4: Indicates that access is made via MELSECNET/H, Ethernet, CC-Link or
serial communication module.
(b) Communication with serial communication module or Ethernet interface
module
Time to make communication with the serial communication module or
Ethernet interface module.
Refer to the following manual for communication time with the
corresponding module.

(7) Common processing time
Common processing of the CPU module processed in the system.
The common processing times are the values in the following table.
Common processing time (ms)
The processing times in the above table assume that the constant scan function
is not used.
When the constant scan function is used, wait processing is performed for the
period of constant scan setting shortage.
