MODBUS COMMANDS AND REGISTERS TABLE
The AirGate-GPRS accepts some Modbus commands that are sent to its Modbus’ own address, operating as a network
slave. Commands forwarded to other slaves (routing) will be sent in a transparent way. The following listed Modbus RTU
commands (functions) are implemented, and these are interpreted by AirGate-GPRS. For further information about each
command and the Modbus protocol in general, access the website
www.modbus.org .
SUPPORTED MODBUS COMMANDS
READ HOLDING REGISTERS – 03H
This command can be used to read a value of one or up to the maximum consecutive holding registers, as shown in the
“Table of Holding Registers”.
WRITE SINGLE REGISTER – 06H
This command can be used to write on a holding register, as shown in the “Table of Holding Registers”.
WRITE MULTIPLE REGISTERS – 16H
This command can be used to write in multiple holding registers, as shown in the “Table of Holding Registers”.
TABLE OF HOLDING REGISTERS
The specified addresses correspond to the low level physical addresses, where zero (0) corresponds to the address PLC
40001. The Minimum and Maximum columns have a range of valid values for each parameter. The R/W column
indicates if the parameter is for reading and writing (R/W) or if it is only reading ® The Mnemonic SuperView states what
the register mnemonic is for in the SuperView software.
