The mechanics of the polling algorithm are essentially transparent to you.
This is because the communication modules handle this automatically.
However, the polling algorithm does lead to the following basic rules that
you should follow to optimize your Data Highway performance:
Number stations sequentially whenever possible.
Keep the number of high priority messages as low as possible.
Large numbers of high priority messages slow all traffic on the network.
In general, you should limit the number of high priority messages to less
than 1% of the total traffic on the Data Highway.
There are two checks used in Data Highway network message
transmission:
A 16-Bit Cyclic Redundancy Check (CRC) on a Data Highway Link
An 8-Bit Block Check Character (BCC) or a 16-Bit CRC on an
Asynchronous Link
Additionally, you can select a parity check (even parity only) on the
asynchronous link.
