BUEP03E Protocol8-14
8.7.3 Command Types
This section provides a detailed explanation of the BÜP03E commands
and their parameters and lists possible application examples. These ex-
amples should be regarded as an introduction to the BÜP03E Command
Language..
When using the commands, the user should NOT impose unnecessarily
high traffic loads on the system bus. High loads can be prevented by
skilful use of the commands in program loops and function modules. For
example, if a job is complex, the commands should be linked to each
other as only one R5REQ call is adequate for activation of the command
chain. The data should only be retrieved with the Data Copy command
when required, as there is no point in calling the data until it is available.
The data receive times in an ideal case are indicated in the table below. A
practical value would be 100 ms for 100 characters at a baud rate of
19200. The 100 characters to be received can therefore be retrieved
within 100 ms when the serial interface is operating at a baud rate of
19200.
Baud rate (bps) Time for one character Time for 100 characters
19200 0.50 ms 50 ms
9600 1.00 ms 100 ms
4800 2.00 ms 200 ms
2400 4.00 ms 400 ms
1200 8.00 ms 800 ms
600 16.00 ms 1600 ms
300 32.00 ms 3200 ms
110 90.90 ms 9090 ms
