<div class="markdown_content"><p>I have set up Modbus TCP Client in Codesys 3.5.12 to read/write to are remote IO and I want to be able to change the IP of a Modbus TCP server (slave) in Codesys if the IP of the remote IO changes.<br/> The change of the slave IP should be made through a HMI or WebVisu. </p> <p>Modbus TCP slave has a method called UpdateCommunicationSettings with IP and Port as parameters.<br/> It says that "Fails (return value !=0) if TCP connection is currently established. (--&gt;Use Enable Property to connect/abort)".</p> <p>Where do I find this Enable property?</p></div>
