Communications cycle time = (communications cycle time for only remote I/O

TB depends on the baud range as follows:
500 KB/s: 2, 250 KB/s: 4, 125 KB/s: 8
Note
The above calculations for the message communications times are only for
use as guidelines. They do not produce maximum values. The message com-
munications time depends on the frequency of messages, the load on the
remote node, the communications cycle time, etc. If network traffic is concen-
trated on one Master Unit, long times will be required that those produced by
the above calculations. Be sure to consider this when designing the system.
