Hi, I've no experience in getting the info from more than one sensor, but I've found some other approach to the DS18B20.
Seems that:

Code:
Temp   VAR WORD        
ID        VAR BYTE[8]       '64 bit memory array

OWOUT Pin, 1, [$33]         'This read the internal eeprom of the sensor
OWIN Pin, 0,[STR ID\8]      'Save the result into a 8 byte array

SELECT CASE ID[0]
	CASE $28
		'a DS18B20 has been found
		
	CASE $10
		'a DS18S20 has been found
		
END SELECT

OWOUT Pin, 1, [$CC, $44]                        ' Jump the ROM and convert
PAUSE 900                                       ' Give enough time for conversion (you could reduce it using 10 bit resolution)
OWOUT Pin, 1, [$CC, $BE]' Jump the ROM and read
OWIN  Pin, 2, [Temp.Lowbyte, Temp.Highbyte] ' Read 2 bytes
As said I've not experience in using more than one of those sensor, but probably there is a way to choose wich one using the data of the internal EEPROM.
If you get some result, please post your experience for future use.
