Flexible Mode
Section 4-6
When the Option Board is unable to execute one of the write parameter
instructions, it adds an error value and the failed element index to the result
data. Changing Option Board parameter elements 915.9 - 915.12 for exam-
ple:
Has the following result:
Note that the error number is followed by the element number where the
change instruction failed. I.e. The changes to Option Board parameter ele-
ments 915.9 and 915.10 were carried out successfully. The attempt to change
915.11 failed and changes to subsequent elements (915.12) were not carried
out.

Flexible Mode
The Flexible device profile lets you operate the Inverter using the Modbus
registers directly. Parameters P160 - P169 and P170 - P179 can be used to
map Modbus registers into the cyclically exchanged process areas. User
parameters P160 - P169 configure the output process area mappings where
parameters P170 - P179 configure the input process area mappings.
