The Telegraf Modbus input plugin allows users to collect data from Modbus devices via Modbus TCP or RTU/ASCII connections. The plugin supports digital variables such as discrete inputs, coils, holding registers, and input registers, and can be configured using a sample configuration file. InfluxDB 2.0 recently launched templates that include prepackaged configurations for common setups, including the Modbus template contributed by Ray Farias. This template includes an Island Pulse Demo Modbus Device repository for a working demo device. The plugin and template are designed to make it easy to monitor Modbus devices with InfluxDB.
