Results: • High Voltage: • The good news is that the delivered voltages remain unaffected by any communication failures, power cuts etc.. • The software controlled settings correspond to the true physical values (no local display available on crate or module) • Low Voltage: • PS behavior with SLIC.OPC (custom solution) regarding local setting ok • Main constrains : • Company (Wiener) OPC server not available yet • Control of single channels (On/OFF, Error Clearing, Reset…) for the PL500 not possible LECC 2003, Amsterdam, S.Popescu
