He initiated a . In the world of Modbus, a poll is a conversation: the master asks, and the slave answers. Most technicians were content with the surface-level readings of Holding Registers (the "4x" values that could be changed), but Elias went deeper. He targeted the Input Registers (0x04), the read-only memory where the hardware's rawest secrets lived.
The use of Modbus Poll Key Full offers several advantages in industrial automation settings:
