Using Function code 17 For Auto Detection of Slave Address
How does the Function code 17 detect slave address?


Can any one please specify how the function code 17 can be used to detect slave address? According to Modicon Specifications the response of the function code 17 contains Slave address and Slave ID in data field.

I am in confusion that What is Slave ID in that response. is it the slave address or some thing other?

Thanking you in advance.
