(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.)
