First object in a Sigma IC3-SNP always displays it's default value

[Product_Support]

Issue

In Sigma System Manager, the object associated with the first entry in the Gateway.txt file of an S-IC3-SNP integration controller consistently displays its default value, rather than the expected mapped value.

Product Line

Satchwell BAS & Sigma

Environment

Sigma IC3-SNP

Cause

This issue arises due to the way the S-IC3-SNP controller processes the object mapping file (Gateway.txt). Specifically, the first line in the file is not correctly interpreted, causing the first object to revert to its default value.

Note: This behavior does not affect earlier versions such as S-IC-SNP.

Resolution

Steps to Resolve:

1. Edit the Gateway.txt file.
2. Insert a dummy line at the beginning of the file.
   This placeholder prevents misinterpretation of the first actual object.

   Example

   Original Gateway.txt:

   51,13,R,114,2,0,0,3,1 ;Room temperature  
   52,13,R,114,28,0,0,3,1 ;PIR Status  
   53,13,R,160,6,0,0,3,1 ;Heating Valve Open
   

   Revised Gateway.txt with Dummy Line:

   51,13,R,114,2,0,0,3,1 ;Dummy text entry  
   51,13,R,114,2,0,0,3,1 ;Room temperature  
   52,13,R,114,28,0,0,3,1 ;PIR Status  
   53,13,R,160,6,0,0,3,1 ;Heating Valve Open
   

3. Save and reload the configuration in Sigma System Manager.

✅ The first object should now display its correct mapped value.
