SIMATIC IT for OEESIMATIC IT for OEE

SIMATIC IT OEE-DTM is a product option of SIMATIC IT Historian, and it is wholly and seamlessly integrated within the entire MES solution

SIMATIC IT for OEE, through integration with the entire SIMATIC IT environment, allows:

• the calculation of all “standard” and “custom” KPIs

• to fully support the Downtime Management

• to perform active and corrective actions to react to efficiency decreases

• to improve economic Return on Investments (ROI)

• to maximize the plant performance

Pre-defined standard KPIs algorithms:Availability rate, Performance rate, Quality rate, OEE, MTTA, MTBF, MTTR, MTBA, and more…

Possibility to create new custom KPIs algorithms,combining the existing ones or implementing brand new ones

All th i di t d b SIMATIC IT OEE DTM il bl ithAll these indicators, managed by SIMATIC IT OEE-DTM, are available either :

Planned / Induced DowntimePlanned / Induced Downtime

Two special types of downtime records defined either through a dedicated OEETwo special types of downtime records, defined either through a dedicated OEE Web Client page, or programmatically through COM or GSI methods:

Pl d D tiPlanned Downtimes• which cause OEE to disregard the status information retrieved from the field

for the specified time span, are used when an equipment have predefined planned time where it is off-line.

Induced Downtimes• used to model a ”bottleneck“ situation, where the machine state of a piece of

equipment depends on the state of another piece of equipment. They are q p p p q p yused to put in Downtime status an equipment on real-time.



Planned DowntimePlanned Downtime

A Pl d D ti i i d f d ti fi d t i th f tA Planned Downtime is a period of downtime configured to occur in the future.

Th f ll i t d fi l d d tiThe following parameters define a planned downtime:

• A start-time and an end-time (b th i th f t )(both in the future)

• A machine state

• The piece(s) of equipment involved



Induced DowntimeInduced Downtime
