PROGRAMMING-SOFTWARE

POWERPRO 2 FOR LM

Standard Programming Language

PowerPro, the programming software for the system that complies with IEC61131-3 international standard, represents the latest industrial PLC programming trend. Six programming languages are available including LD, FBD, IL, ST, SFC and CFC.

Rich Function Blocks and Instructions

The system is provided with over 400 function blocks and many other instructions tailored according to needs of users. Common instructions include arithmetic operation, evaluation, Boolean, shift, selection, compare, data type conversion, addressing, call, strings and etc. Common function blocks include enhanced PID controller, signal generator, function manipulator, analogue processing, Modbus, ProfiBus, Ethernet, real-time clock, analogue potentiometer, watchdog, mono-phase and bi-phase counters, pulse output and etc.

Off-line Simulation

Off-line simulation allows programmers to simulate, test and debug their programming logic before actual ‘live’ implementation. Simulation features such as single-step, single cycle, breakpoint debugging and etc, conveniently facilitate the debugging process. All these make programming much easier and more convenient since it is not required to connect the PLC and download the programming codes to hardware devices.

Typical Applications

The LM Micro Series PLC can be utilized in many areas of applications such as the machine tool, punching machinery, printing machinery, spinning machinery, packaging machinery, plastic machinery, environmental protection equipments, central air conditioning, latex industry and various production lines.

Powerful CPU and Analogue Processing

The CPU calculation speed for a single boolean instruction is 0.37μs. It can simultaneously process dozens of analog channels and multiple loops of PID (proportional Integral Derivative) calculations.

Compact In Size

LM Micro Series PLC provides a tight integration of hardware and a complete range of functions within a compact size module.Diversity of ModulesAdopting a modular design, LM Micro Series PLC consist of a diversity of CPU modules and expansion modules to meet different applications and industries. A CPU module operating with a maximum of 7 expansion modules supports up to 152 digital I/O points or 56 analogue I/O channels.

Flexible System Configuration

LM Micro Series PLC utilizes a flexible system configuration with a large portfolio of expansion modules such as digital I/O, analogue I/O and other dedicated functional modules. Digital I/O modules available are 8-channel, 16-channel, and mix channels (4DI+4DO). Analogue I/O modules available are 4-channel input, 8-channel input, 4-channel thermocouple input, and 4-channel thermal resistance input that are used to receive current, voltage, thermocouple, thermal resistance and other types of signals. Analogue output module available are 2-channel.

Communications

The dedicated communication modules available are the PROFIBUS-DP slave modules and the Ethernet slave modules. Various communication interfaces such as RS-232, RS-485, PROFIBUS-DP and Ethernet are employed for the connection with other systems.

Easy Installation and Wiring

LM Micro Series PLC can be easily mounted on walls or standard DIN rails. The space-saving, patented WAGO wiring terminals are employed to ensure solid and firm wiring.

Data Loss Protection

Instructions and command data of the user are stored in a permanent storage area to prevent data loss caused by power loss or other failures.
