New functions of the CPU in firmware version V2.8
New functions Applications
SIMATIC Industri- The Linux component was updated
al OS to the SIMATIC Industrial OS oper-
ating system with firmware version
V2.8.4 on the CPUs 1518(F)-4
PN/DP MFP (multifunctional plat-
form).
IP forwarding IP forwarding forwards IP data
through the CPU from one IP sub-
net to another IP subnet.
During IP forwarding, the CPU
automatically creates an IP route
table from the IP configuration in
STEP 7.
Direct data ex- In the case of direct data exchange,
change the CPU cyclically provides user
data from the I/O area to one or
more other CPUs.

Customer benefits
This expansion allows you to imple-
ment larger and more extensive
applications with the CPUs.
Customer benefits
Siemens-administered Linux distribu-
tion: All necessary Linux updates
including security updates are veri-
fied and made available by Siemens.
• Simplified integration of devices
for remote access, e.g. for diag-
nostics during remote mainte-
nance or firmware update
• Simple access from the control
level to the field level for configu-
ration and parameter assignment
of devices
Example: You can access the Web
server of a drive connected to the
X1 interface of the CPU from a
computer connected to the X2 in-
terface of the CPU.
The "Direct data exchange" function
enables deterministic, isochronous
I/O communication between multiple
S7-1500 CPUs.
