<div class="markdown_content"><p>Hi,</p> <p>Hi,</p> <p>In our workshop we have a PFC200 and a module 750-653/003-000 laying around my table. Our workshop project is still in the e!cockpit environment and we started trying to migrate it to CODESYS 3.5.</p> <p>We have a few energymeters that are read via MODBUS RTU to our current PFC200 but using 750-652 module. My last try with the 750-653 module was not successful with the e!cockpit therefore I decided to try it with COESYS.</p> <p>Now I use FbMbMasterSerial function block but there is no response from the energymeters and no errors are generated for the 750-653 module.</p> <p>The attached pictures show the settings for the 750-653 module and the FbMbMasterSerial function block.</p> <p>Best Regards<br/> Konstantin Kolev</p></div>
