mbusSlaveConfigBaud (Function)

Architecture:	NX32L
Firmware version:	1.94.00

This function is used to change the baud rate of a wired M-Bus slave.

Input:

handle : SYSHANDLE

A handle to the connection

baud : DINT (300,600,1200,2400,4800,9600,19200,38400)

The new baud rate to use.

pri_addr : INT default -1

The primary address for the slave to configure. Use -1 to use the secondary address instead.

sec_addr : STRING

The secondary address for the slave to configure. Used if the primary address is -1.

Returns: INT

1	- Success
0	- Not supported
-1	- Invalid handle
-4	- Invalid baud rate
-5	- Invalid interface type.
-6	- Invalid address
-9	- Communication error
-10	- Communication timeout
-11	- Invalid reply

Declaration:

FUNCTION mbusSlaveConfigBaud : INT;
VAR_INPUT
   handle   : SYSHANDLE;
   baud     : DINT;
   pri_addr : INT := -1;
   sec_addr : STRING;
END_VAR;

Example:

INCLUDE rtcu.inc

PROGRAM test;
VAR
   mb : SYSHANDLE;
   rc : INT;
END_VAR;

BEGIN
   ...
   // Open wired M-Bus interface @2400 baud
   rc := mbusOpen(handle := mb);
   ...
   // Change baud on device with primary address 11 to 9600 baud
   rc := mbusSlaveConfigBaud(handle:=mb, pri_addr:=11, baud:=9600);
   ...
   // Change speed to 9600 baud to be able to communicate with the device
   rc := mbusBaudSet(handle := mb, baud := 9600);
   ...
END;
END_PROGRAM;
