BACnet Server TrendLog Example C#

A simple BACnet Server example in C# to demonstrate functionality to Import and Export data from Trend Log Objects using the CAS BACnet Stack.

Releases

Build versions of this example can be downloaded from the Releases page.

Installation

Download the latest release zip file on the Releases page. Copy CASBACnetStack_x64_Release.dll from the CAS BACnet Stack into the release folder. Please contact Chipkin Automation Systems for access to the CAS BACnet Stack. Launch client by using the following command:

dotnet BACnetServerTrendLogExampleCSharp.dll

Requires .NET Core 3.0+

Usage

Trendlog object is tied to Analog Input 1 and is updated every 30 seconds. Trendlog Multiple is tied to Analog Input 1, Analog Input 2, Binary Input 3, and Multi-State Input 4.

Pre-configured with the following example BACnet device and objects:

Device: 389000 (Example Trending Device)
- analog_input: 1 (AI - Auto Increment)
- analog_input: 2 (AI - Manual Increment)
- binary_input: 3 (BI - Binary Input)
- multi-state_input: 4 (MSI - Multi-State Input)
- trend_log: 10 (TL - Trend Log (AI1))
- trend_log_multiple: 20 (TLM - Trend Log Multiple (AI1, AI2, BI3, MSI4))

The following keyboard commands can be issued in the server window:

H: Display help menu
F1: Display Version Info
Up Arrow: Increment Analog Input 2 Present Value
Down Arrow: Decrement Analog Input 2 Present Value
B: Backup TrendLog to File
S: Backup TrendLogMultiple to file
Q: Quit the program

Build

A Visual Studio 2019 project is included with this project. This project also auto built using Gitlab CI on every commit.

Copy CASBACnetStack_x64_Debug.dll, CASBACnetStack_x64_Debug.lib, CASBACnetStack_x64_Release.dll, and CASBACnetStack_x64_Release.lib from the CAS BACnet Stack project into the /bin/netcoreapp3.1/ folder.
Use Visual Studio 2019 to build the project. The solution can be found in the /build/BACnetServerTrendLogExampleCSharp/ folder.
