roghenr Posted May 30, 2022 Report 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

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.
