*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.)
