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.

What is the Modbus communication protocol about?
The Modbus communication protocol is a simple and robust communication protocol to connect industrial electronic devices. It is easy to deploy and maintain.
What is the meaning of modbus?
Modbus is an industrial communications protocol. If you are referring to the word Modbus, I have not read it but suppose it comes from (MOD)icon (BUS).
What is the meaning of the protocol acronyms ASCII?
ASCII- American Standard Code for Information Interchange
What is profibus?
Modbus is a industrial communications protocol designed by Modicon in 1979 widely used in industry, while Profibus is a field bus standard developed by various companies (among these Siemens) in the late 80s. Modbus is the protocol that defines how messages are going to be transferred and Profibus defines the standard (set of protocols) that rule the communication system. As you can see they are not exactly the same. However, both are extensively used in the manufacturing industry these days.
What is BACnet protocol or Modbus protocol. Does this all types of protocols will manged by any central body?
BACnet is an building automation and control networking protocol. It was developed by ASHRAE. BACnet was designed specifically to meet the communication needs of building automation and control systems. Typical applications include: heating, ventilating, and air-conditioning control, lighting control, access control, and fire detection systems. BACnet International has reached an agreement to establish a test lab for BACnet products at SoftDEL systems www.softdel.com. Modbus is a data transfer protocol used mainly in the building and industrial automation industry. It was one the first open protocols and consequently an overwhelming number of vendors implemented Modbus interfaces. Modbus can only carry scalar data. For more information on these articles, free Modbus software tools and a free download of a BACnet explorer try www.chipkin.com. We have converters for Modbus, Bacnet, Lonworks, Metasys N2, Rockwell, DH+, Profibus, DeviceNet, SNMP and many more. Over 110 in fact.
What is a Modbus TCP to MQTT IoT Gateway and how does it work?
Function: Acts as a bridge between Modbus TCP-based devices and IoT platforms using MQTT protocol. Purpose: Converts industrial Modbus TCP data into MQTT messages for real-time communication. Usage: Integrates sensors, controllers, and other Modbus devices with cloud platforms. Key Benefits: Enables remote monitoring and control Supports predictive maintenance with real-time alerts Improves data management and automation Applications: Widely used in industries like manufacturing, energy management, and building automation for efficient operations and remote access to industrial equipment.
What two modes of data transfer does File Transfer Protocol support?
FTP (File Transfer Protocal) supports both ASCII & Binary.
Schneider electric open architecture?
Modbus.
What is oem extended ascii?
Extended ASCII is 8-bit encoding which is wider than standard ASCII and also includes all characters from standard ASCII encoding.ASCII is 7-bit, 128 possible values; Extended ASCII is 8-bit , 256 possible value;128 first characters of Extended ASCII is the same as ASCII, next 128 are additional. This why it is called Extended ASCII.What is ASCII?ASCII is mainly English language characters encoding, that is used for representation of text information.
What is the function of a Modbus splitter?
Its function is to relay data signals sent via master to its slave. It also serve as a junction where you can interconnect several Modbus devices.
In the ASCII code the letter A and the letter a have the same value?
False they don't have the same value
How do you interface modbus to controller and to PC?
You can do it directly from a serial port of the PC to the CPU's Modbus port (if you are using a Modicon controller). The standard used would be RS-232.
