If the CPU is supplied by a system power supply, it is not necessary to connect the
24 V supply.The assignment corresponds to the Ethernet standard for an RJ45 plug.
● When autonegotiation is deactivated, the RJ45 socket is allocated as a switch (MDI-X).
● When autonegotiation is activated, autocrossing is in effect and the RJ45 socket is
OUTPUT_VALUE assigns the on-load factor for the current period duration. You select the
range of the field OUTPUT_VALUE of the control interface with the "Output format"
parameter.
● Output format per 100: Value range between 0 and 100
Pulse duration = (OUTPUT_VALUE/100) x period duration.
● Output format 1/1000: Value range between 0 and 1 000
Pulse duration = (OUTPUT_VALUE/1 000) x cycle duration.
● Output format 1/10000: Value range between 0 and 10 000
Pulse duration = (OUTPUT_VALUE/10 000) x cycle duration.
● Output format "S7 analog output": Value range between 0 and 27,648
Pulse duration = (OUTPUT_VALUE/27 648) x period duration.
You assign OUTPUT_VALUE directly via the control program. A new OUTPUT_VALUE is
applied at the output when the next rising edge occurs.
Setting and changing the period duration
● Permanent updating
The period duration is permanently controlled via the control interface. The MODE_SLOT
bit must be set ("1" means permanent updating); LD_SLOT must be set to value 1 ("1"
means period duration). Set the period value in the field SLOT. The unit is always a
microsecond.
– High-speed output activated: between 10 μs and 10 000 000 μs (10 s) in the field
SLOT
– High-speed output deactivated: between 100 μs and 10 000 000 μs (10 s) in the field
SLOT
– Standard output (100 Hz output): between 10 000 µs (10 ms) and 10 000 000 µs
(10 s) in the field SLOT
● Individual updating
Set the period duration in the configuration parameters. Alternatively, execute an
individual updating via the control interface. MODE_SLOT must be deleted ("0" means
individual updating); LD_SLOT must be set to value 1 ("1" means period duration). Set
the period duration value in the field SLOT. The unit is always a microsecond.
– High-speed output activated: between 10 μs and 10 000 000 μs (10 s) in the
parameters
– High-speed output deactivated: between 100 μs and 10 000 000 μs (10 s) in the
parameters
– Standard output (100 Hz output): between 10 000 µs (10 ms) and 10 000 000 µs
(10 s) in the parameters
The new period duration is applied at the next rising edge of the output.
allocated either as data terminal equipment (MDI) or a switch (MDI-X)The CPU 1511T-1 PN has a PROFINET interface with two ports. The PROFINET interface
itself has a MAC address, and each of the two PROFINET ports has its own MAC address.
The CPU 1511T-1 PN therefore has three MAC addresses in total.
The MAC addresses of the PROFINET ports are needed for the LLDP protocol, for example
for the neighborhood discovery function.
The number range of the MAC addresses is sequential. The first and last MAC address are
lasered on the rating plate on the right side of each CPU 1511T-1 PN.
The table below shows how the MAC addresses are assigned.Display PN X1 P1 R PROFINET interface X1 Port 1
