Enhanced information communication by networking is the essential requirement in the automation industry. The MELSEC-Q Series provides an open and seamless network environment integrating the following different level of automation networks: CC-Link IE; high-speed and large capacity Ethernet-based integrated open network that connects shop floor and IT system as the core of e-F@ctory, CC-Link; SEMI certified global standard network originating from Japan and Asia, CC-Link/LT; wire-saving sensor level network inherited CC-Link design concept, and AnyWire; sensor level distributed control network.

Network Configurations

Seamless communication

CC-Link IE Control is a high-reliability distributed control network designed to handle very large data communications (128K word) over a high-speed (1 Gbps) dual loop optical cable topology.

*: Compatible modules: QJ71GP21-SX, QJ71GP21S-SX

CC-Link IE Field is an all-round versatile gigabit Ethernet based network integrating controller, I/O control, safety control, and motion control in a flexible wiring topology supporting star, ring, and line configurations.

*: Compatible modules: QJ71GF11-T2, QS0J71GF11-T2 (safety control), QD77GF4, QD77GF8, QD77GF16 (motion control)

CC-Link IE Field Network Basic realizes easier network integration, as its cyclic communications stack is software-based, without requiring a dedicated ASIC helping to reduce implementation costs for device partners. CC-Link IE Field Network Basic, which is a part of CC-Link IE, realizes easier connection of Ethernet devices.

*: Compatible modules: QnUDVCPU, QnUDPVCPU

CC-Link is a high-speed and high-reliable deterministic I/O control network which realizes reduced wiring whilst offering multi-vendor compatible products. This open field network is a global standard originating from Japan and Asia.

*: Compatible module: QJ61BT11N

CC-Link Safety is a safety field network that prevents risks on the shop floor.
This realizes a highly-reliable and a high-speed communication with less wiring.

*: Compatible modules: QS0J61BT12

CC-Link/LT is a wire-saving sensor level network which is designed for use in panels between simple discrete devices. Its wiring system is based on reducing incorrect wiring and is based on CC-Link realizing high-speed and robust noise resistance features.

*: Compatible module: QJ61CL12

AnyWireASLINK makes it possible to centrally monitor (visibility) the state of all sensors from the programmable controller, by that improving productivity and reducing operation steps.

*: Modules supporting AnyWireASLINK: QJ51AW12AL, NZ2AW1C2AL

SSCNET Ⅲ/H is a dedicated high-speed, high-performance, and highly reliable servo system control network which offers flexible long distance wiring capabilities based on optical fiber cable topology.
