The switching technology of the Industrial Ethernet OSM Version 2/ESM (Optical/Electrical Switching Module) allows the structuring of Ethernet networks with large spans and large numbers of nodes. It simplifies network configuration and network expansions. The OSM Version 2/ESM are simply called OSM/ESM in the rest of this manual.

The OSMs have both electrical ports and additional FO ports via which several of these devices can be interconnected to form an optical bus or ring configuration. ESMs only have electrical ports.

DTEs, other OSMs/ESMs or complete network segments operating at 10 or 100 Mbps can be connected to the electrical autonegotiation (autosensing) ports of the OSM/ESM. The transmission rate is detected automatically.

To increase availability, ring configurations can be created with OSMs or ESMs. To do this, OSMs or ESMs are first connected together to form a bus using their ring ports. The ends of the bus are closed to form a ring by an OSM or ESM operating in the Redundancy Manager mode (RM mode).

The OSM or ESM operating in the RM mode monitors the attached bus and allows a connection through it if it detects an interruption on the attached bus; in other words, it reestablishes a function bus. Reconfiguration is completed within 0.3s. An OSM/ESM is switched over to the RM mode using a DIP switch on the device.

The redundant standby coupling allows the redundant coupling of OSM/ESM or OLM rings. To do this, two OSM/ESMs (one operating in standby mode) are connected via their standby-sync ports.

With the ITP variants of the OSM/ESM, the DTEs are connected using sub-D female connectors. This connector technology allows direct links over distances up to 100 m. With the TP variants, the DTEs are connected using RJ-45 jacks.

The Version 2 OSMs are compatible with the previous OSM variants (6GK 1105- 0AA00) and ORM (6GK1105-1AA00) and can, for example, be mixed with these in an optical ring.

This manual describes the functions of the OSM/ESM available without using network management. The OSM/ESM Network Management user manual /1/ describes the additional options available if you use network management. You will find this manual on the CD accompanying every OSM/ESM or you can download the manual from the Web in Siemens Customer Support under entry number 8677203:
