Vme Bus Address Settings; Upper Backplane Jumper Plugs (P1) - adept technology MV User Manual

Chapter 3

VME Bus Address Settings

Each board in an Adept controller has a unique VME bus address. All boards
installed in an Adept controller by Adept at the factory have the correct address
already set when you receive the controller. If you add or change boards, you
need to check the addresses of the new boards before installing them. The address
setting for each board is covered in the chapter in this manual for that board.
Any boards that can have multiple units installed in one controller (AWC, EVI,
MI6, MI3, DIO, or EJI) must have a unique address for each of the individual
boards.

Upper Backplane Jumper Plugs (P1)

Jumper plugs are required next to any unused upper-backplane (P1) connectors
when there are boards installed in a higher number slot. For example, if there are
boards in slots 1, 2, and 4, there must be jumpers on slot 3. A connector is unused
when either:
• slot is empty (no board installed) and there are boards in higher numbered
slots
• board in adjacent slot is 2-slots wide (for example, SIO) but connects only to
the P1 connector in one slot.
On a typical controller, any required jumper plugs are factory-installed. You do
not have to do anything with jumper plugs unless you change the position of the
boards in the controller. (Refer to the following information.)
Five user-supplied backplane jumper plugs must be installed on any unused slots
in the card cage that are between slots with installed boards. For example, on the
MV-5 and MV-10 controllers, the SIO board is two slots wide but has only one set
of connectors. This leaves an empty slot that has the jumpers installed. If you
move the SIO board, you must move the five P1 jumpers.
If you install a board into a previously unused slot, you must first remove the five
jumper plugs (if any are installed); see
moved to a different slot, you may need to reinstall the five jumper plugs onto the
five pairs of jumper pins on the backplane next to the empty slot.



change the backplane jumper plugs. This requires access to the
interior of the controller, and potentially dangerous voltage may be
present if the power is not turned off.
