Clearing memory from an Allen Bradley SLC 500 Including Passwords

snapshot-3.pngToday we are going to show you how to clear the memory in your SLC 500 controller. Before you begin, make sure you understand that clearing them memory in your processor will set it completely back to factory defaults including erasing all programs, passwords, and setting communications parameters back to default.

To start, disconnect the power from your processor, remove the processor from the rack, disconnect the battery, and remove any memory modules.

Then on the back of the processor find the GND & VBB points then use a small screwdriver and short those two points together for 60 seconds making sure that you are making good metal to metal contact.
