I am trying to read the below tags from PLC: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/c/c8c78c547a7c2875fcc4e935597d4708da7a444b.png) However, I get the message below: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/a/abd31a7e9ef02b5027cefc777ea6f6eedd19486b.png) Below is the OPC Item Path: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/1/19279d019ec97d0567381a23ba70d13abd4b8e4e.png) If I have a %MW30 Tag with Int datatype, is the syntax for that tag in Ignition [DeviceName]MI30? Sorry if this has been asked already. ---

Sorry to ask the obvious but Did you try [DeviceName]MW30 ? And you have other tags working so it’s not a connection issue ? ---

To read the value as a signed Integer MI30 is correct, but MW30 should also be working. Did you adjust the security settings as described in [this knowledgebase article](https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/29/0/connecting-to-siemens-s7-1200-and-s7-1500)? ---

I have tried [DeviceName]MW30 and the issue is still there. Interesting thing is my boolean tags are working fine. ---

I adjusted the security settings and the issue is still there. Do you know what else could cause it? Is my syntax wrong? ---

I figured out what the solution was, there was a trailing space on the OPC Server name I just deleted space in the OPC Server name: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/2/23e395c73a983939a0041ab4bbfa63566d3ef08e.png) Good Reads: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/d/d69e6ace1bd30fc47d42a492abbe6d6b3080afb5.png)
