Changing A Device; Adding Modules To The Configuration - Siemens SIMATIC S7-1200 Manual

Easy to create the device configuration

5.3 Changing a device

5.3 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 345) 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.

Adding modules to the configuration

Use the hardware catalog to add modules to the CPU:
● Signal module (SM) provides additional digital or analog I/O points. These modules are
connected to the right side of the CPU.
● Signal board (SB) provides just a few additional I/O points for the CPU. The SB is
installed on the front of the CPU.
● Battery Board 1297 (BB) provides long-term backup of the realtime clock. The BB is
installed on the front of the CPU.
● Communication board (CB) provides an additional communication port (such as RS485).
The CB is installed on the front of the CPU.
● Communication module (CM) and communication processor (CP) provide an additional
communication port, such as for PROFIBUS or GPRS. These modules are connected to
the left side of the CPU.
To insert a module into the device configuration, select the module in the hardware catalog
and either double-click or drag the module to the highlighted slot. You must add the modules
to the device configuration and download the hardware configuration to the CPU for the
modules to be functional.
