19 / 28 page ![]() IB IL SGI 2/P-PAC 7647_en_04 PHOENIX CONTACT 19 Parameters for configuration The values displayed in bold are pre-settings. Bits 10 to 9: Bit 4: Bit 3 to bit 0: Step response and limit frequencies The following table specifies the time for the step response and the limit frequency depending on the settings for conver- sion time and mean-value. 18 Process data input words IN 18.1 Input word IN0 (status word) Input word IN0 performs the task of a status word. EB: Error Bit The error bit indicates whether a command could be executed without errors or not. For the command code 4000hex (configure device), a set error bit indicates an invalid configuration. Possible reasons: – At least one of reserved bits is set. – An invalid value was specified for the nominal character- istic value. For the command code 0000 hex (read measured values), the error bit indicates a group error message. When the error bit is set, there is an error message on one or both channels. Mirrored command code: A command code mirrored from the control word. Here, the MSB is suppressed.
