What is Modbus?

Modbus remains the most widely available protocol for connecting industrial devices. The Modbus protocol specification is openly published and the use of this protocol is royalty-free.

The device requesting the information is called the Modbus Master and the devices supplying information are Modbus Slaves. In a standard Modbus network, there is one Master and up to 247 Slaves, each with a unique Slave Address from 1 to 247. The Master can also write information to the Slaves.
