# Modbus Task Blocks

The Modbus plugin provides two protocol-specific Task Blocks that you can use to implement Modbus client read and write operations. These blocks are available under the Communication > Modbus node of the Task Editor Toolbox.

- Read Data: Reads the data of the remote Modbus Server device to which the selected Modbus Client device is connected.
- Write Data: Writes the data of the remote Modbus Server device to which the selected Modbus Client device is connected.

See the applicable topics for more information on configuring and using these Task blocks.

Note: Similarly to the Modbus Devices, the Modbus task blocks are only available if the Modbus plugin has been installed and loaded into the Cognex Designer project.
