Compact Switch Module - Siemens SIMATIC NET System Manual

Compact switch module

Overview
The Compact Switch Modules are industrial Ethernet switches with a compact, modular
design for use in the immediate vicinity of the SIMATIC S7 CPUs. Using a CSM, the
Ethernet interface of a SIMATIC S7 CPU can be multiplied. This means that simultaneous
communication with operator control and programming devices, other controllers or office
networks is possible.
With a CSM and the SIMATIC S7 controller, simple, low-cost automation networks can be
implemented.
Device versions
Currently, there are four device types of the Compact Switch Module available. These differ
in terms of their construction and the installation options:
● The CSM 377 unmanaged meets the requirements of rugged SIMATIC S7-300
technology and is installed on an S7-300 standard rail. The module is designed according
to the standards EN 61000-6-2:2001 and EN 61000-6-4:2001.
● The CSM 1277 unmanaged corresponds to the industrial, technical requirements of the
new SIMATIC generation S7-1200. It is intended for installation on a S7-1200 standard
rail. The module conforms with the standards EN 61000-6-2 and EN 61000-6-4.
● The SIPLUS NET CSM 1277 is an unmanaged switch for unusual environmental
conditions. The module is in conformity with the standards EN 60721-3-3 of the class
3B2, EN 60721-3-3 of the class 3C4 incl. salt spray as well as the ISA –S71.04, the
immunity test levels G1, G2, G3 and GX.
● LOGO! CSM is designed with four RJ45 ports for external access or connection to
Industrial Ethernet networks. With the LOGO! CMS an Ethernet interface of the SIMATIC
LOGO! system modules can be multiplied. This means that simultaneous communication
with operator control and programming devices, other controllers or office environments
is possible.
It is installed on a standard rail.
Two product variants are available:
– LOGO! CSM 12/24 for operation with direct current at a voltage of 12 V and 24 V
– LOGO! CSM 230 for the operation with an AC voltage of 110 V and 230 V
