ModbusBB
Modbus TCP/RTU/ASCII master & slave simulator for Windows, GUI+CLI
ModbusBB is the all-in-one Modbus toolkit for Windows: a fast Modbus master, a full slave simulator and a scriptable command-line tool in one app. Built for automation, SCADA and energy engineers who commission and troubleshoot PLCs, meters, inverters, drives and gateways.
Poll many devices at once over Modbus TCP, RTU, ASCII, RTU-over-TCP or UDP, each with its own tabs. See every byte in the raw TX/RX traffic monitor, decode Float32/64, Int32/64 and strings in any byte order with scaling and units, and run FC43/14 device ID, FC08, FC17, FC22 and FC23.
