iQ Platform-compatible PACSafety CPU module,Safety Remote I/O module

Story

Integrated generic and safety control

The MELSEC iQ-R Series is equipped with a safety CPU that is

compliant with international safety standards, ISO 13849-1 PL e

and IEC 61508 SIL 3. The safety CPU can be installed directly

on the MELSEC iQ-R Series base rack and can execute both

safety and non-safety programs, enabling easy integration into

existing or new control systems.

Consolidated network topology

The safety CPU enables control of safety and non-safety

communications across the same CC-Link IE Field network

line. Wiring and space can be reduced as having multiple

network cables are no longer required resulting in lower

integration costs.

Highlights

• Complies with international safety standards

• Execute both safety and non-safety programs

• Integrated network communications

• Common engineering platform

• High-scalability safety remote I/Os available

Programming using GX Works3

The safety CPU can be programmed using GX Works3 enabling

machine makers to realize lower cost safety solutions as only one

programming software is required for the MELSEC iQ-R Series,

while utilizing its intuitive user interface and maintenance

features.

Safety CPU is compliant with ISO 13849-1 PL e and

IEC 61508 SIL 3 and is certified by TÜV Rheinland®*2.

Safety CPU can be installed directly on the

MELSEC iQ-R base rack realizing easy integration into

an existing or new control system. Also, compact remote

I/Os are available ideal for systems with limited space.

Establishing a safety communication is as easy as configuring a CC-Link IE Field network, which has the long-standing

reputation as a versatile gigabit network. The physical layer and data communications is based on Ethernet technology

and enables commercial cables, adapters, and hubs to be used*1. The safety communication also takes advantage of

highly flexible features offered by CC-Link IE Field network.

Safety

Integrated safety control offering a

total system solutionThe safety CPU module enables control of both generic and safety programs in the same

module and is easily programmed utilizing the intuitive features of GX Works3. Compliant

with internationally recognized safety standards, the safety CPU enables safety devices

such as safety light curtains, emergency switches, and door switches to be connected via

the CC-Link IE Field network without requiring a separate dedicated network line. The safety

CPU is easily programmed using GX Works3, and utilizes its intuitive features.

Integrated safety control enabling coordination with driving products

The safety CPU can be installed directly on the MELSEC iQ-R Series base rack, and is easily integrated into an existing or new

control system. Safety devices are connectable using the CC-Link IE Field Network with safety communication integrated into the

network protocol over a widely available industrial Ethernet topology. The safety CPU is compliant with ISO 13849-1 PL e and

IEC 61508 SIL 3 and is certified by TÜV Rheinland®. The MELSERVO-J4 Series servo amplifiers can be controlled through their

connectivity with the MELSEC iQ-R Series via CC-Link IE Field Network. When the safety CPU*1 is used with the simple motion

module (RD77GF), the MELSERVO-J4 Series servo amplifier can receive safety signal data from the safety CPU via CC-Link IE

Field Network. Additional wiring between the safety remote I/O and MR-D30 functional safety unit is unnecessary.

*1. Inter-modular synchronization function is not available with the safety CPU (R□SFCPU-SET).

MELSERVO-J4 Series servo amplifiers and motors

Combined with the MR-D30, the MELSERVO-J4 Series servo amplifiers and motors can perform safety operation compliant with

“Category 4/PL e” and “SIL 3”

• When the MR-J4-GF-RJ is used with the MR-D30, safety observation functions (STO, SS1, SS2, SOS, SLS, SBC, SSM) are

supported with easy setting of parameters*2

• Turning off the servo amplifier control circuit power supply is unnecessary, enabling shorter restart time and eliminating home

position return

• A magnetic contactor for preventing unexpected motor start is not required*3

*2. Use the MR-D30 with software version “A1” or later.

*3. Two magnetic contactors are not required when STO function is used, even though one magnetic contactor is used for preventing servo alarms and electrical shock in this diagram.

With GX Works3 generic and safety programs are included in the same project folder, eliminating the need to manage multiple

project folders. Various useful features of GX Works3 are also available for safety programs similar to other general programs.

Faster response times and handling of larger programs

Utilizing the high-performance capabilities of the MELSEC iQ-R Series and CC-Link IE Field Network, productivity is enhanced

as response times are even faster. Additionally, safety control program capacity has been increased by up to three times, to 40K

steps, enabling the control of more complex programs.

Automotive assembly line

Ensures safety on a large-scale production line and distributed system such as an automotive assembly line with multiple welding

robots operating. In systems with multiple stations and safety controllers, critical safety data is shared over the network which allows an

emergency stop in one station to safely stop the stations before and after within the production line. The safety CPU is connected using

the CC-Link IE Field Network with safety communication integrated into the network protocol. Also, the simple motion module supports

safety communication with the AC servo via CC-Link IE Field Network. General and safety devices, and drives can be connected

together with one CC-Link IE Field Network (up to 120 devices in total), realizing reduced wiring and highly scalable system lowering

overall cost.
