■
Overview
The module is used to connect a LOGO! and up to three other
nodes to an Industrial Ethernet network with 10/100 Mbit/s 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
■
Benefits
•
Reduction in assembly costs and mounting space compared
to use of external network components
•
Fast commissioning, as no configuration is necessary
•
Fast and uncomplicated diagnostics access in the control
cabinet
•
Flexible expansion of the network by simply inserting the CSM
■
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 program-
ming devices, other controllers, or the office world.
Problem-free external access (for diagnostics purposes, for ex-
ample) is possible via the four Ethernet ports.
Product versions
LOGO!CSM 12/24
•
For operation with DC power at a voltage of 12 and 24 volts
LOGO!CSM 230
•
For operation with alternating voltage of 110 and 230 volts
■
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
