R Sim Modbus Simulator Download
modpoll is a command line based Modbus master simulator and test utility. modpoll is using the FieldTalk™ Modbus driver.
Modpoll binaries are available for the following systems:
- Windows PCs
- Linux PCs
- ARM based Linux boards like Raspberry Pi, BeagleBoard and others

Installation
Windows
Download archive into a folder and extract the zip archive. The modpoll.exe command must be run from a Command Prompt:
cd modpoll\win modpoll -h
Linux
Download archive into a folder. Then unpack the tarball:
tar xzf modpoll.tgz
The tarball contains multiple binaries for different CPU architectures. Add the version matching your system architecture to the path. Example for ARM platforms like Raspberry Pi:
export PATH=$PWD/modpoll/linux_arm-eabihf:$PATH
Then run modpoll:
modpoll -h
Usage
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 MODBUS/TCP protocol 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 (1-255 for serial, 0-255 for TCP, 1 is default)\n -r # Start reference (1-65536, 1 is default) -c # Number of values to read (1-125, 1 is default), optional for writ ing (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 -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
Usage Examples
To get help on usage run the following command:
modpoll -h
To retrieve continuously 10 Modbus holding registers starting from reference 500 of slave ID number 5 with Modbus RTU at 9600 baud, no parity on COM1 run:
modpoll -b 9600 -p none -m rtu -a 3 -r 500 -c 10 COM1
To retrieve once 5 floating point values starting from reference 100 with Modbus/TCP from slave device with IP 10.0.0.100:
modpoll -t4:float -r 100 -c 5 -1 10.0.0.100
To write the value 1234 to register 1201 using Modbus/TCP and FC 16 (Write Multiple Registers):
modpoll -r 1201 10.0.0.100 1234
To write the value 1234 to register 1201 using Modbus/TCP and FC 6 (Write Single Register):
modpoll -r 1201 -c 1 10.0.0.100 1234
