Hello everyone,
Atlast i found the solution. Every parameter can be read by SDO command. In CIA405 library the SDO_Read4 can be used for reading the parameter from the drive at runtime.
Syntax
fbname : CIA405.SDO_READ4;
fbname( NETWORK:= (networkid +1), Enable :=sdoEnable, CONFIRM => sdoConfirm, DEVICE := NodeID, CHANNEL :=1, INDEX := 16#3008, SUBINDEX := 16#F, DATA =>(Pointer toArray of 4 bytes), DATALENGTH => dataLengthSize, ERRORINFO => o_sdoError);
Change sdoEnable to true . Make it false when sdoConfirm become true.
