Refer to the configuration example to understand how and where to enter this
data.
Full Format
The full format consists of the flags byte and four parameters for each of the
eight slots. The module key parameter is the same for the full format as defined
by the condensed format, but adds three more parameters for each slot.
Use the full format to:
provide Safe State values for output points
send FLEX I/O module configurations once (when you send parameters)
instead of every poll
configure data sizes to reduce the size of data required during run mode You
must configure all eight slots.

ARRAY
Flex Module Configuration. Word array of size Config Size.
1 Only bits 0 to 12 are used. Bits 13 to 15 must be zero except when keying an
empty slot where 0FFFFh is used.
2 Each of the two sizes can range from 0 to 15 words but when combined cannot
exceed 15 words total.
There are some possible configurations of FLEX I/O modules that would exceed
the user parameter area of 237 bytes. Be aware of the totals of the words and
modules you are using.
