Modbus TCP. Connection between PM581 and PM554
We are trying comunicate a PM581-ETH with a PM554-ETH by modbusTCP. We only can configurate the PM554, because PM581 is installed and we don't have direct acces to PLC.
Basicly we suppose that the PM581 is configure as server (slave), because there are a touchpanel connected by Modbus RTU. And (COM 2) is configured like slave. With the PM554 as client (master) the ETH_MOD_MAST function module show error number 12289 and if it is server, the ETH_MOD_MAST show error number 12325.
We have attached a pdf with some screenshots, with parameters of PM581 and PM554.
Thank you very much,
