A Appendix: Modbus Interface WirelessHART Fieldgate SWG70 A Appendix: Modbus Interface A.1 Introduction A.1.1 Modbus protocol Modbus is a quasi-industrial standard developed some years ago by Gould-Modicon and provides a messaging service that may run on a variety of physical layers. For Fieldgate SWG70 there are two possibilities for connecting Modbus: • Modbus RTU (also known as Serial) can be connected point-to-point to the RS-485C interface as described in Chapter 5.4.
WirelessHART Fieldgate SWG70 A Appendix: Modbus Interface A.1.2 Modbus in Fieldgate Fieldgate SWG70 is equipped with both a Modbus serial and Ethernet interface. As a result, it can be operated in one of the following roles: • Modbus Serial Slave • Modbus TCP Slave A serial or TCP slave can be accessed by one Modbus master only. Establishing communication As a TCP slave, Fieldgate SWG70 will normally communicate with the master via Port 502.

WirelessHART Fieldgate SWG70 A Appendix: Modbus Interface A.1.3 Data types Fieldgate SWG70 supports three different data types, which are interpreted and stored as described below: • Floating point, Unsigned Integer16, Unsigned Integer8 Floating point Value range (±) 1.175 * 10-38 to 3.403 * 1038 Byte Structure 31 Sign Unsigned16 0 23 Exponent (8 bit) Fraction (23 bit) Storage Float Modbus Register 1 15 0 Swapped Float 31 16 Modbus Register 2 31 16 15 0 Value range 0 to 65.
A Appendix: Modbus Interface WirelessHART Fieldgate SWG70 A.2 Rules for mapping A.2.1 Automatic mapping of analog devices (HART CMD3) Each HART device is mapped into 12 consecutive Modbus input registers. The order of HART device mapping starting from register 13 is the same as the order of the sub-device identity summary (returned by HART CMD84). For example, the HART device with the sub-device index=1 is mapped starting at register 13.
WirelessHART Fieldgate SWG70 A Appendix: Modbus Interface A.2.2 Digital input/output devices There is no automatic mapping of the Input Status registers: the user must generate the mapping table either semi-automatically or manually.
A Appendix: Modbus Interface WirelessHART Fieldgate SWG70 A.3 Mapping formats A.3.1 Dynamic process variables For each HART device, the 5 possible Command 3 floating-point dynamic variables are sequentially mapped (units code values are not mapped). If a device does not support a specific dynamic value, a "NaN" (Not a Number) floating-point value is returned (namely, 0x7F, 0xA0, 0x00, 0x00).
WirelessHART Fieldgate SWG70 A Appendix: Modbus Interface A.3.3 HART CMD48 Read Additional Status Information Command 48 returns device status information not included in the response code or device status byte of Command 3. All field devices support at least bytes 0 ... 8. If a field device supports more than one analog channel, then bytes 9 ... 13 will be supported as well.
A Appendix: Modbus Interface WirelessHART Fieldgate SWG70 A.3.4 Read Discrete Inputs HART Specification 285 describes the requirements for discrete and hybrid field devices. A discrete device will return discrete values only. A hybrid device may return both analog and discrete values. Discrete inputs are read by means of HART Command 64,386, which returns a block of discrete variables (values and status). The length of the data string depends upon the device polled.
WirelessHART Fieldgate SWG70 B Appendix: CSV File Formats B Appendix: CSV File Formats B.1 Structure of CSV Files When creating or editing CSV files for import into Fieldgate SWG70, the following rules apply: • Use a semicolon ";" as separator for the values in the CSV file. If a value already contains a semicolon you must put the value into quote signs. If the value already contains quote signs, put the entire value into quote signs and replace the original quote signs with double quote signs.
B Appendix: CSV File Formats Information Codes WirelessHART Fieldgate SWG70 Information Code Value Description 0 (HART Status) 0 Device Status 1 Extended Device Status 2 Device Status & Extended Device Status 1 (CMD 48 Status) 2 (Device Variable) 0 ... 12 CMD 48 status word to be mapped 0 maps CMD 48 bytes 0&1 1 maps CMD 48 bytes 2&3 ... and so on 12 maps CMD 48 byte 24 only 0 ...
