Overview

This package contains a ROS node and a RViz panel to allow users to fetch data over Modbus TCP and publish them on ROS topics.

It can be used through the service (command line or programming) and also thanks to a RViz panel.

  • Multiple handlers can be created to establish as many connections as needed to Modbus TCP servers
  • Multiple data can be fetched at the same time
  • For each data the rate, endiannes and topic can be specified

Supported types are: - bool - int8 - uint8 - int16 - uint16 - int32 - uint32 - int64 - uint64 - float32 - float64

Depending on the data width multiple registers are fetched. Eg: int32 requires to fetch two modbus registers (16 bits each)

:information_source: The panel configuration is saved/loaded in the RViz configuration file, this includes the base topic and handlers configuration. You don't need to configure the handlers again.

:warning: When trying to connect to an IP address that is not reachable / does not host a Modbus TCP server the service will hang for a very long time (~ 2 minutes)
