The LK210 series PLC was launched in 2006. It was China's first medium-to-large PLC, supporting single-rack redundancy. Two controllers are installed on the same local backplane and operate in a hot backup mode. The LK210 series PLC supports the Profibus bus protocol and communicates with I/O modules on the local backplane and expansion backplane via the Profibus bus.
