Diagnostics
During the operations different events may occur. Prode Interface includes procedures for validating data and generating error / warning messages when the program detects a possible problem. When the problem is related to one (or more) ports the program can use different colors to emphasize the row (in the list of ports) which is related with the detected problem.

Technical features overview
Fully customizable list for inputs (specifications) and outputs (properties to be calculated) more than 30 thermodynamic properties available (many additional properties on request) Support for up to 20 different streams (up to 100 components per stream), each stream supports a different list of components, thermodynamic models etc.
Capability to relay each input to OPC and MODBUS ports
Customizable parameters for OPC and MODBUS ports
Automatic diagnostic and error reporting
