45 4000 Modbus Implementation 9 Modbus Implementation 9.1 Introductio n This protocol guide explains the operation of the Modbus protocol as described in the following Modicon document: PI-MBUS-300 Rev B (1 985) implemented in the V arec Model 4000 Advanced Technology Transmitter (ATT).
Modbus Implementation Tank Gauge Transmitter 46 Installation and Operations Manual Table 9-1: Modbus Functions Note! Exception: Because the A TT does not di stinguish between inputs and outputs, function codes 01 and 02 as they apply to bits, and function codes 03 and 04 as they apply to nu meric values refer to th e same data registers.
47 4000 Modbus Implementation 9.4 Functions and Data F or mats The Modbus data in the ATT is arranged in integ er registers, floating point registers, and s tatus bits. The assignments for these registers are found at the end of this appendix. Function codes 03, 04, 06, and 16 are used with integer registers.
Modbus Implementation Tank Gauge Transmitter 48 Installation and Operations Manual Note! In all of the following communication examples, the erro r ch eck value is dependent upon the mode of transmission. 9.5.1 Integ er Dat a The integer data is a whole number between 0 and the maximum Modbus inte ger (inclusive).
49 4000 Modbus Implementation 9.5.2 Integer Dat a • Hexadeci mal representation • 4124Decimal equivalent: 16,676 The data returned for da ta address 56 is 16,676 (4124 Hex). This value must be scaled using the following formula to give it meaning.
Modbus Implementation Tank Gauge Transmitter 50 Installation and Operations Manual 9.5.4 Coded Da t a Coded data represents a table l ook-up valu e. Data written to these registers must be a valid table entry. Invalid data may cause a Configuration Error to occur.
51 4000 Modbus Implementation 9.6 Floating-P oint Re gisters Although not part of the Modbus protocol specification, fl oating poi nt numbers have been implemented using the IEEE 754 standard.
Modbus Implementation Tank Gauge Transmitter 52 Installation and Operations Manual 9.6.4 The One 32-bit Reg ister Format Function code 65 (41 Hex) is used to read floating-point registers in this format. An example of a floating-point register read is s hown below with the a temperatur e of 100.
53 4000 Modbus Implementation 9.7 Sta tus Bits In the ATT implementation, status bits contain alarms, commands, and status information. The state of a Modbus status bit is defined as either ON (true) or OFF (false). The ON state is represe nted by a "1".
Modbus Implementation Tank Gauge Transmitter 54 Installation and Operations Manual 9.9 Data Out of Range When integer data calculated by the ATT is outside the minimum or maximum scale points or is ot herwise out of range, the value returned is that of the maximum Modbus intege r + 1.
