Exception Troubleshooting
| No. | Exception Information | Corresponding Parameter | Solution |
|---|---|---|---|
| 1 | Parameter "xxx" cannot be empty | Parameter name | Input the xxx parameter. |
| 2 | Device "xxx" does not exist | Device name | Modify device parameters or add corresponding device. |
| 3 | Failed to write xxx "xxx" type data to address "xxx" | Address,Count,Type | Ensure PLC supports specified data type, and specified address is correct and accessible. |
| 4 | Failed to write xxx "xxx" type data to address "xxx", negative values exist in data | Address,Count,Type | Ensure no negative values in input data, or change data type to signed. |
| 5 | Input length xxx is greater than data length xxx, using data length instead. | Length value,Data length | Reduce data length or increase data count. |
