Once registered, follow these steps to begin polling data from a slave device:
Establish Connection (F3): Define your protocol (Modbus RTU, TCP/IP, etc.) and physical port settings.
Define Read/Write (F8): Set the Slave ID, Function Code (e.g., 03 Read Holding Registers), and the starting Address.
Addressing Note: Modbus Poll uses base 0 (protocol) addressing by default. If your device manual starts at 40001, enter "0" in Modbus Poll.
Monitor Data: Data will appear in the grid. Double-click any cell to write a new value to the register. Common Troubleshooting
Timeout Errors: Ensure the correct COM port or IP address is selected. Use ping to verify network connectivity for TCP devices.
Invalid Data Address: If you receive an "illegal data address" error, you may be requesting a register that does not exist on the slave device. Try decrementing your address by 1 if switching from base 1 to base 0.

It is frustrating to buy a new key only to see "Invalid hardware code." Here is the fix matrix:
| Error Message | Cause | Solution |
| :--- | :--- | :--- |
| Invalid License File | The .lic file does not match your hardware ID. | You must send a new Request Code from this PC to the vendor. |
| License Expired | You are using a trial key or a time-limited student key. | Purchase a Standard or Professional new key. |
| Access Denied (Registry) | Windows UAC blocked the key write. | Run Modbus Poll as Administrator once to install the key. |
| Key for older version | You are using v6 key on v7 software. | Download the legacy version (v6.5) or upgrade your key. |
If you have lost your key or are installing on a new machine, follow these steps:
| Feature | v8 (Legacy) | v10 (New) | | :--- | :--- | :--- | | Poll Rate (100 coils) | 5ms | 4ms (Optimized thread pool) | | UI Lag (4K monitor) | Severe | None | | CSV Export Speed | 500 rows/sec | 15,000 rows/sec | | Simultaneous Connections | 8 (stable) | 32 (tested limit) |
The term "poll key" isn't standard in Modbus documentation but could refer to a few different concepts depending on the context:
Modbus Address or Slave ID: Sometimes, a "poll key" might colloquially refer to the unique identifier (address) of a Modbus device on the network. Each device on a Modbus network has a unique address (or slave ID), which the master uses to identify and poll the device.
Specific Data Points or Registers: In some contexts, a "poll key" could refer to a specific data point or set of registers in a device that are being polled. For example, a particular register in a device might be designated as a "poll key" to indicate its importance or to simplify the process of requesting data from it.
Software or Licensing Key: In software applications that communicate using Modbus, a "poll key" might refer to a licensing or activation key required to enable Modbus polling capabilities within the software.
