No longer restricted to standalone applications, the new FX1N and FX2N micro PLCs from Mitsubishi Electric can now control as Masters AS-i and I/O link networks.
The age of the powerful micro PLC has arrived.
restricted to standalone applications, the new FX1N and FX2N
micro PLCs from Mitsubishi Electric can now control as Masters
AS-i and I/O link networks.
These enhanced communications
abilities now make the FX micro range of PLCs particularly suited
to distributed machine control applications, where the
requirement is for simple installation, reduced cabling cost, yet
still retaining high speed digital signal processing.
The new I/O
Link module, allows the FX1N and FX2N PLCs to master the I/O link
I/O Link is a simple Mitsubishi proprietary bit bus
network designed to make installation of digital networks simple
and cost effective.
As I/O Link is designed to specifically to
work with Mitsubishi PLCs, it means that there is no
configuration required, and no special programming.
All the user
has to do is to address the remote I/O as they would normally
program direct PLC I/O.
This simple to install yet powerful
network from Mitsubishi allows for 64 inputs and 64 outputs to be
distributed over distances up to 200 metres.
I/O link has a total
network refresh time for all 128 I/O of only 5.4 milli seconds.
The Actuator Sensor Interface (AS-i) compatible FX2N-32ASI-M
master module plugs directly into the FX1N or FX2N PLC as an
Each master can control up to 31 remote I/O
blocks, with each I/O block capable of connecting 4 digital
inputs and 4 digital outputs, giving a grand total of up 248
remotely located digital devices, such as sensors and actuators
controlled by one Master.
This control capability when added to
AS-iïs technology of being able to transmit communication and
power over its distinctive yellow profiled cables, ensures that:
installation is made as simple as possible, commissioning time of
field devices is greatly reduced, and there is no compromise on
These enhanced facilities add to the already
impressive communication options of the FX1N and FX2N, such as
the ability to be a slave on Profibus DP and DeviceNet networks.
It is also possible to use a separate Profibus DP bridge (in
place of a PLC) to be used with the standard FX0N/FX2N I/O and
analogue expansion modules., In addition to this breadth of
connectivity the FX1N and FX2N are already able to connect as a
slave station to the latest technology in open fieldbusses like
"CC-Link" and will soon be able to master this network
In conclusion it would be fair to say Mitsubishi's
Micro PLCs have really come of age.
