Issue
When using a BAS terminal connected to a PIU (Protocol Interface Unit), users may encounter unexplained system messages such as:
“Message No. 19920 not available. Please contact Product Support.”
These messages indicate that the terminal received a system message from the PIU that is not defined in the local Messages.ini file.
Product Line
Satchwell BAS & Sigma
Environment
BAS PIU and Sigma Pre-release 4 System Messages
Cause
The Messages.ini file used by the BAS terminal has a maximum size limit of 64KB. Due to this constraint, not all possible PIU error messages are included by default. As a result, some messages—especially those from less commonly used subsystems—may be missing.
