Seu simulador tem a opção de ser mestre ou escravo?

Que tipo de MODBUS você está usando?

I'm using modbus serial rtu.
I have modbus that simulates slave, but it doesn't work.
I wanted to use Vision 130 as a master in tests with VDF

Você precisa adicionar este programa ao PLC (no caso de Modbus TCP):

@Gabriel Franco, eu sempre apenas penduro meu MODBUS IP SCAN_EX FB diretamente no trilho esquerdo. Por que você inclui SB 2? Você está esperando que a primeira varredura do PLC cause um problema?

Gabriel, this is only minor, but I'm intrigued why you activate SB168 in the ladder itself, rather than simply setting it on powerup?

cheers, Aus

Its the way to remember to myself and to my coleagues that its madatory to set it in all programs using Ethernet.

I set all requiered power up values in ladder rather than Visilogic option.
