The data from the devices/controller need to be validated first in order to make it work. The validation can be part of the device driver itself (best choice) else can be performed by the layer above it. The validation will involve health check diagnostic to check whether the device is alive and communicating, feed back is readable (not any junk characters), etc.,
The validated device data has to be processed by any Logic building application. e.g. :
1. PI-Processbook from OSI soft http://www.osisoft.com/software-support/products/PI_ProcessBook.aspx
2. InTouch from Wonderware/ Invensys http://global.wonderware.com/EN/Pages/WonderwareInTouchHMI.aspx
3. Business Logic Editor in xMII module of SAP http://help.sap.com/saphelp_xmii115/helpdata/en/Introduction/IllumSystemOverview.htm
The above tools are provided user friendly logic building features. These tools are provided with industry standard data connectors or adapters. The following are the industry standard connectors
1. OPC (OLE for Process control) - Connecting to time series data from shop floor control system - http://www.opcfoundation.org/
2. OLEDB (Connect to different type of Relational Database Management System( RDBMS), ISAM (Indexed Sequential Access Method) for accessing flat files
