PROFINET Installation Tips & Tricks On Guidelines

PROFINET INSTALLATION TIPS AND TRICKS Are your PROFINET assets installed within specification? How do you ensure high network availability? Profinet is a very widely utilised Industrial Ethernet technology and is respected for its advanced diagnostics, simple commissioning, and robustness within various industrial environments. Within the installation and implementation of a Profinet network, various precautions should be taken, and standards put in place that should be adhered to. Without such adherence to the guidelines, communication issues may arise. Minimizing Interference and Noise Cable clearance guidelines Profinet cables running in close proximity to high voltage machinery and unshielded high voltage cables can cause severe EMC interference and disruption of the networks communications. Always maintain a minimum 20cm separation distance between Profinet cables and un-shielded supply cables (>400V) Fiber optics should be considered when running though an

Bridging SQL to Profibus

Introduction A client came to us with a situation where he required some data on his SQL database to be sent to his PLC. In his case, he has a couple of sensors inserting data directly to his SQL database and he needed these data to be processed by his Profibus PLC controller so that the correct actions could be taken. The solution accepted by the client was a SQL to Profibus bridge. IDX offered to provide a custom software that would extract the SQL data in real-time and expose the extracted data as a Modbus TCP slave device. The data could then be converted to a Profibus protocol using a gateway such as the Anybus X-Gateway AB9001, and sent directly to the PLC controller. IDX 8 We provided the client with a custom software called IDX 8. IDX 8 is a customised software offered by IDX, it contains a suite of different functionalities which includes tag management, remote monitoring, historian, alarms and events, data exchange, etc. The function of interest here is
