SimApi

About SimApis

A SimApi is a software interface between the Umetrics Suite software and a data source. The primary purpose of a SimApi is to provide data to SIMCA®-online or SIMCA®.

Sartorius Stedim Data Analytics develops SimApis for many different data sources, such as process historians and general purpose databases. There are also SimApis offered by partners and other companies.

Optimize Your Manufacturing Processes with Actionable Insights

The Sartorius Stedim Data Analytics MFCS 4 SimApi allows Umetrics® Suite of software solutions to access BioPAT® MFCS software and obtain historical and on-line process data from the connected bioreactors.

The Sartorius Stedim Data Analytics DA SimApi connects to a data source using the industry standard OPC DA.

The Sartorius Data Analytics HDA SimApi connects to a data source using the industry standard OPC HDA.

The OPC UA SimApi connects to an OPC UA (Unified Architecture) server.

The Sartorius Data Analytics ODBC SimApi connects to a SQL database with process data. The required database schema is described in the user guide.

The OSIsoft PI interface connects to to an OSIsoft PI Server, specifically the PI Data Archive. The interface can connect to both the PI Batch Database and the PI Asset Framework (AF). Read more at the OSIsoft Partner Solutions Showcase.

This interface is offered by OSIsoft who in their terminology refers to it as the PI interface for SIMCA®-online or SimBatchOL, with part number PI-IN-SIM-BO-NT.

Download documentation and view the latest technical news at OSIsoft (registration required). The installation kits for the interface must be obtained by contacting OSIsoft.

2017-09-30: OSIsoft will continue supporting this interface but will stop selling it. Customers should instead use the Sartorius Stedim Data Analytics PI AF SimApi (see above)

The Sartorius Stedim Data Analytics PI AF SimApi connects to an OSIsoft PI Server, specifically the PI Data Archive and the PI AF (Asset Framework) Server.

This SimApi is built by and fully supported by Sartorius Stedim Data Analytics unlike the OSIsoft PI SimApi described in the next section.

The Siemens SIPAT SimApi connects to a Siemens SIPAT data source.
This SimApi is provided by Siemens, please contact Siemens for further details.

The Sartorius Stedim Data Analytics Wonderware Historian SimApi connects to a Wonderware Historian data source. 

Feature matrix

Not all data sources are alike. A SimApi need not implement all functions in the specification. For these reasons, different SimApis offer different functionality. The following matrix lists available SimApis and their features.


Feature  

Purpose

SIMCA®-online usage

SIMCA® usage

Current data

Read a single observation with the most recent value from the data source

Real-time normal execution

 

Historical data

Read many observations at once with historical data from the data source

Catch-up and predict of past data, create projects using File > New

Database Import Wizard to import process data for model creation.

Discrete data

Read laboratory/IPC data from the data source. Many observations per batch.

For batch projects with phases or batch conditions configured for discrete data retrieval

 

Batch data

Read batch conditions and final quality attributes (or other MES type data). One observation per batch.

Batch conditions or local centering.

Database Import Wizard to read batch conditions for batch level model creation.

Batch node

Specify the start time and the end time (empty for an active batch) for a specific batch. Enumerate all batches that existed in a time range.

Required for execution of batch configurations.

Database Import Wizard to select batches to import.

Write back - continuous data

Write continuous data, such as predictions, back to the data source.

Write back data from the batch evolution level, for Control Advisor or for continuous configurations

 

Write back - discrete

Write discrete data, such as predictions, back to the data source.

Write back for batch configurations at the batch evolution level for phases configured for discrete data retrieval

 

Write back - batch data

Write back batch level data, such as predictions or final quality attributes, to the data source.

Write back for batch configuration at the batch level

 

Node hierarchy

The SimApi supports a hierarchy of nodes, similarly to a file system. Each node can contain tags and other nodes. The hierarchy makes is easier to manage a large number of nodes and tags.

Supported in all places where tags are used.

 

Array tag expansion

An array tag stores multiple values. The SimApi expands the array tag to many individual tags, one for each element in the array.

Supported where tags are used for continuous data. Each expanded tag must be mapped to a variable in the SIMCA project.

 

Multiple data sources

The SimApi can connect to more than a single data source or supports multiple instances of itself with individual settings and log files for each instance.

Connect to several different data sources of the same kind. 

 

Connection resiliency

If the SimApi becomes disconnected from the data source, it will try to reestablish the connection automatically.

The SimApi doesn’t have to be restarted to reestablish connections to the data source.

 

Thread-safe concurrent access

The SimApi can safely handle more than one thread accessing it concurrently which can improve performance.

When Concurrent SimApiaccess has been enabled on the SIMCA-online 18 server, data access can be performed by more than one thread in parallel which can improve performance and responsiveness.

 

Developed in-house

The SimApi is developed, provided and supported by Sartorius Stedim Data Analytics AB.


SIMCA® can use a SimApi to retrieve data for project creation and model building as the following picture illustrates. 

SIMCA®-online uses SimApis to obtain data in real-time for monitoring and control, as well as write-back of data to the data source. The following picture shows where the SimApi is located in a system consisting of a data source, SIMCA®-online server, and clients
