The LDSCycleParametersEventType represents information on a dosing cycle. A complete dosing is defined from the beginning of the dosing signal to the next one, i.e. the event for cycle n is fired, when the dosing signal for cycle n+1 starts.

Number of the dosing cycle. Gets counted up after each dosing cycle.

Example: 900

Duration of the dosing cycle.

Target mixing ratio of the last cycle (includes ratio change when MaterialBalanceSystem is active). The share of component A (in percent) defines the value:

Examples:50 (A 50 : 50 B) without MaterialBalanceSystem

51,25 (A 51,25 : 48,75 B) active MaterialBalanceSystem

Actual mixing ratio of the components. The share of component A defines the value:

Example: 50,9(A 50,9 : 49,1 B)

Target ratios of additives in percentage which are set in AdditiveFraction of AdditiveType.

Actual ratios of additive in percentage.

Example: [ 2,1 % ; 1,2 % ]

Volume of component A that was added to the process in the last cycle.

Unit: cm³ or in³

Volume of component B that was added to the process in the last cycle.

Unit: cm³ or in³

Volume of components A + B that was added to the process in the last cycle.

Unit: cm³ or in³

Volumes of the additives that were added to the process in the last cycle

Unit: cm³ or in³

Volume of all components (A + B + all additives)

Unit: cm³ or in³

Residual weight amount of component A at the end of the dosing cycle.

Unit: kg or lb

Residual weight amount of component B at the end of the dosing cycle.

Unit: kg or lb

Average pressure of component A during the last cycle at the blender.

Unit: bar or psi

Average pressure of component B during the last cycle at the blender.

Unit: bar or psi

Average pressure of components A&B during the last cycle at the blender.

Unit: bar or psi

Average pressure of the additive during the last cycle at the measuring point.

Unit: bar or psi

Average material pressure during the last cycle before and after the filter. The Pressure difference between FilterPressurePrimary & FilterPressureSecondary can be used to check if the filter is blocked/ will be blocked soon/ has to be maintained. Unit: bar or psi
