Programming: Create process calculations that use OPC tags


East Rochester, NY —Exele Information Systems Inc. announces OPCcalc 3.2, software that lets users create process calculations that use OPC tags as equation inputs and outputs. The software handles simple to complex equations, single to multiple OPC servers, and single-computer or enterprise-wide applications. Described as a vendor-neutral, process calculation framework for OPC data. OPCcalc allows those with process knowledge to quickly create robust calculations.


OPCcalc 3.2 adds new features and performance enhancements, including:


  • Additional diagnostics that allow users to monitor the health of running equations. New diagnostics include equation execution times, last completed execution, and missed executions;

  • Improved performance and host machine configuration that allow users to run more equations on a single machine than previously possible; and

  • Bulk equation building that lets users rebuild a collection of equations in one step.


The software requires Microsoft Windows 2000 or later, a Visual Basic.Net 2005 compiler (VB Express 2005 free edition supported), and OPC DA Server (supporting Data Access version 2 or later). OPC HDA Server is optional (supporting Historical Data Access version 1.1)
