roghenr Posted May 30, 2022 Report Share Posted May 30, 2022 Hi all experts I need help. I'm starting a project in modbus and when inserting instruction as shown, it no longer communicates online. I forgot to introduce ladder contact before. An initialize port message was shown, what does this mean? I need to program in modbus, what steps are necessary? Will this happen again since I need to program and test with a yaskawa inverter at the same time with the same port? thanks Quote Link to comment Share on other sites More sharing options...

Isso acontecerá novamente, pois preciso programar e testar com um inversor yaskawa ao mesmo tempo com a mesma porta? obrigado Quote Link to comment Share on other sites More sharing options...
MVP 2022 Flex727 Posted May 30, 2022 MVP 2022 Report Share Posted May 30, 2022 You normally place SB 2 in front of configuration function blocks. Quote Link to comment Share on other sites More sharing options...

Please read this topic, I recommended to put an additional card for the ability to configure modbus and watching the PLC online through the Visilogic. You can also use additional Ethernet card for Visilogic connection. Quote Link to comment Share on other sites More sharing options...
