High-end PLC performance in compact rack-free design

Designed to meet demanding machine automation requirements in a compact, modular, rack-free package, the Mitsubishi L series PLC from provides the performance, functions and capabilities of a system PLC but in a compact package.

Operating seamlessly with other Mitsubishi products such as GOT HMIs and inverter drives, L Series offers machine builder a cost-effective, integrated control platform for demanding applications like high speed bottling, labelling and packaging machines.

All models feature a basic 24 points of on board I/0, a dual-channel high speed counter, two axes of positioning, pulse catch and interrupt functions, Ethernet connectivity and built-in data logging.

Data logging function

The data logging function provides a simple means of collating OEE (overall equipment
efficiency) data, energy monitoring, sequencing and production traceability, with the
facility to store this data to an SD memory card using the integral memory card slot. The same memory card slot also makes it easy to back up or load the CPU programs and parameters. The backups can then be just as easily restored or used to program other
CPUs. The memory card can also be used to hold data captured with the data logging function.

The positioning function has a start time of just 30µs, with a maximum high-speed output of 200k pulses per second, and features such as S-curve acceleration and acceleration, meeting the needs of complex machine positioning applications.

The Ethernet communications port provides a simple interface to enterprise level, seamless peer-to- peer communications, and direct connectivity to HMIs. Logged data
can also be retrieved via this port using FTP commands.

9.5ns PER INSTRUCTION

The CPU has a basic operation processing speed of better than 9.5ns per instruction, making it suited to high speed machine applications. The base CPU can incorporate a 16-character by 4- line text display, providing convenient monitoring and easy access to diagnostic information both for the CPU and any connected I/O modules, without the need to connect a PC or software. Users can check the system status and make setting changes directly from the display.

The system can be expanded up to a total of 40 expansion modules, which include motion control modules, analogue I/O modules and temperature control modules. Mitsubishi Electric has developed a new motion module for the L Series that provides high -speed,
high precision control of up to sixteen axes per module over Mitsubishi’s SSCNET III servo
controller network. SSCNET is limited to Mitsubishi servos but maximises speed in this
configuration. The CPU can accommodate multiple motion modules and can consequently provide many axes of control, with capabilities including a cam
function, phase compensation, mark detection and 600 points of user-defined positioning data.
