QUESTION:
Does the maximum transfer rate of the S7-400
PtP CPs depend on the MLFB?
ANSWER:
In some S7-400 PtP CPs the maximum transfer
rate does depend on the MLFB of the CP.
The following table lists the maximum transfer rates of the
S7-400 PtP CPs.

Table 1: Transfer rates of S7-400 PtP CPs
(1) With 20 mA TTY interface only 300 -19200 bit/s is
possible
(2) Sum baud rate max. 115200 bit/s
Note:
With CP441-2 (6ES7 441-2AA03-0AE0) the maximum permissible transfer
rate of both interfaces is in sum 115200 bit/s.
