Application

The CP 343−1 Lean communications processor is designed for operation in a SIMATIC S7-300 programmable logic controller. It allows attachment of the S7−300 to Industrial Ethernet and supports PROFINET IO.

A 2-port switch with autocrossing, autonegotiation and autosensing was integrated in the CP for simple integration in a line or for attaching a further Ethernet device.

Services

The CP supports the following communication services:

SPROFINET IO device

Integration of the SIMATIC S7−300 programmable controller over the CP as intelligent PROFINET IO device.

SS7 communication and PG/OP communication

−PG functions (including routing)

−Operator control and monitoring functions (HMI)

−Server for data exchange on S7 connections configured at one end only without communication blocks on the S7-300 / C7-300 station

SS5 compatible communication with

−SEND/RECEIVE interface over ISO-on-TCP, TCP and UDP connections

−Multicast over UDP connection

The multicast mode is made possible by selecting a suitable IP address when configuring connections.

−FETCH/WRITE services (server; corresponding to S5 protocol) via ISO-on-TCP connections and TCP connections;

The addressing mode can be configured for FETCH/WRITE access as the S7 or S5 addressing mode.

−LOCK/UNLOCK with FETCH/WRITE services;

Release 03/2007

C79000-G8976-C198-04

1 Properties / Services

STime-of-day synchronization over Industrial Ethernet using the following configurable modes:

− SIMATIC mode

The CP receives MMS time frames and synchronizes its local time and the time of the CPU (accuracy approx. +/− 1 second);

or

−NTP mode (NTP: Network Time Protocol)

The CP sends time-of-day queries at regular intervals to an NTP server and synchronizes its local time of day and the time of the CPU (accuracy approx. +/− 1 second).

STime of day for the diagnostic buffer

If a time master exists (using the NTP or SIMATIC mode), the time for the CP-internal diagnostic buffer is synchronized over the LAN (accuracy approx. +/− 10 ms)

SAddressing using a factory-set MAC address

The CP can be reached over the default MAC address to allow an IP address to be assigned.

SSNMP Agent

The CP supports data queries over SNMP in version V1 (Simple Network Management Protocol) according to the MIB II and LLDP MIB standard.

You will find more information on MIB in the manual “Commissioning PC Stations” on the SIMATIC NET Manual Collection or at the following SIMATIC NET Internet page:

http://support.automation.siemens.com/WW/view/en/15177711

SIP configuration

You can configure how and with which method the CP is assigned the IP address, the subnet mask and the address of a default router.

It is also possible, as an alternative, to assign the connection configuration to the CP using STEP 7 or using a block interface in the user program (FB55: IP_CONFIG) (see /Part A/).

SWeb diagnostics

With the aid of Web diagnostics, you can read out the diagnostic data from a station connected over the CP to a PG/PC with an Internet browser.

Configuration

It is possible to download the configuration data to the CP over MPI or LAN/Industrial Ethernet. You require STEP 7 with NCM S7 for Industrial Ethernet (NCM IE) with the following version:

Table 1-1

Version STEP 7 / NCM IE	Functions of the CP
V5.2 or higher	The range of functions of the CP 343−1 Lean (CX00) can be
	configured.
V5.4 or higher	Requirement for configuring the full functionality of the
	CP 343−1 Lean (CX10 with firmware V1.0) including PROFINET
	IO.
V5.4 Service Pack 2 *)	Requirement for configuring the full functionality of the
	CP 343−1 Lean (CX10 with firmware V2.0) including Web
	diagnostics.

*) To use the CP with V5.4 Service Pack 1, you will need to install Hotfix 2, the corresponding hardware update and a block setup. You will find more information at the following Internet page: http://www4.ad.siemens.de/WW/news/en/24463868

Programming − Using Blocks

For some communications services, there are pre-programmed blocks (FCs/FBs) available as the interface in your STEP 7 user program.

You will find a detailed description of these blocks in the NCM S7 for Ethernet manuals.

Notice

We recommend that you always use the latest block versions for all module types.

You will find information on the latest block version and links to download the current blocks in our Customer Support area on the Internet:

http://www4.ad.siemens.de/WW/news/en/8797900

If you are using older block types, this recommendation only applies if you also have the latest firmware version.

You will find further information and Internet addresses in the Preface of the General Part of this manual.

4 Displays

LEDs for displaying the CP communication status

In addition to the LEDs that signal the CP state, the following LEDs provide information about the status of the CP interface to Industrial Ethernet.

Table 4-1

LED			Display			Meaning
RX/TX (green)					The CP is sending/receiving over Industrial
					Ethernet
					Note:
					Sending / receiving over PROFINET IO is
					not signaled here.
P1 / P2					Port has no connection to
(green / yellow)					Industrial Ethernet.
				green	Existing connection over port to
					Industrial Ethernet (LINK status).
				green /	LED flashes yellow (constant light green):
				yellow	Port sending/receiving over
					Industrial Ethernet or PROFINET IO.
					Note:
					All received / sent frames are signaled for
					each specific port including those simply
					forwarded by the switch.
P1 / P2				yellow	Continuous data transfer at the port over
(green / yellow)					Industrial Ethernet (for example
					PROFINET IO).
