Hi,

Could someone explain how the plc firmware functions and what it does? Is there a relationship/interface between the firmware and the code?

Thanks.

This is a little simplistic, but the firmware is basically the operating system.
Firmware is usually revised/upgraded to support new instructions, or correct bugs.
