Porting with packed addresses

If FBs with packed I/O addresses are copied to the IM 151-7 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 151-7 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 rewired:

 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 151-7 CPU.

2. Select the menu command Tools ! Rewire.

3. Enter the desired replacements in the displayed ”Rewiring” dialog box in the

table (old address ID/new address ID).
