Unit settings
This Special I/O Unit is configurable with settings made in a dedicated DM
area. The assigned DM area depends on the Machine number setting:

Default mode
The first word in the DM area allocated to the Unit will be indicated by DM m,
the last word by DM m+19.
The values entered in the Unit settings area are only transferred to the Unit
during initialisation, i.e. at power on and at Special I/O Unit restart. The Unit is
said to operate in Default Mode when the values of all Unit settings are zero.
DM m ~ DM m+15 are reserved for CORT21-V1. DM m+16 ~ DM m+19 are
used to set any baud rate defined by CAN.

Baud Rate Configuration
The standard CAN baud rates are selectable via the DIP-switches at the front
of the Unit (see section 2-1-4). However, if a different baud rate is required, it
is possible to configure this via the Unit settings. The Unit settings only
overrule the DIP-switch settings when all the configured values are within the
specified ranges. By default, these Unit settings are zero and therefore the
DIP-switches determine the baud rate.
The Unit settings directly configure the hardware registers of the CAN
interface that determine the baud rate. Incorrect settings will cause improper
functioning of the CAN interface. It is advised to users with no CAN
experience to contact the distributor for setting the correct values.
The table below lists the DM words for configuration of the baud rate.
