Summary

Implements a Modbus Master (Client) over TCP/IP to communicate with Modbus TCP slave devices.

Description

The **Modbus Client (Master) TCP/IP Protocol** component allows sending and receiving Modbus requests over a TCP/IP network. You can configure the maximum number of simultaneous **Transactions** and the **Response Timeout** in milliseconds. This component is useful for industrial automation, building management, and networked sensor systems where Modbus TCP communication is required.
