One Time Management Mode

INTRODUCTION

This document defines the procedure for customers to utilize the "One Time Management Mode" of the DX200, YRC1000 and YRC1000micro robot controllers for loading files that would otherwise require a Yaskawa authorized representative to perform. 

ADDITIONAL RESOURCES

In order for the customer to be able to load certain file types (e.g. all.prm, cmos.bin), Yaskawa must generate a one time passcode.  We "link" this pass code to a controller serial number in order to ensure the correct controller is being activated.  Once a serial number is provided, Yaskawa can generate the one time passcode. To access the serial number follow the steps below. If you have a smart pendant, see here.

First, we must ensure that you are in management mode security level or higher

Select SYSTEM INFO and then VERSION sub-menu to open the version screen

Press UTILITY to select SD Serial ID from the pull-down menu.  Please note that depending on your controller type, you will either see "CF SERIAL ID" or "SD SERIAL ID" as some controllers use compact flash while newer generations use SD cards.

A dialog notification with the SD-ID /  CF-ID of the the main CPU is shown

Record the Serial ID to send with the requested file(s). NOTE: you can record a screen shot of this window to the memory device inserted in the pendant by simultaneously pressing the "AREA" and "AUX" keys.

CONTROLLER BACKUP

In addition to the controller serial number, Yaskawa will generally request that you also send a current copy of your ALL.PRM (all parameter) file.  If other files are needed, separate guidance from your Yaskawa contact will be provided.  If you are not familiar with how to save this data, a "backup basics" article is linked above in this article.

Email the backup and serial ID to the Yaskawa authorized person you are  working with. The response from Yaskawa, will have a one-time security code that will be valid for up to 7 days.  Please follow all instructions and information offered by Yaskawa so no incorrect changes or system modifications are made.

By using this one-time code, the user assumes responsibility for and is aware that improper usage can result in unexpected operation and compromise the original safety parameters of the system! You may be required to sign and return a release form indicating you understand and agree to assume responsibility.

USING THE ONE TIME PASSWORD

If you have been provided with a new CMOS.BIN file, you will need to boot in to Maintenance Mode to load this file. To boot in to Maintenance Mode, power off the controller. Hold the MAIN MENU key on the pendant as you power on the controller. You can release the key after you hear a beep or after a few seconds have passed. All other files can be loaded in normal operations mode. 

Once again, you must ensure that you are logged in as management mode security level or higher.  Once you have logged in as a "manager", the system will now also offer you the additional optional security level of "ONE TIME MANAGEMENT MODE"

A character input key pad is shown for you to input the one-time security code emailed from Yaskawa.  Once successfully entered, the current mode will switch to "ONE TIME MANAGE MODE"

NOTE:  Depending on your controller type and software revision, you may also notice that the 3 keys displayed in the upper status bar will turn green!

CRC CHECK FUNCTION (DISABLE)

If a Functional Safety Unit (FSU) is installed, you will need to disable the CRC checksum verification process before attempting to load files.  If no FSU is installed, you will not see the option to disable CRC Checksums. You can skip this section and scroll to the next.

Disabling the CRC check function requires the user to be logged into safety password level.  Please select SETUP menu and then FUNCTION ENABLE sub-menu.  Scroll through the list of available options and toggle the option "SAVE DATA CRC CHECK FUNCTION (FSU)" from VALID to INVALID.

LOADING OF MODIFIED FILES

At this step, you are now ready to load the files provided from Yaskawa.  This will typically be an ALL.PRM file or an FD.PRM file.  Because you are logged in as a "one time manager" and have disabled any required CRC checks, the file should load in smoothly.  If there is an alarm generated, please consult the Yaskawa technician you are working with for additional guidance.

CRC CHECK FUNCTION (ENABLE)

If you previously disabled the CRC checksum function you must now reenable the function.  As a reminder, please select SETUP menu and FUNCTION ENABLE sub-menu. Toggle the option "SAVE DATA CRC CHECK FUNCTION (FSU)" from INVALID to VALID.

REBOOT

After a system level parameter has been changed, a controller reboot is required for that parameter change to take effect.  Go ahead and cycle power to the controller using the main disconnect on the controller door or use the soft CPU RESET function from the teach pendant.

Upon reboot, if an FSU is installed, the system will generate an alarm 300 [10].  This is normal and to be expected.  The alarm is the safety system telling you that a change was made but not yet acknowledged or confirmed into the safety system.  This is a fairly standard process but if you are not already familiar with how to reset the FSU, please visit the Safety Board Flash Reset knowledgebase article that is linked above.
