Configure a Discrete Input/Output Module
After you "accept" a module into the slot, a screen like this appears:
S:1 I:16

Number of

this module
Assign I/O References
Specify the references to be used by the module. For most applications, you can simply have the
Bus Interface Unit assign the next available references in that memory type. Alternatively, you can
enter specific references for the module.
A. To assign the next available references, just press F4 (entr).
B. If you want to change to another type of I/O table, press F3 (toggle).
C. If you want to assign specific references, enter the starting address. Press F4 (entr).
For most applications, all module references should fall within the network map
configured for the Bus Interface Unit. For local control, a module can be
configured outside the BIU network map.
In addition, each data type (I, Q, AI, AQ) has a total of 256 bytes allocated
within the BIU. So for each data type, all references must be located within a
256-byte range. For example, if the starting address for output data configured
for the Bus Interface Unit was Q01024, all module outputs would need to be
located between Q01024 and Q03072. (Discrete references are assigned on byte
boundaries).
Module references are automatically assigned by the Bus Interface Unit based on its configured
data addresses and the number of points appropriate for the module type.
To edit the module's configuration, press F4 (zoom).
