2.6 Mode selector switch
Use the mode switch to set the CPU operating mode.
The following table shows the position of the switch and the corresponding meaning.
Table 2- 6 Mode switch settingsThis section provides information on the terminal assignment of the individual interfaces and
the block diagram of the CPU 1513-1 PN.
24 V DC supply voltage (X80)
The connector for the power supply is plugged in when the CPU ships from the factory.
The following table shows the pin assignment for a 24 V DC power supply.
① +24 V DC of the supply voltage
② Ground of the supply voltage
③ Ground of the supply voltage for loop-through (maximum of 10 A permitted)
④ +24 V DC of the supply voltage for loop-through (maximum of 10 A permitted)
⑤ Spring opener (one spring opener per terminal)

If the CPU is supplied by a system power supply, it is not necessary to connect the 24 V
supplyThe 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
allocated either as data terminal equipment (MDI) or a switch (MDI-X).The CPU 1513-1 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 1513-1 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 1513-1 PN.
The table below shows how the MAC addresses are assigned.
