Sequence Table

The CIP operation can also be displayed in a Sequence Table showing the progression of the CIP stages, identifying which ‘events’ occurred together, how long each ‘step’ took and what time had elapsed since the start of the CIP operation.

The sequence table also shows the value of analogue signals relevant at each step and the CIP cycle, (pre-rinse, etc.) that was being executed at each of the programme steps.

Each digital signal (event) can be independently switched on/off to minimise information displayed. The analogue signals shown can be inter-changed in the sequence table to aid in the analysis of data.

The analogue signals displayed (to the right of the Sequence Table) can be changed to show alternative signal values by simply clicking on Analogue Signal Select button at the bottom of the report.  This brings up a menu permitting the required signals to be selected.

The number of analogue signals shown at any one time is limited to 3. Displaying all 8 or 10 signals simultaneously would overwhelm the report/display screen with too much data, the digital signals would have to be condensed to make room for all the data to be display at once.

Although analogue signals can be changed, all other information remains unaltered. This enables the data analyst to focus on specific detail regarding the analogue values without loosing general information on the individual programme steps or stages.
