Data acquisition is the process of sampling real world physical information and the conversion of the samples into digital numeric values that computers and controllers can understand. Modbus based Data Acquisition devices include RTD, Thermistor, Thermocouple, Voltage, Current, Strain Gauge, Counter, Frequency, Relay, Digital Input, and Digital Ouptut and are widely used in industrial automation, remote monitoring, wastewater monitoring, process control, and building automation. This training talks about Modbus RTU and Modbus TCP Protocols, Modbus Data Acquisition Technology, Modbus Data Logging, Stand Alone Modbus Systems, and how to configure PC Based Modbus Systems with SCADA Software.

History of Modbus
• Modbus is a Serial Based Communications
Protocol
• Widely used industrial communications for
instrumentation, control and data acquisition
devices
• Originally published by Modicon (now Schneider
Electric) in 1979 for use with its Programmable
Logic Controllers

Data Acquisition
Data acquisition (abbreviated DAQ) is the process of sampling of real
world physical conditions and conversion of the resulting samples into
digital numeric values that can be manipulated by a computer.

7. Making Data Acquisition Easy
Modbus RTU Protocol
• Modbus RTU: an open, serial (RS-232 or RS-485)
protocol derived from the Master/Slave
architecture.
• It is a widely accepted protocol due to its ease of
use and reliability.
• Modbus RTU is widely used in Industrial
Automation Systems.

8. Making Data Acquisition Easy
Modbus TCP Protocol
• Modbus TCP: simple, vendor-neutral communication
protocols intended for supervision and control of
automation equipment.
• Specifically, it covers the use of Modbus messaging in
an 'Intranet' or 'Internet' environment using the
TCP/IP protocols.
• The most common use is for Ethernet networking of
PLC's, I/O Modules, and ‘Gateways' to other simple
field buses or I/O Networks.
