The shortcut menu commands "Modify > Monitor from here" and "Modify > Monitor selection"
will not be available until firmware of S7-400 is updated.
Programming of NTP servers with the system function block "T_CONFIG"
For a CPU of the S7-1500 module with the firmware version V1.8, up to four NTP servers can
be configured program controlled with the "T_CONFIG" instruction for time synchronization
via the Ethernet / PROFINET interface. For this purpose, the address data of the NTP servers
is stored in the system data type (SDT) "IF_CONF_NTP".
This requires that time synchronization is enabled via NTP in STEP 7 and at least one NTP
server is configured. The NTP server or servers configured in STEP 7 do not have to be
identical with the NTP servers that were programmed in the SDT "IF_CONF_NTP". The NTP
servers stored in the SDT "IF_CONF_NTP" overwrite the data in the STEP 7 configured NTP
server during runtime.
Die firmware version V1.8 for S7-1500 CPUs is available with STEP 7 V13.0 SP1 Update 4.
2.1 Improvements in Update 4
Update 4 contains the following improvements and changes:
Working with the TIA Portal
Stability when working with the TIA Portal has been improved, partly based on the feedback
from returned crash reports.
Instructions "TCON, TSEND_C, TRCV_C" (S7-1200 and S7-1500)
In addition to the causes listed in the online help, the value W#16#80C4 from STATUS
(temporary communications error) can have the following causes:
● The connection cannot be established because firewalls for the required ports situated on
the connection path are not enabled.
Instruction "D_ACT_DP: Enable/disable DP slaves" (S7-1500)
● Contrary to the description in the online help, the following applies to the disabling / enabling
of the IE/PB Link PN IO type of gateway:
You cannot disable/enable an IE/PB Link PN IO type of gateway using the instruction
"D_ACT_DP". If you nevertheless use D_ACT_DP on the said gateway, the CPU returns
the value W#16#8093 "No hardware object that can be activated or deactivated belongs
to the address specified in LADDR."
● As a supplement to the description in the online help, the following applies to firmware as
of version V1.8 of the S7-1500 CPUs:
You can use the "D_ACT_DP" instruction to disable/enable DP slaves that are connected
to an IE/PB Link PN IO type of gateway.
Instruction "GET_IM_Data: Read identification and maintenance data" (S7-1500)
Contrary to the information in the online help, the error code "80C3", rather than the error code
"807F", is shown. The description for the error code "807F" provided in the information system
is also valid for the "80C3" error code.
Keyboard operation in comparing SCL blocks
In the Comparison editor, the following keyboard operations are now also available for SCL
blocks:
Function Keyboard shortcut
Navigate to the next point of use of the selected operand
<Ctrl+Shift+G>
Navigate to the previous point of use of the selected
operand
<Ctrl+Shift+F>
Parameter transfer
Note the following for parameter transfer between blocks with optimized access and blocks
with standard access:
Note
Parameter transfer between blocks with optimized access and blocks with standard access
If, during a block call, structures are transferred to the called block as in/out parameters (InOut),
they are transferred by default as pointers (Call by reference).
However, this does not apply if the two blocks have different optimization settings: If one of
the blocks has the property "Optimized access" and the other block has the property "Standard
access", all parameters are always transferred as copies (Call by value).
This means that the called block always works with the copied values. During the processing
of the block, these values may possibly be changed and copied back to the original operand
after the processing of the block call.
This can lead to problems if the original operands are changed by asynchronous processes,
such as by HMI access or interrupt OBs. If the copies are copied back again to the original
operands after the block processing, the changes made asynchronously to the original
operands are overwritten.
You can avoid this by setting the same access type for both blocks or by allowing the
asynchronous access to be written only to a separate memory area and then copying this area
synchronously when the time is appropriate.
Know-how protection
The know-how protection has to be removed for blocks that were protected against
unauthorized access by an older version of the TIA Portal and now have to be opened or
changed. This can subsequently be reset.
Testing with program status
The monitoring of code blocks (STL, LAD, FBD, SCL) with a CPU from the S7-400 series has
been improved and no longer results in STOP.
Note in each case that only interconnected opened networks can be monitored. A closed
network interrupts the monitoring.
The shortcut menu commands "Modify > Monitor from here" and "Modify > Monitor selection"
will not be available until firmware of S7-400 is updated.
Programming of NTP servers with the system function block "T_CONFIG"
For a CPU of the S7-1500 module with the firmware version V1.8, up to four NTP servers can
be configured program controlled with the "T_CONFIG" instruction for time synchronization
via the Ethernet / PROFINET interface. For this purpose, the address data of the NTP servers
is stored in the system data type (SDT) "IF_CONF_NTP".
This requires that time synchronization is enabled via NTP in STEP 7 and at least one NTP
server is configured. The NTP server or servers configured in STEP 7 do not have to be
identical with the NTP servers that were programmed in the SDT "IF_CONF_NTP". The NTP
servers stored in the SDT "IF_CONF_NTP" overwrite the data in the STEP 7 configured NTP
server during runtime.
Die firmware version V1.8 for S7-1500 CPUs is available with STEP 7 V13.0 SP1 Update 4.

performed on the CPU.
Affected MLFBs:
● 6AV6645-0EB01-0AX1
● 6AV6645-0EC01-0AX1
● 6AV6645-0EF01-0AX1
● 6AV6645-0GB01-0AX1
● 6AV6645-0GC01-0AX1
● 6AV6645-0GF01-0AX1
Use of the Mobile Panel 277F IWLAN in the industrial environment
To avoid communication problems between the HMI device and access point, please observe
the following:
IWLAN planning: Wireless connection between the HMI device and access point.
● Wireless field planning needs to be carried out. Radar influences need to be taken into
consideration for channels requiring Dynamic Frequency Selection (DFS).
● Avoid radio frequency interference from other devices, such as hand-held devices with
Bluetooth or WLAN function.
● For adjacent access points, use data channels that are separated by at least one wireless
channel (e.g. 36 and 44 rather than 36 and 40).
● Do not place several access points in the immediately vicinity of one another. Spacing of
at least 5 m is recommended.
● For the Mobile Panel 277F IWLAN, use the "Software retry number" 15 instead of the default
value 3.
Use the "rapid roaming" function with iPCF-MC
● Always use iPCF or iPCF-MC (rapid roaming) for PROFIsafe communication.
● Use the same SSID for all access points.
● The "Background scan" should be switched off on the HMI device (“Background scan
interval” for the HMI device = 1 (default value)).
● Use the same "Management channel" and different, non-overlapping "Data channels" for
all access points.
