Since they were both parts of the original Modbus protocol specification, you might be wondering what's the difference between Modbus ASCII and Modbus RTU. Modbus RTU employs binary coding and CRC error-checking. These choices were made for the sake of efficiency and are the main reason that the RTU mode is the one most commonly used in industrial settings.

Adressierun Read and write operations are sent through Modbus messages using coils. A coil consists of 16-bit words and binary registers. A slave can only respond to a received message and never initiates communication with the master. Each slave device attached to the RS485 bus in parallel is assigned a unique Modbus slave ID. All Modbus communication begins with the slave ID being sent, either to alert. If you or your company are looking for a way to monitor your Modbus devices, try out everything you read in this Telegraf plugin.
