Supported platforms: CODESYS 2.3, CODESYS 3.5, CODESYS 3.5 SAFETY

 

General command (for 3000 series, 4000 series and 5050 units)

To remove PLCopen application:

 

1. Send a stop command to CODESYS runtime:

 

COB-ID	DLC	D0	D1	D2	D3	D4	D5	D6	D7
600h + node-ID	8	2Fh	25h	10h	1h	4h	0h	0h	0h

 

2. Wait until you get a response. If the control unit is booting continuously, it can take several attempts to get a response. If it is not possible to get this command through, there are some optional commands which can be used with some control unit platforms. See the following sections.

 

3. Send a reset original command to control unit command to CODESYS runtime.

 

This command also clears the retain and persistent retain variables

 

 

COB-ID	DLC	D0	D1	D2	D3	D4	D5	D6	D7
600h + node-ID	8	2Fh	25h	10h	1h	13h	2h	0h	0h

 

4. Power boot the control unit.

 

 

 

Optional command for 5050 (to clear the application and not to reset persistent and retain persistent variables)

This command does not clear the retain and persistent retain variables

 

 

To clear the application and to keep persistent and retain persistent variables:

 

1. Send a stop command to CODESYS:

 

COB-ID	DLC	D0	D1	D2	D3	D4	D5	D6	D7
600h + node-ID	8	2Fh	25h	10h	1h	4h	0h	0h	0h

 

2. Wait until you get a response.

 

3. Write 0 checksum to checksum index.

 

COB-ID	DLC	D0	D1	D2	D3	D4	D5	D6	D7
600h + node-ID	8	23h	50h	1Fh	4h	0h	0h	0h	0h

 

4. Give a power boot for the control unit.

 

 

 

Command for 2000 series units

Use RAC (remote access and control).

5000 Series Control Units

To clear the application:

 

1. Send a following command to CODESYS node-ID:

 

COB-ID	DLC	D0	D1	D2	D3	D4	D5	D6	D7
600h + node-ID	8	23h	50h	1Fh	3h	0h	0h	0h	0h

 

Device remains in stopped state and the application is cleared from flash.

 

2. Power boot the control unit.

 

6000 Series Units

Use ApplicationLoader software, for more information see Clearing NVRAM / Files / Runtime (6107, 6112)

 

For 6505 Units, download runtime (or) from CODESYS IDE online, reset origin

 

S Series/ E Series Control Units

To clear the application:

 

1. Follow Unlocking SW protection guide to enable clearing the application

 

2. Send a following command to CODESYS node-ID:

 

COB-ID	DLC	D0	D1	D2	D3	D4	D5	D6	D7
600h + node-ID	8	23h	50h	1Fh	3h	0h	0h	0h	0h

 

Device remains in stopped state and the application is cleared from flash.

 

3. Give a power boot for the control unit.

In case a control unit is not responding to CAN messages, use the BSL pin to reset the control unit to factory settings:

 

1. Disconnect the power from the control unit.

2. Connect the BSL pin to ground

3. Power up the unit

4. The LED indicator flashes red and green alternatively (5 Hz frequency) for ten seconds after which it will flash only green (5 Hz)

    If the unit has no LED indicator, wait for 10 seconds

5. Reboot the control unit and disconnect the BSL pin from ground

6. The unit is now restored to factory settings

In case a control unit is not responding to CAN messages, use the BSL pin to remove the PLCopen application.

 

1. Disconnect the power from the control unit.

2. Connect the BSL pin to ground

3. Power up the unit

4. The LED indicator flashes red and green in (5 Hz frequency) for about ten seconds after which it will flash only green (5 Hz).

• The firmware waits for 10 -15 seconds before removing the PLCopen application. After removing the application, the default application is started.

5. Disconnect the BSL pin from ground, reboot the control unit

6. The default application is started

In case a control unit is not responding to CAN messages, use the BSL pin to remove the PLCopen application.

 

1. Disconnect the power from the control unit.

2. Connect the BSL pin to ground

3. Power up the unit

4. The LED indicator flashes red and green in (5 Hz frequency) for about ten seconds after which it will flash only green (5 Hz).

• The firmware waits for 10 -15 seconds before removing the PLCopen application.

5. Disconnect the BSL pin from ground, reboot the control unit

6. Unit starts without application
