Description 3.2 Network topologies Configuration example Sample configurations with SCALANCE X-400, SIMATIC S7-200/300/400, operator control and monitoring system, H system, and PC as end devices.
Description 3.2 Network topologies 3.2.4 Options of media redundancy There are various options available to increase the network availability of an Industrial Ethernet network with optical or electrical linear bus topologies: ● Mesh networks ● Parallel connection of transmission paths ● Closing a linear bus topology to form a ring topology 3.2.
Description 3.2 Network topologies How media redundancy works in a ring topology When using media redundancy, the data paths between the individual devices are reconfigured if the ring is interrupted at one point. Following reconfiguration of the topology, the devices can once again be reached in the resulting new topology. In the redundancy manager, the 2 ring ports are disconnected from each other if the network is uninterrupted. This prevents circulating data frames.
Description 3.2 Network topologies Requirements The following requirements must be met for problem-free operation with the MRP media redundancy protocol: ● MRP is supported in ring topologies with up to 50 devices. Exceeding this number of devices can lead to a loss of data traffic. ● The ring in which you want to use MRP may only consist of devices that support this function. This applies, for example, to the following devices: – Industrial Ethernet switches SCALANCE X-200 as of firmware version V4.
Description 3.2 Network topologies Topology The following schematic shows a possible topology for devices in a ring with MRP.
Description 3.2 Network topologies Requirements The following requirements must be met for problem-free operation with the HSR media redundancy method: ● HSR is supported in ring topologies with up to 50 devices. Exceeding this number of devices can lead to a loss of data traffic. ● The ring in which you want to use HSR may only consist of devices that support this function. This applies, for example, to the following devices: X-400 IE switches, X-300 IE switches, X-200 IE switches and OSM / ESM.

5 Connecting 5.1 Ports 5.1.1 Connectors of the power supply (X1) of the SCALANCE X-400 Polarity reversal protection X1, X2 The two 4-pin male connectors (X1, X2) for the power supply and the signaling contact have no polarity reversal protection. If the connectors are accidentally swapped over, this does not cause damage or destroy circuits. Normal functionality is, however, not available while the connectors are swapped over.
Connecting 5.1 Ports CAUTION If IE Switches X-400 are supplied over long 24 V power supply lines or networks, measures are necessary to prevent interference by strong electromagnetic pulses on the supply lines. These can result, for example, due to lightning or switching of large inductive loads. One of the tests used to attest the immunity of devices of the IE Switches X-400 to electromagnetic interference is the "surge immunity test" according to EN61000-4-5.
Connecting 5.1 Ports By inserting a strap between protective earth GND and M3, IE Switches X-400 can be operated with grounded reference potential. When the device ships, no strap is fitted (non-grounded reference potential). Conn. 2 5.1.

Glossary Aging time The aging time is the time after which a learned MAC address is discarded if a SCALANCE X-400 has not received frames with this sender address during this time. ARD Automatic Redundancy Detection. Autocrossover Technique with which a TP port is automatically switched over between MDI and MDIX assignment to make a connection independent of the port assignment of the device being attached. This means that crossover cables are not required.
Glossary Digital input A digital input is used to acquire binary file information. A state change can be logged in the Log Table or reported by E-mail or traps. The voltage levels between – 30 V and + 3 V correspond to logical state "0", voltage levels between + 13 V and + 30 V correspond to logical state "1". Dispersion Broadening and distortion of light pulses in fiber-optic cable due to signals arriving at different times.
Glossary HSR → High Speed Redundancy Latency Latency specifies the time taken by frames to pass through a switch. This does not include the time required for buffering frames. Load containment With its filtering functions, a switch makes sure that local data traffic remains local. The local network load of a segment is contained in the originating segment and does not represent extra load on the remainder of the network. MDI Medium Dependent Interface, - straight.
Glossary Mirroring A port (mirror port) with its specific data traffic can be mirrored to another port (monitor port) for test purposes. Protocol analysis devices can be connected to the monitor port, in other words, the monitor port is not available for data exchange. Mirroring has no effect on the mirror port. Modes Modes are discrete waves used to transmit data within a fiber-optic cable. With single mode fibers, only one wave propagates, whereas in multimode fibers several waves propagate.
Glossary Redundancy domain Group of devices that support the "media redundancy" function in a ring topology. All devices in a ring topology with media redundancy must belong to the same redundancy domain. Redundancy manager Device in a ring network section with ►media redundancy that monitors the ring topology. Only one of the two ►ring ports of the redundancy manager forwards data frames when the ring is closed.
Glossary the wavelength of the input light. The single mode fiber typically has a core diameter of 5 to 9 µm. The outer diameter is, however, once again 125 µm (compare multimode). The smaller core diameter degrades the pulse edges less than multimode transmission and allows greater transmission distances. SNMP Simple Network Management Protocol. Standardized protocol for transporting network management information. Spanning Tree The Spanning Tree protocol (STP) allows redundant transmission paths.
