Hello,

I am very new to connecting a Siemens PLC to Ignition- I have connected it and am reading 1 boolean tag. I am trying to connect to a word tag that appears to be in a DB? I am not sure what the exact structure should be. The tag is DB50.DBW154.  
Any advice?

[https://docs.inductiveautomation.com/display/DOC81/Siemens#Siemens-ConfiguringSiemensAddressing](https://docs.inductiveautomation.com/display/DOC81/Siemens#Siemens-ConfiguringSiemensAddressing)  
The syntax is: `[s7_300]DB50,W154` or `[s7_300]DB50,I154`

I figured out the problem, the tag was simply DB50,i154. This was due to my lack of knowledge in Siemens S7 Navigation.
