SCALANCE XCM-300 offers multiple interface configurations and performance parameters to meet the needs of different users. Specific models such as SCALANCE XCM324 and SCALANCE XCM328 have differences in the number of interfaces and performance. Here are some models as examples for explanation:
SCALANCE XCM324:
Interface configuration: 16 10/100/1000 Mbit/s RJ45 interfaces, 8 1/10 Gbit/s SFP+interfaces.
Performance: Supports Gigabit Ethernet and provides efficient data transmission capabilities.
SCALANCE XCM328:
Interface configuration: 24 10/100/1000 Mbit/s RJ45 interfaces, 4 1/10 Gbit/s SFP+interfaces.
Performance: It also supports Gigabit Ethernet and is suitable for applications that require more RJ45 interfaces.
Benefits
• Operalional relialbilly in industnial environments, e.g. due to robust enclosure, redundancy, extended temperalure range from -40 'C to +60 C
• Increased plant availability thanks to:
- Redundant power supply
- Redundant network structures based on a wide range of protocols
• Easy monitoring and diagnostics due to separate diagnoslics slalion withintegraed LEDs, siqnaing conlact, web browser, traps and emailtransmissionintegralion • into the SINEC NlS Network Management System for end-to-end network diagnostics with central firmware management
• Reduced engineering workload for PLC/HMl due to integralion into the SlMATlC system error message concept
• Time savings duing engineering, commisioning and in the operating phase of a plant by using the integrated configuration and diagnosics in TlA Portal
• Easy integration in process and system diagnostics with PROFINET or EtherNet/lP
• Integralion of $CALANCE XCM-300 switches in existing netvork management systems through SNMP access
• Reliable plug-in connection thanks to rugged,industry.-standard device conneclion in conjunction with industry-standard FastConnect connectors
• Low-maintenance operation thanks to fanless construction
Application
The main area of application is in high-performance plant networks (aggregation/control level) where a high number of ports and high transmission rates are necessary in addition to high requirements on the availability of the network and comprehensive diagnostics options.
The switch handles the Layer 2 networking of plant units as well as distributed field devices.
Other properties that support the application target include:
• One industrial network for data, voice, video and PROFINET
• Integrated system diagnostics possible with PROFINET, SINEC NMS, Syslog, SNMP and web browser
• Use in the SIMATIC environment
• Virtual networks (VLAN) allow simple division of large networks into smaller subnetworks with their own address space. Reasons for subdivision into subnetworks include separation of the Ethernet networks to reduce the broadcast load, separation of sensitive areas from the main network, and subdivision of the network into logical working groups.
• Integrated security functions offer protection against unauthorized network access and configuration; see technical specifications
• A flexible and easy way to analyze networks using the new Encapsulated Remote Traffic Mirroring (ERTM) function
Design
The SCALANCE XCM‑300 Industrial Ethernet switches with a rugged enclosure are optimized for mounting on DIN rails and SIMATIC S7-1500 DIN rails. Direct wall mounting in various positions and mounting on a SIMATIC S7-300 DIN rail are also possible. Due to the SIMATIC S7-1500 enclosure dimensions, the devices are optimally suited for integration into an automation solution with SIMATIC S7-1500 components.
The network access points in degree of protection IP20 have:
• A 2x 2-pin terminal block (push-in) for connecting the redundant supply voltage (2 x 24 V DC)
• The following status information is displayed on site by LEDs:
- Port status
- Port mode (e.g. 10/100/1000 Mbps, full/half-duplex)
- Status of the two power supplies
- Signaling contact status
- Signal mask (setpoint status)
• A 2-pin terminal block (push-in) for connecting the floating signaling contact
• A SELECT/SET button for on-site configuration of the signaling contact
The SCALANCE XCM-300 switches are available with the following port types:
10/100/1000 Mbps, RJ45 connection
• Automatic detection of data transmission rate (10, 100 or 1000 Mbps), with autosensing and autocrossover function for connecting IE FC cables via IE FC RJ45 plugs over distances up to 100 m.
1/2.5/5/10 Gbps, RJ45 connection
• Automatic detection of data transmission rate (1000, 2500, 5000 or 10000 Mbps), with autosensing and autocrossover function for connecting IE FC cables via IE FC RJ45 plugs over distances up to 100 m.
1/10 Gbps, SFP+ connector
• Use of 1000 Mbps or 10000 Mbps SFP+ transceiver for multimode or single-mode transceivers
The function extender interface (on the left side) is used to connect the SCALANCE LPE module. This allows applications to be integrated and used more conveniently on the network, e.g. applications that rely on mirrored network traffic.
Function
• Setup of electrical and optical Industrial Ethernet line, star and ring topologiesUse in ring topologies
- Use in ring topologies together with SCALANCE X-200, SCALANCE X-300, SCALANCE XM-400 and XR-500
• Uncrossed connecting cables can be used due to autocrossover function integrated in the ports
• Easy diagnostics using signaling contact, SNMP and web browser
• Easy copper cable diagnostics via web browser for localizing cable breaks
• Integration into the diagnostics of a PROFINET controller with expanded diagnostics functions for a consistent diagnostics concept, including network infrastructure
• Diagnostics of data traffic by means of a parameterizable mirror port with a standard commercial network analyzer
• Optimized support of PROFINET real-time communication (RT) through prioritizing
• Fast device replacement in the event of a fault by using the optional CLP removable data storage medium (included in scope of supply)
• Redundant connection to company networks
The SCALANCE XCM-300 switches support the standardized redundancy procedures Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP). This enables a subnetwork to be connected redundantly to a higher level corporate network with reduced requirements for the reconfiguration time (in the seconds range)
• Support of virtual LANs (VLANs)
For structuring Industrial Ethernet networks with a fast growing number of users, a physically existing network can be divided into several logical networks
• Load limiting with use of multicast protocols (e.g. querier, video)
By learning the multicast sources and targets (IGMP snooping), XCM-300 switches can also filter multicast data traffic, thus limiting the load in the network. Multicast and broadcast traffic can be limited.
