@MaKa

Working on an application currently that is done in Siemens TIA V15 with a CCGX in Demo Mode and successfully reads the .system tags over Modbus TCP/IP to a S7-1200 PLC.

Moving onto writing data to the CCGX from the PLC next but can share insights if still wanted?

Ahoj všichni,

Mám problém s komunikací modbus tcp s jednotkou cerbo gx.


Vybral jsem ID100 v dostupných službách CERBO GX.


Podle dokumentace jsem zvolil nejjednodušší dotaz na proud přes převodník toku, tedy ID:100, MB_MODE = 0 /čtení dat/, MB_DATA_ADDR: 808, DATA_LEN: 1.

Bohužel se mi zobrazuje chyba 16 # 8384 - Chyba v hodnotě dat pro funkci 5 ???


Pokud používám Simply Modbus TCP Client 8.1.2, tak mi CERBO GX odpovídá bez problému.


Proč Cerbo vrací ID255 cybu, když žádá o jednotku ID100?


Nenapadá vás kde by mohla být chyba??


Viz obrázky.


Moc děkuji za případné odpovědi. Petr
