3. Menu settings for PROFIBUS-PA
(see Section 8.4 in the Installation and Operating Instructions)
The following settings need to be made for operation of the BM 70 A/P on a PROFIBUS-PA network. Note that the
service “set slave address” is not being supported. Therefore the address can only be set by way of the local display
and operator interface.
Function (Fct.) Input range Default value Description
3.3.5 BAUDRATE Select 31250 Bd. 31250 Bd. If Fct. 3.3.7 is set to ”PROFIBUS”, the baud rate is
fixed at 31250 Bd.
3.3.6 ADDRESS Input 0 ... 126 126 If Fct. 3.3.7 is set to ”PROFIBUS”, the default value
of the address is 126.
3.3.7 PROTOCOL Select HART
KROHNE/PC
PROFIBUS
PROFIBUS Selection of the communications protocol.
Set to PROFIBUS when delivered.
(only when appropriate hardware provided)
