The new L series PLC from Mitsubishi
Electric has been designed to
provide the functions and
capabilities necessary for today’s
demanding machine automation
requirements in a compact, modular,
rack-free package.

Bridging the gap between the
company’s FX compact PLC and its
iQ platform PAC, the modular
controller combines much of the
power of a Q series CPU, with the
ease of expansion and user-centric
design offered by the FX.

All the features and functions
needed for sophisticated automated
machines are built into the CPU as
standard, minimising hardware,
saving panel space and engineering
costs and ensuring flexibility.

Every L series CPU provides as
standard; 24 points of on board I/O,
a 2-channel high speed counter, 2-
axes of positioning, pulse catch and
interrupt functions, Ethernet
connectivity and built-in data logging.

The built-in positioning function
has a start time of just 30µs, with a
maximum high-speed output of 200k
pulses/sec, and features such as Scurve
acceleration and deceleration,
meeting the needs of complex
machine positioning applications.

The built-in 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 SD
memory card using the integral
memory card slot. The same slot also
makes it easy to back up or load the
CPU programs and parameters.

A built-in Ethernet communications
port provides a simple interface to
the enterprise level, seamless peer to
peer communications and direct
connectivity to devices such as HMIs.
