The Averaging object is described by the BACnet standard as a recording medium of visible value characteristicsover a specific time interval.These specific sampled values may take the fol…

When a BYTE is sent from a serial device (BACnet MSTP thermostat) to a USB to 232/485 converters (USB-COMI-SI-M) it is cached on the USB converter until one of two things happened.…

I was ask this question to day What would happen if you had two BACnet MSTP devices with different MAC address but the same BACnet Device ID (Node ID) on the same network and…

CAS BACnet Watchdog monitors and records BACnet packets and message from certain Devices and Objects.Messages can then be flagged depending on certain criteria.For example:Let's say you h…

1-Wire communication protocol, known for its simplicity and robustness, enables data transmission over a single wire. However, the length of a 1-Wire bus, crucial for network reliability, is determine…

All devices on a BACNet network are effectively peers. This means that any device (we take device here to mean any Bacnet capable entity – device or software application) can…

The BACnet spec defined the media for MSTP as follows (2004):"An MS/TP EIA-485 network shall use shielded, twisted-pair cable with characteristic impedance between 100 and 130 ohms. Distributed capaci…

What happens if you need to learn about a Lonworks network and its devices, but you haven't been provided with the database, or you don't have LonMaker? NodeUtil is a Lonworks utility that can be use…

The Event Enrollment object is defined by the standard as information related to the management of events for BACnet systems. Events are essentially changes in the value of any property concerning any…

The article discusses some of the typical difficulties encountered when handling 32-bit data types via Modbus RTU and offers practical help for solving these problems. The point-to-point Modbus pro…

After configuring the Devices (and Objects), Ports, and Names in the Visual Test Shell (VTS) the next step is to begin sending packets. Packets can be sent…

After configuring some devices and objects, the next step is to configure the ports (or connections) to connect to these devices.  For the Visual Test Shell (VTS) to be able to communicate with a devi…
