PID Professional (TIA Portal)

Commissioning software

The configuration tool is seamlessly integrated into STEP 7 (TIA Portal). It provides the following functions:

Commissioning screens:
The commissioning software contains all screens for commissioning Modular and Standard PID Control.
Working with trend view:
The trend view is used for graphical illustration of the setpoint, actual value and manipulated variable over time. The values of the trend view are updated at configurable intervals. This is of particular benefit for the verification of the process quality and supports the troubleshooting.
Wizard for optimization of control circuits:
The clear and simple controller optimization and the commissioning by means of the PID Self-Tuner can be performed even without any knowledge of control systems.
Variable transient response in the case of the continuous PID controller:
The transient response of the control loop can be preselected in such a way that the control loop settles with an overshoot of approximately 10% and therefore gains dynamic response. If this is not desirable, aperiodic settling (no overshoot) can be set.
User-friendly, context-sensitive help:
At any point in the program the appropriate help is available upon request.

Standard PID Control functions

The controller structure for Standard PID Control is pre-assembled and the data structure is fixed. The following functions can be switched on and off by means of software switches:

Setpoint processing with setpoint value generator, ramp-soak, normalization, FC call, limiting of the setpoint ramp (ramp-function generator) and limiting of the setpoint.
Actual-value processing with scaling, smoothing, square root, FC call, limit value monitoring and monitoring of the actual-value gradient.
Error signal processing with dead band and limit monitoring.
PID algorithm, in the case of step controllers with and without position feedback.
Manipulated value processing, with manual/automatic switchover, manual value generator, FC call, limiting of the setpoint gradient, setpoint limitation and normalization

Standard function blocks

FB/FC	Functions
PID_CP	PID controller with continuous manipulated variable (continuous controller) or pulse output (pulse controller); in addition to the functions in the setpoint and actual-value branch, it implements a complete PID controller with a continuous manipulated variable, which is also made available as a pulse-width-modulated signal; manipulated variable can also be influenced manually, sub-functions can be connected or disconnected
PID_ES	PID controller with binary manipulated variable (step controller); in addition to the functions in the setpoint and actual-value branch, it implements a complete PID controller with a binary manipulated variable for integrating actuators. The step controller can be implemented with or without position feedback; manipulated variable can also be influenced manually, sub-functions can be connected or disconnected
LP_SCHED	Loop scheduler; controls the calling of individual control loops within the cyclic interrupt level

Modular PID Control functions

The controller structure of Modular PID Control is, on the other hand, fully programmable. The following functions are available:

Standard function blocks

FB/FC	Comment	Functions
A_DEAD_B	Adaptive dead band	Filters higher-frequency interfering signals out of the error signal
CRP_IN	Convert analog input value	Input values in I/O format are converted to floating-point values for Modular PID Control
CPR_OUT	Convert analog output value	A floating-point value from Modular PID Control is converted into an output value in I/O format
DEAD_T	Dead time	Delays an input value by a configurable dead time
DEADBAND	Dead band	Differentiates the input variable as a function of the time and smoothes the signal with a first-order delay element
DIF	Derivative-action element	Calculates the error signal and monitors it for limits that can be entered
ERR_MON	Error signal monitoring	Calculates the error signal and monitors it for limits that can be entered
INTEG	Integrator	Integrates an input variable as a function of the time and limits the output to the definable limits
LAG1ST	First-order delay element	Implements a first-order delay element
LAG2ND	Second-order delay element	Implements a second-order delay element
LIMALARM	Limit monitor	Checks an input value for 4 configurable limits
LIMITER	Limitation	Sets configurable limits for an input variable
LMNGEN_C	Output of continuous-action PID controller	Contains the manipulated variable processing unit for a continuous-action PID controller. It always has to be used in combination with the PID algorithm block.
LMNGEN_S	Output of PID step controller	Contains the manipulated variable processing unit for a step controller for integrating actuators. It is always interconnected with the PID algorithm block.
LP_SCHED	Controller call distribution function	Controls the calling of individual control loops within a cyclic interrupt level
NONLIN	Non-linear static characteristic	Forms a non-linear characteristic (polyline)
NORM	Physical normalization	Scales an input variable. The normalization line is defined by 2 points.
OVERRIDE	Override control	Required for implementing an override control
PARA_CTL	Parameter control	Transfers several controller parameter sets to a PID controller
PID	PID algorithm	Provides a PID algorithm and must always be used in conjunction with LMNGEN_C or LMNGEN_S
PULSEGEN	Pulse shaper	Generates the pulse output for PID controllers with pulse output for proportional actuators
RMP_SOAK	Ramp soak	Performs configured/programmed ramp soak curves
ROC_LIM	Ramp or ramp-function generator	Limits the rate of change of an input variable. Step jump functions become ramp functions.
SCALE	Linear scaling	Scales an input variable. The normalization line is defined by factor and offset.
SP_GEN	Setpoint generator	Changes the output value continuously by means of pushbuttons
SPLT_RAN	Split ranging	Required for implementing a split-range control
SWITCH	Analog value switch	Switches one of 2 input values to one of 2 output values
