For some fieldbus connections (all Slave modules) the base addresses are mapped in the memory region upper
DFFFF(hex). So this modules must be ordered with other base addresses. The same situation takes place if more
than two or more master modules of same type are used (for more see note below). The order numbers for the
modules are:
