5.6 Hardware configuration - Ethernet PG/OP channel
The CPU 315-4PN23 has an integrated Ethernet PG/OP channel. This channel allows
you to program and remote control your CPU. The PG/OP channel also gives you access
to the internal web page that contains information about firmware version, connected I/O
devices, current cycle times etc. With the first start-up respectively after an overall reset
the Ethernet PG/OP channel does not have any IP address. For online access to the
CPU via Ethernet PG/OP channel valid IP address parameters have to be assigned to
this by means of the Siemens SIMATIC Manager. This is called "initialization".
1.
Install your System 300S with your CPU.
2.
Wire the system by connecting cables for voltage supply and signals.
3.
Connect the Ethernet jack of the Ethernet PG/OP channel to Ethernet
4.
Switch on the power supply.
ð
After a short boot time the CP is ready for communication. He possibly has no
IP address data and requires an initialization.
The initialization via PLC functions takes place with the following proceeding:
Determine the current Ethernet (MAC) address of your Ethernet PG/OP channel.
This always may be found as 1. address under the front flap of the CPU on a sticker
on the left side.
You get valid IP address parameters from your system administrator. The assignment of
the IP address data happens online in the Siemens SIMATIC Manager starting with ver-
sion V 5.3 & SP3 with the following proceeding:
1.
Start the Siemens SIMATIC Manager and set via
‘Options
è
Set PG/PC interface’
the access path to
‘TCP/IP -> Network card ....’
.
2.
Open with
‘PLC
è
Edit Ethernet Node n’
the dialog window with the same name.
3.
To get the stations and their MAC address, use the [Browse] button or type in the
MAC Address. The Mac address may be found at the 1. label beneath the front flap
of the CPU.
4.
Choose if necessary the known MAC address of the list of found stations.
5.
Either type in the IP configuration like IP address, subnet mask and gateway.
6.
Confirm with [Assign IP configuration].
ð
Direct after the assignment the Ethernet PG/OP channel may be reached online
by these address data. The value remains as long as it is reassigned, it is over-
written by a hardware configuration or an factory reset is executed.
