Basic Processing.

Network Control

Message processing

• Processing of status information, also with time-stamping
• Evaluation of acquisition states

Measured-value processing

• Conversion of raw data
• Checking plausibility of measured values
• Adaptation to transmitter characteristics via linear or polygonal scaling
• Checking for limit-value violations and unacceptable change rates
• Automatic generation of replacement values
• Evaluation of acquisition status

Count-value processing

• Conversion of raw values
• Cyclic processing as absolute or differential value
• Comparison of maximum and minimum number of pulses per cycle

Event processing

• Constant or variable limit values (hysteresis possible)
• Summing of the ON/OFF cycles and the duration of all equipment ON states for monitoring purposes
• Saving of all events in cyclic buffers, the size of which can be configured
• Processing of alarms and alarm lists
• Provision of the data requested by the MMI
• Transfer of data to external programs (e.g. mimic panel control)

Command processing

• Consideration of an enable condition for each command
• Parameterization of command monitoring time
• Output of setpoints with scaling
• Commands are not output when processing has been disabled, or if there is a remote fault, or if local/remote switch has been set accordingly.

Link processing

• Processing link lists
• Consideration of enable PVs
• Logic functions
• Arithmetic operations, e.g. exponent, logarithm, trigonometric and hyperbolic functions

Replacement value processing

• Provision of replacement values for PVs which are at fault or have been disabled by the operator
• Replacement values can be constants or the contents of other PVs

Key switch processing

• With the help of key switches, privilege levels can be defined for the various areas of operation (e.g. control, system changes).

Archive processing

• Archiving of values with status and time
• Archive periods, time-grid cycles, compression levels can be parametrized
• Archiving times (high-tariff/lowtariff) can be controlled
• Mean, minimum or maximum values and summation algorithms for grid archives
• Grid archives with time grid, e.g. in minute/hour/day/month cycles
• Dynamic archives for rare events or for temporarily high data rates
• Correction possibility with labeling
• Automatic post-compression in the compression levels after manual correction
• Protection functions: online reorganization, long-term archiving on removable data media

System message processing

• Communication faults between process interface and sub-stations
•Failure of a telecontrol line
•Failure of a workstation computer
