Bit 7: Span Status Indicates whether the unit is currently performing a Span calibration. Application Layer Bits 8 to 11: Totalizer Status Indicate “1” if the reset totalizer or print operations are taking place (these are momentary and will only stay set for a very short period). (Note: Bit 10 applies only to BW500 and SF500.) Bit 12: Write Privileges Indicates whether the PLC can write parameters/commands to the product. This is controlled by parameter P799. P799 = 1 PLC may change the Siemens Milltronics SmartLinx instrument’s parameters P799 = 0 PLC can only read Bit 13: Configuration Status Indicates whether the unit is configured (all required parameters have been entered). Bit 14:
Program Mode Indicates program (calibration) mode: 0 = PROGRAM mode 1 = RUN mode Bit 15: Totalizing Status Indicates whether the unit is totalizing. Rate Contains the current rate reading in engineering units (For a full description of this reading, please refer to your Milltronics Integrator manual). Load Contains the current load reading in engineering units (For a full description of this reading, please refer to your Milltronics Integrator manual). Speed Contains the current speed reading in engineering units (For a full description of this reading, please refer to your Milltronics Integrator manual).
Total 1 1 Contains the current value for totalizer 1 in engineering units (For a full description of this reading, please refer to your Milltronics Integrator manual). 1. The number of fixed decimal places for this value is controlled by P634 primary indexes 1 and 2. The default setting is 3; see page 18 for details. 7ML19981AQ03 SmartLinx PROFIBUS DP – INSTRUCTION MANUAL Page 37
