Key Features of Modbus Poll 12.1.1.2487
Real-Time Communication Monitoring
Modbus Poll provides real-time monitoring of Modbus registers, allowing users to visualize data changes instantly. It supports both Modbus RTU (serial) and Modbus TCP/IP (Ethernet) communication, making it suitable for diverse environments.
Multi-Tab Interface
The software allows users to open several tabs, each representing a different Modbus slave. This makes it easy to compare responses or test multiple devices simultaneously without confusion.
Easy Register Editing
You can manually change register values in the table to simulate different conditions. This helps engineers test system behavior without connecting physical hardware.
Built-In Scripting Support
Using built-in Visual Basic for Applications (VBA) scripting, users can automate repetitive tests, create custom data processing scripts, or generate reports automatically.
Error Checking and Diagnostics
Modbus Poll includes advanced error-checking tools that help detect incorrect addresses, timeouts, or invalid CRCs, ensuring the reliability of your Modbus setup.
What’s New in Modbus Poll 12.1.1.2487
The latest release brings several improvements to boost performance and compatibility with modern automation systems:
-
Enhanced Modbus TCP stability with faster response times.
-
Updated UI for better readability and easier navigation.
-
Improved VBA scripting engine for faster execution.
-
Additional logging options for communication diagnostics.
-
Optimized performance when handling large data tables.
