Unique Logical Address is used by the 6200 series
programming software to determine the A16 base address of
the PLC-5/VME processor ’ s registers..
The VMEbus contains several daisy-chained control signals. Almost all
VMEbus backplanes contain jumpers for these control signals to allow
systems to operate with empty slots. Failing to install these jumpers
properly is a common source of problems in configuring a new
VMEbus system.
There are five jumpers per VME slot, one for each of the four bus-grant
arbitration levels and one for the interrupt-acknowledge daisy chain.
Depending on the backplane manufacturer, the jumpers can be on the
rear pins of the J1 connector or alongside it on the front of the backplane.
The PLC-5/VME processor uses two slots. Based on what is in the VME
slot, install or remove the backplane jumpers as follows:
VME Slot Content Five Backplane Jumpers
PLC-5/VME processor’s left slot Remove
PLC-5/VME processor’s right slot Install
Empty slot Install
