BAS Communication Failure Resolution – BACnet MS/TP Network

A facility experienced intermittent communication failures across multiple BAS devices, impacting system monitoring and control.

Problem

Operators observed:
– Devices going offline randomly
– Missing or delayed data points
– Alarm failures

Approach

Operators observed:
– Devices going offline randomly
– Missing or delayed data points
– Alarm failures

Findings

– Multiple devices configured with mismatched baud rates
– Duplicate MAC addresses causing network conflicts
– Missing and improper termination resistors leading to signal reflection

Solution

– Standardized baud rate across all devices
– Reassigned unique MAC addresses
– Installed proper end-of-line termination
– Optimized Max Master settings for network efficiency

Results

– Eliminated communication timeouts
– Restored full system visibility
– Improved data reliability and alarm functionality
– Enhanced long-term network stability
