Erhardt+Leimer devices receive ODVA certification
The Ethernet/IP interfaces for the web tension measuring amplifier PA 62 and the control card RK 4030 from Erhardt+Leimer Group (Stadtbergen, Germany) have recently received ODVA certification.
The control card RK 4030 is integrated into most web guiding systems from E+L. This interface makes it possible to set web offset values, choose sensors and select and control operation modes. Information about the selected sensor and active operation mode can also be accessed.
The interface for the web tension measuring amplifier PA 62 supports the setting of min./max. values and the accessing of all current (threshold) values and warnings.
All supported functions are now CIPTM (Common Industrial Protocol) certified and fulfil the latest interface specification standard. These functions include the IP configuration, specifying whether the IP address is to be set via DHCP or a static preset address is to be used, QoS (Quality of Service) settings, which transmit the message prioritisation, the Ethernet link setting and the recognition of address conflicts (duplicate IP addresses).
This certification is a milestone for Erhardt+Leimer at the end of a lengthy and involved process. The final test by the IAF (Institute of Ergonomics, Manufacturing Systems and Automation) at the University of Magdeburg was passed with flying colours at first go by both E+L devices.The next challenge ahead is the certification for Profinet by the PNO (German PROFIBUS regional association).
