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.
