KC868-A and ds18b20

[kulibin]

I want to connect the temperature sensors ds18b20.
How many sensors can be connected to the S1 conector?
 Do I need to connect an additional resistor to the 4,7K?

i don't know which board model you are asking?
maybe you are using KC868-A8, one 1-wire port only use by one sensor. it have pull up resistor on PCB already.
