In industrial settings, a master device, like a PLC or SCADA system, controls and requests data from slave devices (e.g., sensors, meters, actuators). Modbus Poll acts as a "fake master," allowing engineers and developers to test, debug, and simulate communication with slave devices without needing the actual master hardware.

Modbus Poll operates as a Modbus master simulator. It is primarily used to replicate the polling behavior of Programmable Logic Controllers (PLCs) or Human-Machine Interfaces (HMIs). Key Features If you work in industrial automation, SCADA systems,
