erasing memory from SLC 5/01

hi, i am reusing a slc 5/01 from a medar control panel.
medar has put a master password on the slc 5/01 so i cannot
go online or download anything. is there a way to erase the
exising password and program on the 5/01 and download a whole new one?
 
E42136511: The ladder logic project appeared to download but got an error right after the download appeared to complete.
Problem: Init_initial driverfailed codefailed_code –1 error when downloading Cause: Unknown at this time. Cure: SUGGESTION:
1. Short out vbb & gnd (Clearing the memory to the processor, Instructions below)
2. After powering back up, reconfigure driver, in this scenario, it was ab_df1 driver
3. Go to rslogix500 , open project to download, go to tools, options, sys communications in this scenario( verify ab_df1 / node =1)

Select Download, it should be successful! Prevention:
HOW TO CLEAR THE MEMORY TO A SLC PROCESSOR:
To Clear the memory on an AB SLC 500 processor:

For 5/03 and 5/04 Processors:
1) Power down processor.

2) Pull processor out of rack and disconnect battery cable.

3) Find the VBB and GND solder pads on the back side of the processor (5/03 - on the back side of mother board where the battery would be located. 5/04 - on the back side of mother board approx. 1 inch from the back connector edge of the mother board and about centered from the top/bottom of mother board.)

4) Using something metal (a paper clip will do), short the VBB and GND terminals for 60 seconds.

5) Reconnect battery and insert processor into rack.

6) Power up processor.

(See AB Publication 1747-6.2 SLC 500 Modular Hardware Style Installation and Operation Manual, Troubleshooting Chapter, "Returning Processor to Initial Factory Conditions" for pictures of mother board and locations of VBB and GND solder pads.)

For 5/01, 5/02, and Fixed I/O Processors:
1) Power down processor.

2) Pull processor out of rack and disconnect battery cable or battery jumper (if it has one installed.) For 5/01 4K processors and 5/02 processors (which do not have the on board capacitor to backup RAM memory), wait 60 seconds and skip to step 5.

3) Let it sit for about a week or two (possibly up to a month) on a shelf somewhere. (All Fixed I/O units and 5/01 1K processors have an on board capacitor to backup RAM memory which need to drain to clear memory.)
or
Jumper pins 14 and 28 of chip U3 (or IC3 -- as labeled on the processor), but this is difficult to explain over the telephone, so I do not recommend even mentioning it. It is documented in their hardware manual (supposedly), so direct them there or have them contact hardware support.

5) Reconnect battery or battery jumper and insert processor into rack.

6) Power up processor.


You will know the manual clear memory attempt was successful if the processor's fault light is blinking
at a rate of 2 blinks per second when it is re-inserted back into the rack and the power is turned on.
On a WHO ACTIVE screen the software will show 5/0? DEFAULT (i.e. processor type / project name=DEFAULT).
The processor is now in default mode and a project can be downloaded to it.
 
thank you very much for the reply
the easy way looks to take the longest, but i will try it
thanks again
 
reset memory to fac/set

Summary of Technote Information:

--------------------------------------------------------------------------------



The following procedure can be used to restore defaults to a Micrologix or SLC-500 processor
when the software requests a password. RSLOGIX 500 v3.01.09.02 or greater must be
used. APS and AI 500 software do not support this procedure.


NOTE: By following this procedure the program in the
Processor will be erased.

1) When prompted for the password enter MLCLRMEM , using the keypad of a
telephone you must translate this into its numeric equivalent of " 65257636 "

2) You will be prompted to confirm the clearing of the processor ladder logic program.



3) Once this is confirmed the processor will return to a default
( Out of the Box ) state with it's default program.


The software will then return offline to it's default screen.
