CPU Bus Unit Service Processing Time (Local Node)
The processing time will be as follows, depending on the CPU processing
mode settings at the CPU Unit:
For details, refer to the CPU Unit operation manual.
Transmission Processing Time
Number of words sent x 0.002 + 0.550 ms
Transmission Delay
The transmission delay time will be as given below, depending on the baud
rate set for the Ethernet Unit. (There may be additional delays depending on
devices, such as hubs, in the network configuration.)
Reception Processing Time

0.003 + 0.704 ms
CPU Bus Unit Service Cycle (Remote Node)
The processing time will be as follows, depending on the CPU processing
mode settings at the CPU Unit.
For details, refer to the CPU Unit operation manual.
CPU execution mode Processing time considerations
Normal Mode Set time for peripheral servicing
