[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.

*1. Indicates the communication interface for the corresponding unit. (!: Available)
(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.)
