Chapter 9 – Interfaces
To use the serial interface as a data interface (described below), it must be set to the
protocol
transparent
or to
3964R
(see 10.2.5 „(S)erial Output“ on page 52).
The transmission rates 19200 and 38400 baud (standard) can be set. You can select
the following output protocols:
Monitor only
(service/configuration, see 10 „Configuration of the System via the
Service Interface“ on page 48)
transparent
(data, see 16.3 „Procedure transparent“ on page 88)
3964R
(for data, see 16.2 „Procedure 3964R“ on page 87)
You can configure the telegram contents for the protocols transparent and 3964R.
You can include the desired parameters from a list into the telegram (see 10.2.5
„(S)erial Output“ on page 52).
9.2.1 List of system values that can be output
A telegram consists of a maximum of 24 user bytes. The minimum update rate at
19,200 baud thus results from
Figure 21
Equation: Minimum update rate
Since this is a binary transfer, you can – when using the 3964R procedure – insert
additional (DLE) characters from this procedure. You can configure all multi-byte
variables so that either the high byte is output first or the low byte is output first. The
8-bit checksum is only output when using the transparent protocol and includes the
start character. You cannot remove the start character as well as the checksum (pro
-
tocol transparent) from the data block.
