Support EZSocket
It is possible to configure the communication setting by the same screen as useful GX Works (GX Developer).

Support L series/FX Ethernet/Stand-Alone Motion
Q170MCPU Support promptly new L series and FX series Ethernet. Support Q170MCPU of Stand-Alone Motion.

Equipped with "Q4E protocol" that controls packet gap
DeviceXPlorer doesn't happen the mismatch of response message and required message, because the Sequence number is embedded.
Q4E Protocol

Batch access function.
The more than one PLC register can be collectively read and written as separator string(slash "/") of a single tag. For example, when you add a OPCItem as "Device1.D0/D1000/ZR200/M0" , you can read "10351,23045,0,0".

Communication with random access buffer
Communicating shared memory of Ethernet unit by random access buffer, You can exchange datas high-speed , it doesn't depend on PLC's scan time.

Direct access to intelligent function module
Buffer memory"G" can only be accessed by groups for which the intelligent function module access is enabled. For example , When you select "QD75" and access to "G800", you can get "Current feed value".

MELSECNET transient transfer
You can access to other CPU on MELSEC/H and CC-Link/IE via the Ethernet unit. You can construct flexible system configuration , but the communication performance is lower.
Transient Communication

Support multi CPU
You can access the device memory of the CPU among two or more CPU installed on Q bus. Because the transfer function between CPUs side is not used, the system construction of high throughput is possible.

Support a redundant system(QnPRHCPU)
It is possible to access CPU by specifying control system or standby system, system A or system B. By combining with the redundant function of the DeviceXPlorer, it is possible to correspond to the redundant system that automatically switches the line when the communication abnormality is generated.
