Mitsubishi MELSEC iQ-R PLC now offers an innovative safety option
which provides the performance and integrity of a separate safety PLC,
but without the extra cabinet space. The iQ-R combines responsiveness and continuity
with high process availability and reliability and is ideal for the most critical
to support applications - in addition to conventional process control.
To deliver safe and robust machines in applications
with low to high risk, machine builders and manufacturers have controls
that can meet specific safety requirements. The latest MELSEC
iQ-R series PLC meets these needs by providing a flexible, modular
to provide an all-in-one solution for process and safety control.
In addition to performing control tasks, the PLC can
combined safety and process safety functions. This offers the
ability to create applications that comply with ISO 13849-1 PL e- and
IEC 61508 SIL 3 standards, allowing users to rely on both the
performance as well as process integrity.
The combination of process and safety control in one
unit helps machine builders, integrators, process and production companies to
take advantage of this complete and scalable operating system. This is, in part, due to
optimize equipment footprint, reduce wiring needs
and reduce investment costs. These benefits are further enhanced
by the possibility of a common CC-Link IE Field Gigabit
Ethernet network to be used for both process and safety communication.
The complete control program is programmed with
using a single, intuitive platform, GX Works3. This makes it possible
to create and execute integrated process and safety programs through
a single CPU module, saving the time and cost of setting up two
individual operating systems are significantly reduced.
All these elements are built into an iQ-R and are
safety module results in a versatile solution whose application
can be easily modified or expanded. The controller is therefore suitable
for a wide range of sectors, from chemical process sites and
utilities to highly regulated pharmaceutical production.
