Porting with Packed Addresses
If FBs with packed I/O addresses are copied to the IM 151/CPU, the packed
addresses there can no longer be assigned to the I/Os of the I/O modules locally
because the CPU of the IM 151/CPU cannot work with packed addresses. This
requires rewiring of the corresponding FBs. Rewiring corresponds to ”unpacking”
the addresses.

Rewiring
The following blocks and address IDs can be reassigned:
 Inputs, outputs
 Memory markers, timers, counters
 Functions, function blocks
Proceed as follows to rewire the signals:
1. In SIMATIC Manager, select the “Blocks” folder, which contains the blocks with
the packed addresses that you want to port to the IM 151/CPU.
2. Choose Options Rewire.
3. Enter the desired replacements in the displayed “Rewiring” dialog box in the
table (old address ID/new address ID).
