Process Visualization The range of SIMATIC HMI operating and monitoring products
includes three software families: SIMATIC WinCC (TIA Portal),
SIMATIC WinCC, and SIMATIC WinCC Open Architecture We
have already discussed one of these families, SIMATIC WinCC
(TIA Portal).
SIMATIC WinCC is a scalable, Windows-based process
visualization system, or what is sometimes called a supervisory
control and data acquisition (SCADA) system. SIMATIC WinCC
is scalable because it can be configured to provide complete
operating and monitoring functionality for simple, single-user
systems up to complex, multi-user systems with redundant
servers.
WinCC Open Architecture addresses solutions with highly
customer specific adaptation requirements and specialized
functions even on non-Windows platforms.
Process Control A variety of approaches can be used for process control
depending upon the complexity of the process being controlled.
A small batch process often lends itself well to control by one
PLC or a few networked PLCs.
Increasingly, variable frequency drives (VFDs) are also networked
to the PLC and HMI systems. These drives are used to control the
speed of pumps or fans that, in turn, control the flow of fluids
and gases. Flow control is frequently accomplished by using
control valves and vent damping systems to regulate flow while
running pump and fan motors at full voltage. Using variable
frequency drives for pump and fan control is a more energy
efficient approach to controlling process flow rates. Additional
efficiencies can be gained through use of more efficient motors
and by using smart MCC technologies, such as those available
with our tiastar MCCs, to integrate motor management and
process control.
