Scale the data when reading or writing an external register to an internal one.
A calculation result is restricted to the following range:
Signed: -32768 to 32767
Unsigned: 0 to 65535
These new error codes has been added:
No. Code
1 31h Modbus mapping missmatch
2 32h Access to a duplication register
No. Internal register
1 0000h (Initial value)
2 0001h to FFFFh
3 0001h to FFFFh
When two or more internal registers in which values differ are in the same
external register, both are considered incorrect.
In the same way two or more internal registers couldn't be allocated to one
external register.
When an external register and retry a existing register overlap, access to the
register is not available.
Moreover, when the overlapping existing register is a double word parameter,
access of the register used as a pair is also forbidden.
Example:
External register = 1216 (overlaps with higher rank of existing register: 1216h
= A020.)
Internal register = 1201h (existing register: 1201h = A001)
Address 1216h will be associated with two parameters, A020 and A001, As
this is not possible only the modbus mapping setting is used and it means that
neither lower or higher rank of A020 could be accessed.
Is not possible to use a double word or a none existing register as internal reg-
ister.
