Installation, connecting up and commissioning

5.3 Connecting the CP to Ethernet

CP 343-1

38 Manual, 10/2012, C79000−G8976−C201-07

The PG / PC requires a LAN attachment, for example via a CP 1613 or CP 1411 and must

have the necessary software (for example the S71613 package or SOFTNET IE). The

TCP/IP protocol must be installed. The protocol used must then be applied to the S7ONLINE

access point.

Diagnostics

Use the diagnostic functions during commissioning and to analyze problems. The following

options are available:

● The LED displays on the CP

● Hardware diagnostics and troubleshooting with STEP 7

● Communication diagnostics with STEP 7 / NCM Diagnostics

● Static information using HW Config

● Web diagnostics

● If applicable, evaluation of the alarm block FB 54 in the user program

● Queries via SNMP

5.3 Connecting the CP to Ethernet

Connecting interface X1 to Industrial Ethernet

1. Connect the CP to Industrial Ethernet via one of the RJ45 jacks.

2. Where necessary, connect another component to the remaining free RJ45 jack.

Note

Autocrossing mechanism - effects on the connectors

For small local area networks or for attaching several Ethernet devices, a 2port switch

has been integrated on the PROFINET interface of the CP.

With the autocrossing mechanism integrated in the switch, it is possible to use a standard

cable to connect the PG/PC. A crossover cable is not necessary.

Please note the following points:

 Manual configuration

If a port is set to manual configuration and autonegotiation is disabled, the

autocrossing mechanism is also disabled for this port. Which cable you need to use

depends on the partner device (network component or end device).

In the factory, the ports are set for automatic configuration.

For more information, refer to section Network settings (Page 42)

 Con

necting switches

If you connect further switches, make sure that no ring is formed in the network.
