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 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.
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.
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.
ASCII protocol same of Modbus protocol?
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.
How does SCADA communicate with PLC?

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.
