| | === Err led alerts === |
| | |
| | | **N°**\\ **flashing** | **Error** | **Description** | **Recommended operations** | |
| | | **1** | **Bus error** | Bus not configured as described in the application. | To verify the correspondence between the configuration of the QMOVE application (BUS section of the configuration unit) and that of the productr (cards available in the BUS). | |
| | | **2** | **CheckSum Error** | The integrity check on the retentive variables has failed. (To see the Reset Error Checksum chapter) | It is necessary to restore data from a backup machine (file with DAT extension) or clear the error with the function of the system and reintroduce the values manually. | |
| | | **3** | **Index Out of Bound** | Array index is pointed to a nonexistent element | With Qview environment you can open the editor of a unit and with the "Edit->Go to PC" command you see the line that caused the error. Typically the value used as the index has a value less than 1 or greater than of the array size. | |
| | | **4** | **Program Over Range** | The selection index program within the DATAGROUP has attempted to access a non-existent program. | With Qview environment you can open the editor of a unit and with the "Edit->Go to PC" commnand you see the line that caused the error. Typically the value used as the index has a value less than 1 or greater than of the array size. | |
| | | **5** | **Step Over Range** | The selection index step within the DATAGROUP has attempted to access a non-existent step. | With Qview environment you can open the editor of a unit and with the "Edit->Go to PC" commnand you see the line that caused the error. Typically the value used as the index has a value less than 1 or greater than of the array size. | |
| | | **6** | **Division By Zero** | The denominator of a division operation of the user program has value zero. | With Qview environment you can open the editor of a unit and with the "Edit->Go to PC" commnand you see the line that caused the error. | |
| | | **7** | **Syntax Error** | The application program has an invalid instruction | his error may appear because the program counter met the QCL END statement. | |
| | | **8** | **Watch Dog Error** | A CAN module is not working properly, or an expansion card has a hardware problem. | With Qview environment you can open the "Monitor->Bus" panel and in the "Watchdog Bus" column shows the card that caused the problem. | |
| | | **9** | **Stack Error** | The application program has used all levels of subroutine call permissions | With Qview environment you can open the editor of a unit and with the "Edit->Go to PC" commnand you see the line that caused the error. Analyze the flow of execution of the unit. The nestings of subroutines have a limit, beyond which it generates this error. | |
| | |
| | === Hardware error codes === |
| | |
| | If a malfunction is detected when starting of any peripheral devices, the system hangs and the error is reported by the blinking of the only {{led:led_lamp.jpg?direct&20}} led err while all the other leds remain OFF. |
| | In the table you can see the number of flashes that indicates the error: |
| | |
| | ^Number of flashes^Error^ |
| | | 1 |Display| |
| | | 2 |FPGA| |
| | | 3 |Media| |
| | | 4 |Bootloader| |
| | | 5 |FW| |
| | | 6 |Bus| |
| | | 7 |//Inactive signal//| |
| | | 8 |//Inactive signal//| |
| | | 9 |Exception| |
| | . |
| | ^:important:^Each of these reports indicates a serious error. The product must be sent to the customer support QEM.^ |
