Description

The module is used to connect a LOGO! and up to three other nodes to an Industrial Ethernet network with 10/100 Mbps in an electrical linear, tree or star topology.

The essential features of the LOGO! CSM are:

• Unmanaged 4-port switch, of which one port is on the front for easy diagnostics access
• Two versions for the voltage ranges 12/24 V DC or 230 V AC/DC
• Problem-free connection using four RJ45 standard connectors
• Space-saving, optimized for connection to LOGO!
• Low-cost solution for implementing small, local Ethernet networks
• Stand-alone use for networking any Ethernet devices

Application

The LOGO! CSM is an Industrial Ethernet switch in compact, modular design for use in devices of the new LOGO! generation with Industrial Ethernet connection. With the LOGO! CSM, the Ethernet interface of the SIMATIC LOGO! can be multiplied to enable simultaneous communication with control and programming devices, other controllers, or the office world.

Problem-free external access (for diagnostics purposes, for example) is possible via the four Ethernet ports.

Design

The design of the LOGO! CSM Compact Switch Modules corresponds to that of the LOGO! components:

• Compact design;
• the rugged plastic enclosure contains:
• 4 x RJ45 ports for connecting to Industrial Ethernet; of which one port is on the front for easy diagnostics access
• 3-pin connection for the external supply voltage
• LEDs for diagnostics and for status display of the Industrial Ethernet ports
• Simple mounting on the standard mounting rail
• Fanless and consequently low-maintenance design

Function

• Multiplication of the Ethernet interfaces for logic modules of the product range LOGO! with Ethernet connection (…-0BA7 and -0BA8)
• Design of a small, local Industrial Ethernet network with three further nodes
• Automatic detection of data transfer rate by means of autosensing and autocrossover functions
• LEDs for diagnostics and for status display

Network topology and network configuration

Various network topologies can be implemented with LOGO! CSM:

• Connection of the LOGO! in linear topology: at least one RJ45 connection of the LOGO! remains vacant, e.g. for connecting a programming device (PG)
• Connection of the LOGO! to a higher-level network in a tree/star topology: at least two RJ45 connections of the LOGO! remain vacant, e.g. for connecting a programming device/operator panel (PG/OP)
• Design of a small, local network with a LOGO! and three further Ethernet nodes

Configuration

LOGO! CSM is an unmanaged switch and does not require configuration.

Diagnostics
