Very nice project! Using it very often.

Very useful Modbus simulator. Supports multiple IP addresses (slaves) and no need to setup or specify what HR or IR the simulator will answer on. In the latest version it is possible to log traffic and even get a decode of the messages in the log.

Good tool but nobody answers when questions are asked about it.

Very helpful to write unit tests of my APIs that use libmodbus. I wish we could change the endianness of the exchanged registers and bytes in a future version (ab-cd, cd-ab, ba-dc, dc- ba). The endianness of float data (badc, with libmodbus I use modbus_get_float_badc to parse correctly a float sent by the simulator) is not consistant with the one used for longs (this is how I reconstruct an unsigned 32-bit long integer : (regValues[0] << 16) + regValues[1]; => so it's ab - cd)

Great tool for emulate single/multiple Modbus Slaves. Complete set of options. Essential for office emulation test. Good job developer!
