Hello, can somebody help me. I try to read data from sensors which are connected to I/O module using PLC WAGO Edge Controller. They are connected through Modbus RTU RS485.

utQuery : typMbQuery := ( bUnitId := 1, // Slaveaddress
bFunctionCode := 16#04, // read input registers
IIdentifyObject := myBaseIdentification, // only needed for FC43
uiReadAddress := 2000, // Startaddress
uiReadQuantity := 10, // Quantity of wanted registers
uiWriteAddress := 0, // not needed for FC4
uiWriteQuantity := 0, // not needed for FC4
awWriteData := [124(0)] // not needed for FC4
);

Unfortunately, i couldnt get the data but when i tried using modbus poll, the data can be displayed. Thank you for your help.
