Hi.  
We recently got our ignition connected to the S7-1200 PLC, but any and all tags added to ignition get  
“[CONFIG\_ERROR] null”

PUT/GET is enabled in the plc.  
I have added tags like DB44,X122.0 which is a boolean in DB44, just to test, it gets last value “n/a”, and quality is empty.

How to gain access to the tags, any ideas?

EDIT: Now when i checked wrapper.log i find this:

`INFO | jvm 3 | 2016/07/28 07:21:34 | WARN [CreateMonitoredItemsService] [07:21:34,881]: Returning ServiceFault for request: [CreateMonitoredItemsRequest requestHandle=25814]. StatusCode=StatusCode[Severity=Bad, Subcode=Bad_InternalError]

[attachment=0]stale.png[/attachment]Hi.

I checked aroun, and changed the OPC UA Listen IP to the servers IP, to now it went from [CONFIG\_ERROR] to [STALE] instead  
Anyone with any idea how to get the tags to read from a Siemens S7-1500?

> [@anna](#):

> Stefan, DB44,X122.0 is invalid syntax. X is used to address bits, so you should not be specifying the bit after the dot again. Instead, try `DB44,X122`

@anna Sorry anna, but you are wrong. In Siemens PLC you MUST specify bit after the address.  
[device\_name]DB44,X122.0 is correct syntax.

zxcslo, stand corrected 😊 - must have been thinking about something else (like integer offsets)
