Controling application of the test course of flowmeters. Controlling the technology, managing the measurement device catalogue in SQL database, computing the measured values, archiving the data into SQL, procesing the measurement protocols. Communication with the devices via the serial link.:
The communication between the PC and PLC is done via the Ethernet TCP/IP protocol by Softing OPC server.
Collecting the measured data from the PLC device, periferies (weight scales connected via the computer's serial port, communication by PmChar
Processing, computing errors, volumes, test times and other data needed to complete the measurement protocol of the corresponding device.
Choosing the parameters of specific test, selecting the measurement device type from own created SQL database (managed by this application).
The collected data is stored in a SQL database, prepared for search, filtering (for specific measurement device type) and print of current and archived protocols.
The measured data is used to create a protocol (PDF file) that is stored in a separate independent protocol database, that can also be searched (by SQL queries) for further usage.
After the specific measurement procedure protocol is found the corresponding portion of the chart (trend) is displayed.
There are multiple configuration text files used for user configurations.
