5.4 Changing a device
You can change the device type of a configure CPU or module. From Device configuration,
right-click the device and select "Change device" from the context menu. From the dialog,
navigate to and select the CPU or module that you want to replace. The Change device
dialog shows you combatibility information between the two devices.
Note
Device exchange: replacing a V3.0 CPU with a V4.0 CPU
You can open a STEP 7 V12 project in STEP 7 V13 and replace V3.0 CPUs with V4.0
CPUs. You cannot replace CPUs that are from versions prior to V3.0. When you replace a
V3.0 CPU with a V4.0 CPU, consider the differences (Page 995) in features and behavior
between the two versions, and actions you must take.
If you have a project for a CPU version older than V3.0, you can upgrade that project first to
V3.0 and then upgrade the V3.0 project to V4.0.
