Two FW files are available for updating the CP:
- 6GK7 243‑5DX30‑0XE0
V01.03.04.upd must be used if the CM 1243‑5 is plugged in next
to a 1200-CPU with FW version V3 or lower.
- 6GK7 243‑5DX30‑0XE0
V01.03.04_V4CPU.upd must be used if the CM 1243‑5 is plugged in
next to a 1200-CPU with FW version V4.
CM 1243‑5 modules with a FW version below 1.3.3
must be updated using a memory card.
Updating the firmware:
not use the Windows formatting program to newly format the Memory Card.
If a Siemens Memory Card is newly formatted with the Windows formatting
program, the Memory Card can no longer be used by a S7-1200 CPU.
install the CP firmware update, please proceed as follows:
- Insert an
empty SIMATIC MC 24-MB Memory Card into a SD card reader connected
to your computer.
If you use a SIMATIC Memory Card which already contains a user
program or any other firmware update, you must first delete the file
"S7_JOB.S7S" and all folders (e.g. "SIMATIC.S7S"
or "FWUPDATE.S7S"), before you can download the firmware
update. You can use the Windows Explorer to display the contents of
the Memory Card and to delete the file and the folders.
Do not delete the hidden files
"__LOG__" and "crdinfo.bin" on the memory card.
The files "__LOG__" and
"crdinfo.bin" are necessary to be able to use the card. If
these files are deleted, the card can no longer be used by the CPU.
the CP firmware update. Unpack the file to the root directory of the
SIMATIC Memory Card. When the extraction is completed, the root
directory of the memory card will contain the directory
"FWUPDATE.S7S" and the file "S7_JOB.S7S".
Before you install the firmware update please ensure that the
CPU is not executing an active process.
installation of the firmware update lets the CPU enter STOP mode, which
can have repercussions on the online process or the running of a
machine. Unexpected running of the process or the machine can result in
lethal or serious injury and/or damage to property.
you insert the Memory Card, please make quite sure that the CPU is
offline and in a safe state.
- Insert the Memory Card
into the CPU. If the CPU is in RUN, it will go to STOP mode. The
maintenance LED (MAINT) will blink to indicate that the Memory Card
must be evaluated.
- Start the CPU again
to start the firmware update. Alternative methods to restart the CPU
are to change from STOP to RUN, or to perform an overall reset
(MRES) in STEP 7.
After the CPU has been restarted the firmware update will be copied
to the load memory. The RUN/STOP LED will blink green and yellow to
indicate that the update is being copied. If the RUN/STOP LED
remains permanently lit and the MAINT LED blinks, the copy process
is completed. You can now remove the Memory Card.
you have removed the Memory Card, restart the CPU again to load the
new firmware (either by switching it on, or
by another method for restarting).
user program and the hardware configuration are not affected by the
firmware update. When the CPU is switched on it will enter the configured
