If the parameter "ForceUserConfiguration" is set to 0 then the module calculates
automatically a timeout value by the RPI (Requested Packet Interval). The
calculated watchdog results to 2 x the RPI (+/- 5ms). The smallest watchdog
value is 15 ms. The module will round the watchdog to a multiples of 5 ms.
WATCHDOG_TIME (ms) = MAX ( 2 * RPI ; 15 ) (+/-5ms)
If the parameter "ForceUserConfiguration" is set to 1 the module will take the
watchdog value from the configuration array. Make sure that the watchdog is not
smaller than the RPI. The module will also round the watchdog to the next
multiple of 5ms.
Number of Valid Configuration Bytes
This parameter holds the number of valid configuration bytes that define
PROFIBUS Input/Output modules.

The PS69-DPS PROFIBUS-DP Slave offers a flexible, modular composition of its
I/O data. This means that parts of the input and output image can be viewed as
single modules. The master can put the different modules from the PROFIBUS-
DP Slave to different locations in its I/O area. The individual configured modules
are mapped linearly in the I/O area of the Slave module. It is possible to
configure up to 24 I/O modules. A module is defined by a Module Type and its
Module Length:
