Introduction to Modbus Modbus is typically used for Supervisory Control and Data Acquisition (SCADA)-style network communication between devices. For example, a large server may be used to master a programmable logic controller (PLC) or programmable automation controller (PAC), while that PLC/PAC ma...

Modbus – introduction OT protocols are communication protocols designed for the exchange of control messages on industrial networks. The MODBUS protocol, developed by Modicon for use with its programmable logic controllers (PLCs), provides client/server communication between devices connected on different...
The MODBUS/TCP protocol was released as a (de facto) automation standard. Modbus communication protocol is a general communication protocol that has been widely used in today's industrial control field.
