Communications cycle time = 2 (see note) + 0.11 x TB + 0.6 ms
TB depends on the baud range as follows:
500 KB/s: 2, 250 KB/s: 4, 125 KB/s: 8
Note
The communications cycle time when remote I/O communications are
stopped is 2 ms.

TB depends on the baud range as follows:

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.
