Description

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.

• 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 autocross over function permits use of uncrossed connecting cables
• 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

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 autocross over 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

The following information is displayed on LEDs on the device:

• Power
• Port status
• Data traffic
