n
Direct DX transition - if this parameter is activated, the integrated PROFIBUS DP
master, if activated by VSC, shows the following behavior:
–
As long as a DP slave is in Data Exchange, i.e. in the DP slave standard diag-
nostic data byte 0, bit 1 and byte 1, bit 0 have the status 0, this DP slave is
directly taken from the DP master in Data Exchange. The transition happens
without a
SetPrm
- and
CheckConfig
telegram was being sent to the DP Slave.
–
When a DP slave is taken to Data Exchange, the outputs remain active and are
not deactivated.
–
If the CPU goes from RUN to STOP, the DP master is deactivated for at least the
duration of the
Response monitoring time
, which is to be set in the PROFIBUS
parameters. Afterwards, the DP master becomes active again and takes the DP
slaves back to Data Exchange. When the DP master transitions to the inactive
state, the output data of the DP slaves are not zeroed nor deactivated. Standard-
compliant DP slaves automatically will switch off the outputs or zero them if they
do not receive DE telegrams from the master during the
Response monitoring
time
.
–
If the power supply of the CPU fails, the outputs of the DP slaves are not zeroed
and not deactivated. Standard-compliant DP slaves automatically will switch off
the outputs or zero them if they do not receive DE telegrams from the master
during the
Response monitoring time
.
n
PN MultipleWrite
–
In the activated state, parameter record sets are combined at PROFINET to one
or more Ethernet frames during the connection setup. This speeds up the connec-
tion setup, since a separate Ethernet frame is not used for each parameter record
set.
n
Free Module Mapping
–
When activated, you can use your CPU in different hardware variants.
–
You specify the mapping at runtime with record set 0x7F.
n
Reduced PDU size
–
When activated, the PDU size is reduced accordingly.
–
For some protocols, some configuration tools require a reduced PDU size. For
example, in the Siemens TIA portal for variable forcing, the PDU size must be
reduced. For the processing of single steps at several breakpoints, the PDU size
must also be reduced.
n
When activated, you have access to the interface or the corresponding communica-
tion protocol.
n
By default, there is no access restriction.
