen from a coded list e Packed Bit Data Registers form of 16 packed single bits The word and coded data registers contain all of the information needed to configure and read process data Any word register may be read with function code 03 or function code 04 These same registers may be written one at a time with function code 06 or multiple registers can be written with function code 16 4 1 1 Word data The word data unsigned is a whole number between O and 65 535 stored as a 16 bit binary number 4 1 2 Integer data Integer data signed is a scaled number from 32768 to 32767 4 1 3 Coded data Coded data responds to a look up table value Data written to these registers must be a valid table entry or the value is rejected For example within the 4590 TSM the units of a value are represented by the HART standard value look up table see Modbus register assignments Therefore if the Units value read from a HART device was 45 002D Hex the units would be Meters Functions and Data Formats Tank
