Compact Switch Module Siemens CSM 1277 – 6GK7277-1AA10-0AA0

Overview

  • Unmanaged switch for connecting a SIMATIC S7-1200 to an Industrial Ethernet network with a line, tree or star topology
  • Multiplication of Ethernet interfaces on a SIMATIC S7-1200 for additional connection of up to three programming devices, operator controls, and further Ethernet nodes
  • Simple, space-saving mounting on the SIMATIC S7-1200 DIN rail
  • Low-cost solution for implementing small, local Ethernet networks
  • Connection without any problems using RJ45 standard plug connectors
  • Simple and fast status display via LEDs on the device
  • Integral autocrossover function permits use of uncrossed connecting cables

Benefits

  • Savings on installation costs and space compared to using an external network component
  • Fast commissioning, as no configuration is necessary
  • Flexible expansion of the network by simply inserting the CSM

Application

The CSM 1277 is an Industrial Ethernet switch of compact design for use in the SIMATIC S7-1200. The CSM 1277 can be used to multiply the Ethernet interface of the SIMATIC S7-1200 for simultaneous communication with operator panels, programming devices, other controllers, or the office world.

The CSM 1277 and the SIMATIC S7-1200 controller can be used to implement simple automation networks at low cost.

Design

The CSM 1277 compact switch module offers all advantages of the SIMATIC S7-1200 design:

  • Compact design;
    the rugged plastic enclosure contains:

    • 4 x RJ45 ports for connecting to Industrial Ethernet
    • 3-pole plug-in terminal strip for connection of the external 24 V DC supply on the top
    • LEDs for diagnostics and for status display of the Industrial Ethernet ports
  • Simple mounting on the mounting rail of the S7-1200
  • Fanless and consequently low-maintenance design
  • The module can be replaced without using a programming device

Function

  • Multiplication of Ethernet interfaces of the SIMATIC S7-1200
  • 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 using the CSM 1277 compact switch module:

  • Connection of SIMATIC S7-1200 in linear topology:
    at least one RJ45 connection of the SIMATIC S7-1200 remains vacant, e.g. for connecting a programming device (PG)
  • Connection of SIMATIC S7-1200 to a higher-level network in a tree/star topology:
    at least two RJ45 connections of the SIMATIC S7-1200 remain vacant, e.g. for connecting a programming device/operator panel (PG/OP)
  • Design of a small, local network with a SIMATIC S7-1200 and three further Ethernet nodes

Configuration

The CSM 1277 compact switch module is an unmanaged switch and need not be configured.

Diagnostics
