 Input Size: The input size must be at least 68 Words (136 Bytes). It must be
large enough to accommodate the status information required by the module,
which is 68 Words (136 Bytes) plus the number of PROFIBUS output data.
The user can increase the size of this area using the size of each Output
module connected. The PROFIBUS Output area starts with Word 68 (Byte
136).
 Output Size: The output size must be at least 2 Words (4 Bytes). It must be
large enough to accommodate the command information required by the
module, which is 2 Words (4 bytes), plus the number of PROFIBUS input
