Communication and I/O Table Mapping 4-5
Bit 6 - This bit is used to enable/disable the module grouping feature
for the module.
Bit 0-5 - Without grouped modules - Defines the number of
configuration data bytes for the module. With grouped modules -
Defines the number of bits the module should allocate in the opened
byte.
Configuration Data
Configuration data is passed on to each I/O module using User
Parameter Data. The data is module dependant (see Appendix B).
The following table is an example of how User Parameter Data might
look with a 1734-OB2E in slot 1, 1734-IB4 in slot 2, and 1734-OE2C in
slot 3. All modules in this example use Configuration Data.
Bit Value Description
0 Grouped module disabled
1 Grouped module enabled
IMPORTANT
Using your PROFIBUS configuration tool, it is
possible to select modules with no configuration
data. If you use this type of module, the
configuration data for that module will be a default
value. (See Appendix B.)
