I am having difficulties connecting these Siemens PLC tags into Ignition:

_**db11.dbx1352.3 (Boolean data type)**_  
Converted to Ignition as [PLC Line5]DB11,X1352.3 Also I used [PLC Line5]DB11,DI1352.3

_**db105.dbx0.0 (Boolean data type)**_  
Converted to Ignition as [PLC Line5]DB105,X0.0 Also I used [PLC Line5]DB105,DI0.0

_**db104.dbx0.0 (Boolean data type)**_  
Converted to Ignition as [PLC Line5]DB104,X0.0 Also I used [PLC Line5]DB104,DI0.0

_**db105.mmt125.hmioutmetercounter (Integer data type)**_  
Converted to Ignition as [PLC Line5]DB105,mmt125.hmioutmetercounter  
Also I used [PLC Line5]DB105,T125.hmioutmetercounter  
_**db2066.20 (Float data type)**_  
Converted to Ignition as [PLC Line5]DB2066,20

_**db303.dbd0 (Integer data type)**_  
Converted to Ignition as [PLC Line5]DB303,REAL0

Any idea what I am doing wrong?

Here are the errors I am getting when I tried the above:

I tried to follow [Siemens - Ignition User Manual 8.1 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC81/Siemens), but I must be missing something. Please HELP!

Hi @Alfonso_Campos,

Didi you try everything above? Put/Get mechanism, optimized block access on off ?

Can you share more detail about the plc configuration and program ?
