- Modbus RTU/ASCII Master
Developers can purchase only the drivers they need.
Licensing
ASComm.NET is commercial software with several license models, including Machine Edition, Developer Edition, site licenses, and enterprise licenses. Automated Solutions also offers a fully functional 30-day evaluation version. The EULA prohibits unauthorized copying, reverse engineering, or redistribution outside the license terms.
ASComm.NET Installation and Setup
Setting up ASComm.NET involves installing the library, configuring your development environment, and establishing communication with your PLC or industrial device.
1. Download ASComm.NET
Download the latest version from the official Automated Solutions website. The installer includes the required libraries, documentation, sample applications, and licensing tools.
2. Install the Software
Run the installer with administrator privileges and follow the installation wizard. During installation, you can choose which communication drivers (such as Allen-Bradley, Siemens, or Modbus) to install.
3. Activate the License
After installation:
- Launch the License Manager (if required by your edition).
- Enter your purchased license key or use the evaluation license.
- Verify that the correct drivers are activated.
4. Create a New Project
Open Microsoft Visual Studio and create a new project using your preferred .NET Framework version (supported versions depend on the ASComm.NET release).
Typical project types include:
- Windows Forms
- WPF
- Console Application
- Windows Service
- ASP.NET Application
5. Add ASComm.NET References
Reference the required ASComm.NET DLLs in your project.
Typical steps:
- Right-click References
- Select Add Reference
- Browse to the ASComm.NET installation folder
- Add the required communication libraries
6. Configure PLC Communication
Before reading or writing PLC data, configure:
- PLC IP address
- Communication port
- Rack and slot (for supported PLCs)
- Communication timeout
- Polling interval
- Driver-specific parameters
7. Test the Connection
Use the included sample applications or write a simple test program to:
- Connect to the PLC
- Read a tag or register
- Write a test value (if appropriate)
- Disconnect cleanly
Successful communication confirms that your network settings and driver configuration are correct.
Performance Optimization
Industrial applications often require fast, reliable communication with minimal latency. The following practices can improve ASComm.NET performance.
Use Block Reads
Reading multiple values in a single request is generally more efficient than reading each tag individually.
Instead of:
- Read Tag1
- Read Tag2
- Read Tag3
Group compatible addresses into a single read operation whenever your PLC and protocol support it.
Reduce Polling Frequency
Polling too quickly increases network traffic and CPU usage.
Typical polling intervals:
- Critical control: 50–100 ms
- HMI displays: 250–500 ms
- Historical logging: 1–5 seconds
Choose the slowest interval that still meets your application’s requirements.
Use Asynchronous Communication
Asynchronous operations allow the user interface to remain responsive while communication occurs in the background.
Benefits include:
- Better UI responsiveness
- Improved scalability
- Higher throughput when monitoring multiple devices
Organize Tags Logically
Group related PLC variables together.
For example:
- Production counters
- Temperature sensors
- Motor status
- Alarm bits
Logical organization can simplify code and may reduce communication overhead.
Minimize Connection Overhead
Avoid repeatedly connecting and disconnecting from the PLC.
Instead:
- Open one connection
- Reuse it throughout the application
- Close it only when the application exits or communication is no longer needed
Optimize Network Configuration
For Ethernet communication:
- Use industrial-grade switches where appropriate.
- Prefer wired connections over Wi-Fi for PLC communication.
- Ensure PLC and PC are on the correct subnet (or that routing is properly configured).
- Avoid excessive broadcast traffic on the control network.
Avoid Unnecessary Writes
Only write values when they have actually changed. This reduces network traffic and unnecessary PLC processing.
Monitor Communication Statistics
Track metrics such as:
- Communication errors
- Retry counts
- Average response time
- Packet loss
- Connection uptime
Monitoring these values helps identify performance bottlenecks before they affect production.
Troubleshooting
When communication problems occur, a systematic approach can help identify the cause.
Cannot Connect to the PLC
Possible causes:
- Incorrect IP address
- Wrong communication driver
- Incorrect rack/slot configuration (where applicable)
- Firewall blocking communication
- PLC powered off
- Network cable disconnected
Check network connectivity using tools like ping (if supported by your network) and verify all communication parameters.
Read or Write Operations Fail
Possible reasons include:
- Invalid tag or register address
- Insufficient PLC permissions
- Incorrect data type
- Communication timeout
- PLC in a restricted operating mode
Verify the address and data type against the PLC program.
Slow Communication
Potential causes:
- Polling too frequently
- Reading too many individual tags
- Network congestion
- High PLC CPU utilization
- Excessive simultaneous client connections
Grouping reads, increasing polling intervals, and reducing unnecessary requests can often improve performance.
Random Disconnects
Intermittent communication may result from:
- Faulty Ethernet cables
- Unstable network hardware
- Duplicate IP addresses
- PLC reboots
- Power interruptions
- Firewall or antivirus interference
Review network logs and ensure all devices have stable power and unique IP addresses.
Licensing Issues
If the software reports licensing errors:
- Confirm the license is activated.
- Verify that the installed driver matches your license.
- Ensure the evaluation period has not expired.
- Check whether your license is tied to specific hardware.
If problems persist, contact Automated Solutions support with your license details.
Best Practices for Reliable Operation
- Keep regular backups of your project and PLC program.
- Test changes in a development environment before deploying to production.
- Log communication errors for later analysis.
- Use appropriate timeout and retry values for your network.
- Keep Windows, Visual Studio, and ASComm.NET updated with supported releases.
- Follow the documentation for the specific PLC protocol and driver you are using.
These practices help improve reliability, simplify maintenance, and reduce downtime in industrial automation applications.
