I use a modpoll program on Windows.

with modpoll -h i receive the following help information:

Usage: modpoll [OPTIONS] SERIALPORT|HOST [WRITEVALUES...] Arguments: SERIALPORT Serial port when using Modbus ASCII or Modbus RTU protocol COM1, COM2 ... on Windows /dev/ttyS0, /dev/ttyS1 ... on Linux HOST Host name or dotted IP address when using MDBUS/TCP protocol WRITEVALUES List of values to be written. If none specified (default) modpoll reads data. General options: -m ascii Modbus ASCII protocol -m rtu Modbus RTU protocol (default if SERIALPORT contains \ or COM) -m tcp MODBUS/TCP protocol (default otherwise) -m udp MODBUS UDP -m enc Encapsulated Modbus RTU over TCP -a # Slave address (1-247 for serial, 0-255 for TCP, 1 is default) -r # Start reference (1-65536, 100 is default) -c # Number of values to read (1-125, 1 is default), optional for writing (use -c 1 to force FC5 or FC6) -t 0 Discrete output (coil) data type -t 1 Discrete input data type -t 3 16-bit input register data type -t 3:hex 16-bit input register data type with hex display -t 3:int 32-bit integer data type in input register table -t 3:mod 32-bit module 10000 data type in input register table -t 3:float 32-bit float data type in input register table -t 4 16-bit output (holding) register data type (default) -t 4:hex 16-bit output (holding) register data type with hex display -t 4:int 32-bit integer data type in output (holding) register table -t 4:mod 32-bit module 10000 type in output (holding) register table -t 4:float 32-bit float data type in output (holding) register table -i Slave operates on big-endian 32-bit integers -f Slave operates on big-endian 32-bit floats -e Use Daniel/Enron single register 32-bit mode (implies -i and -f) -0 First reference is 0 (PDU addressing) instead 1 -1 Poll only once only, otherwise every poll rate interval -l # Poll rate in ms, (1000 is default) -o # Time-out in seconds (0.01 - 10.0, 1.0 s is default) Options for MODBUS/TCP, UDP and RTU over TCP: -p # IP protocol port number (502 is default) Options for Modbus ASCII and Modbus RTU: -b # Baudrate (e.g. 9600, 19200, ...) (19200 is default) -d # Databits (7 or 8 for ASCII protocol, 8 for RTU) -s # Stopbits (1 or 2, 1 is default) -p none No parity -p even Even parity (default) -p odd Odd parity -4 # RS-485 mode, RTS on while transmitting and another # ms after

if i use the following command:

modpoll.exe -l 5000 -t 4 -p 502 -m enc -a 247 -r 769 -c 124 192.168.178.88

i receive data from the modbus device like following

Protocol configuration: Encapsulated RTU over TCP, FC3 Slave configuration...: address = 247, start reference = 769, count = 124 Communication.........: RS485-TO-ETH, port 502, t/o 1.00 s, poll rate 5000 ms Data type.............: 16-bit register, output (holding) register table

-- Polling slave... (Ctrl-C to stop)

-- Polling slave... (Ctrl-C to stop)

can someone explain me how the config file of modpoll must look so that I get data?
