Data addressing and offset:
The CFW-08 data addressing is realized with an offsetequal
to zero, that means that the address number is equal to the
register number. The parameters are available from address
0 (zero) on, whilst the basic variables are available from
address 5000 on. In same way, the status bits are made
available from address 0 (zero) on and the control bits are
made available from address 100 on.
Table below shows the addressing of bits, parameters and
basic variables:
