The front cover is pluggable. If necessary, you can take off the front cover or replace the
front cover during runtime (RUN). Removing or replacing the front cover does not affect the
CPU in operation.
To remove the front cover from the CPU, follow these steps:
1. Flip up the front cover until the front cover stands at a 90° angle to the front of the
module.
2. In the top section of the front cover, press on the anchor(s): Two anchors with
CPU 1515R-2 PN, CPU 1517H-3 PN. One anchor with CPU 1513R-1 PN.
At the same time, pull the front cover towards you and off.
The view in the figure below is an example of CPU 1515R-2 PN.f you remove or attach the front cover during operation, personal injury and damage can
occur in hazardous areas of zone 2.
Always disconnect the R/H-CPU from the power supply before you remove or attach the
front cover in hazardous areas of zone 2.When installing the coding element, you must take into account the supply voltage of the
system power supply and load power supply: 24 V DC, 24/48/60 V DC or 120/230 V AC/DC
Only install the coding element with switched-off voltage.
You must insert the coding element in such a way that the power connector matches the
power supply module in terms of voltage.2. Orient yourself using the red marking on the coding element.
3. The coding element has 3 red markings. Turn the coding element in such a way that one
of the 3 red markings corresponds to the voltage indicated on the connector.
4. Insert the coding element into the back side of the power cable connector, until you hear
it click into place. The figure below shows you how to insert a coding element into a
power cable connector for 24 V DC.You use firmware files to update the firmware of the CPUs, displays and the IO devices (for
example for new functions). Th

The options for performing a firmware update are as follows:
● Online in STEP 7 via Online & Diagnostics
● Online in STEP 7 via accessible devices (PROFINET)
● Via the SIMATIC memory card: For CPU and display only
The table below gives an overview of the various options for a firmware update.The options for performing a firmware update are as follows:
● Online in STEP 7 via Online & Diagnostics
● Online in STEP 7 via accessible devices (PROFINET)
● Via the SIMATIC memory card: For CPU and display only
The table below gives an overview of the various options for a firmware update.Proceed as follows to perform a firmware update online via STEP 7:
1. Select the module in the device view.
2. Select the "Online & diagnostics" menu command from the shortcut menu.
3. In the "Functions" folder, select the "Firmware update" group.
For a CPU, you can select whether you want to update the CPU or the display.
4. Click the "Browse" button to select the path to the firmware update files in the "Firmware
update" area.
5. Select the correct firmware file. The table in the firmware update area lists all modules for
which an update is possible with the selected firmware file.
6. Click the "Run update" button. If the module can interpret the selected file, the file is
downloaded to the module. If you need to change the CPU operating state, STEP 7
prompts you to do so with dialogs.
Note
Updating PROFINET IO devices with system redundancy S2
The R/H system remains in the RUN-Redundant system state if you update an IO device
with system redundancy S2.The "Run firmware after update" check box is always selected.
Once the files have been successfully loaded, the CPU accepts the firmware and operates
with the new firmware.he SIMATIC memory card
Proceed as follows to perform a firmware update using the SIMATIC memory card:
1. Insert a SIMATIC memory card into the SD card reader of your PG/PC.
2. To store the update file on the SIMATIC memory card, select the SIMATIC memory card
under "Card reader/USB memory" in the project tree.
3. Select the "Card Reader/USB memory > Create firmware update memory card"
