14.11 Module reset
When this parameter is set (On), the module performs a warm reset. When the reset
has been completed and the module is performing its initialisation routines, this
parameter will be cleared to zero (Off). The drive, and any other modules fitted to the
drive will not be affected by the reset.
14.12 Use saved option parameters
If valid configuration parameters have previously been stored in the SI-Interbus flash
memory (see
MM.031 ), these values can be restored into the host drive parameters by
setting Pr MM.033 to On.
When the configuration parameter values have been uploaded to the host drive
SI-Interbus will reset and re-configure using the updated parameter values.
This feature allows a pre-configured SI-Interbus module to be installed into a host drive
without losing the SI-Interbus configuration.
14.13 Data compression enable
By default, the SI-Interbus uses 32 bits for each data channel, even if the target
parameter in the drive is a 16-bit parameter. This strategy (known as casting) ensures
that the cyclic data transmitted over the Interbus network is kept aligned with memory
locations in 32-bit PLCs. When cyclic data compression is enabled (Pr
MM.34 = On),

If the mapping configuration size has changed (Pr MM.005 Interbus Data Format ), then
the module reset is insufficient to fully initialise the Interbus network and after saving
parameters, the module must be power-cycled.
