Changing the Size of the I/O Map
Introduction The default size of the I/O Map and your options vary, depending on whether or not
your Processor Adapter supports an I/OBus network.
Processors For
I/O Bus
Networks With I/OBus, an I/O Map table is used to define the number, location, and type of
I/O devices on the network bus.

Processors Other Processor Adapters only use the I/O Map for local I/O. The default of 32
words is sufficient for any Momentum I/O base. Depending on the requirements of
your I/O base, you may be able to reduce the number of words to the minimum, 17,
in order to increase the size of the full logic area.
