ASCII protocol same of Modbus protocol?

Answer:
Ascii is not a protocol - it describes a computer system's character set. Communication with a Modbus PLC requires an understanding of how to communicate and the protocol (set of rules) does describe this.

Ascii is a set of values describing the Latin codepage set that can represent certain characters in data. There are no communications "rules" with Ascii, just a data representation.
