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

Olá a todos os especialistas, preciso de ajuda.
Estou iniciando um projeto no modbus e ao inserir instrução conforme mostrado, ele não se comunica mais online.
Eu esqueci de introduzir o contato da escada antes.

Uma mensagem de porta de inicialização foi mostrada, o que isso significa?

Eu preciso programar no modbus, quais passos são necessários?
Isso acontecerá novamente, pois preciso programar e testar com um inversor yaskawa ao mesmo tempo com a mesma porta?
obrigado

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.
