HollySys LK511 module LK Programmable Logic Controller

HARDWARE ARCHITECTURE

The LK PLC consists of a set of hardware modules which includes the CPU, communication, and I/O modules that can be combined and configured on the backplane to satisfy a broad range of automation control applications.

CPU MODULES Communication CPU I/O Special Function I/O I/O Terminal Block 

 • This is the main controller of the whole control system. It is responsible for execution of the programmable logic, all data communications with the modules, the HMI, and the operator stations in operation level. 

 • Communications with the local modules are done via internal data bus supporting at normal or high speed baud rate. 

 • Communications with the expansion I/O modules are done via the PROFIBUS-DP fieldbus. 

 • Communications with the operator level are done via Industrial Ethernet. 

 • At the front panel of the CPU module, you will find the LED status indicator, operating mode switches, rotary switches for addressing, SD memory card and backup battery compartment. I/O MODULES 

 • Various digital and analog I/O modules available such as sink/source, AC/DC, transistor/triac/relay, current/voltage/RTD/thermocouple to meet different scenarios of applications. SPECIAL FUNCTION I/O MODULES 

 • Special purpose modules available such as frequency counters and sequence of events. (SOE) COMMUNICATION MODULES 

 • Provide system expansion and other third-party product communication. BACKPLANES I/O TERMINAL BLOCK 

 • Various popular communications are available such as PROFIBUS-DP, MODBUS, etc. 

 • Two main types are available, the local backplane and expansion backplane. 

 • Two variations are available, the backplanes with build-in I/O terminal points and the backplanes without I/O terminal but extended via cabling using I/O terminal blocks. (Launching Soon.) 

 • This is required for the backplanes without I/O terminal but extended via cabling. It provides the I/O terminal points to connect to the field devices. POWER SUPPLY MODULE 

 • Provides the power supply to the LK panel
