Mitsubishi Electronics AJ71QE71N-B2, AJ71QE71N-B5T, A1SJ71E71N-B5T manual New Features, Unit ms

[New Features]

(1)Increased range of connections to match the system configuration.

With the introduction of the 10BASE-T connection Ethernet interface module (hereinafter, Ethernet module), the PLC and personal computer can now be connected with 10BASE5, 10BASE2, or 10BASE-T.

(2)High-speed internal processing

With the Ethernet module's faster internal processing, the PLC responds much faster when exchanging data with an external device.

The following table shows the minimum transmission delay time (reference value) on the PLC side when using each communication function.

(This is based on the PLC CPU scan time of 10ms.)

Communication function	Outline of communication process	QnA Series		A Series
		New	Old	New	Old
		product	product	product	product
Using read/write data in	UDP/IP communication￿Communication with binary	27	43	40	56
the PLC CPU	code data￿Reading of D0 to D99
Using fixed buffers	TCP/IP communication￿Communication with binary	65	118	65	118
