New Modules Connect Optical and Electrical PROFIBUS Networks

Siemens Industry has released two new optical link modules specifically designed for PROFIBUS networks. The new modules, the OLM P22 which is designed for use with plastic fiber optic cables (FOC) and the OLM G22 which is compatible with glass FOCs, make it possible for users to employ more redundant and reliable network topologies, such as rings and stars, that ensure higher network availability, says Paul Ruland, Siemens marketing manager. “They also offer enhanced diagnostics... Read More

Transitioning from Fieldbus to Ethernet: Benefits and Requirements for the Plant Floor

Ethernet long ago became the de facto network standard for enterprise office networks on the strength of its performance, wide availability, openness and cost-effectiveness. For many of the same reasons, Ethernet has been finding its way to factory floor networks, a fact that may give pause to plant engineers who have long relied on fieldbus technology to foster communications among their various machines and devices. While any kind of change can be cause for concern, the transition... Read More

Finding Harmony on the Factory Floor

PROFINET, PROFIBUS team up to link entire enterprise. Over the past several years, Ethernet has made an impressive footprint on the plant floor, becoming the de facto standard for most new installations and expansions. But fieldbuses like PROFIBUS show no signs of fading away soon, making it important to understand how they work together.CLICK TO ENLARGEEthernet has been beefed up by many companies and trade groups so it can work in harsh industrial environments without sacrificing... Read More
