11.4.3. Ethernet Information
xFace Gateway information block in Gateway tab allows the user to know much
information about gateway instrument as in the following;
Field bus: Ethernet
Firmware Version: Revision number of firmware
Firmware Date: Generated firmware date
Hardware Version: Revision number of main pcb board.
Serial Number: Instrument’s serial number.
Gateway Status: Follow the status whether the system is proper or not.
11.5. Modbus TCP/IP Data Structure
The Modbus slave address is defined in the Ethernet Address in Section 10.4.1. Functions
code ‘0x03’ and function code ‘0x10’ are supported. Make the Ethernet connection settings
in Section 10.2.
Modbus TCP/IP High-Low:
In two word registers, the data is stored to the registers in big-
endian format. Least significant word is stored to the highest register address; and most
significant word is stored to the lowest register address.
Modbus TCP/IP Low-High:
In two word registers, the data is stored to the registers in
little-endian format. Least significant word is stored to the lowest register address; and
most significant word is stored to the highest register address.
Write operations can only be done to the allowed registers. And they are indicated as W or
W/R. Do not try to write ‘only read’ registers indicated as R. The below Modbus table
identifies MX08 AD and MX08 IO instruments’ N-Bus address as [X].
Please find Modbus information in the web site of http://www.modbus.org
Examples:
Performing Read and Write operations according to hex system with the MX08 EN set to
address ‘0x01’. MBAP (Modbus Application Protocol) Header is not included to the below
Modbus TCP/IP application data units.
