Engineering tool operation II-4.6 9499-040-82711 Trend function Survey of the characteristics Apart from the trend function specially designed for “Controllers” (CONTR, CONTR+) of the simulation package SIM/KS 98-1, additional trend windows can be implemented. Each trend is able to display 7 analog values and 12 logic states from the Engineering against a time axis. Several independent trend displays can be shown simultaneously.
9499-040-82711 Engineering tool operation Preparations in the ET/KS 98 The trend function is an application that runs independently of the Engineering Tool. The values to be displayed are re ceived directly from the KS 98-1 or from the simulation software SIM/KS 98-1. Data trans-mission is executed via the communication modules L1READ (blocks 1...20), which must first be configured. For each L1READ, 7 analog values and 12 logic statuses from the Engineering can be “connected”.
Engineering tool operation 9499-040-82711 Fig.: 96 Trend dialog box (trend display not yet started) Trend recording of the selected L1READ function can now be started directly with the “Start” button. The trend para meters can be changed previously by means of the “Change” button. The duration of the trend curve (visible time axis) is determined by the product of “Sampling time x sampling steps”.

Building an engineering 9499-040-82711 For controlling, we also need a controller (in Functions - Controllers > CONTR). # < This controller should be positioned behind the input. The same we do with the OUT4 and place him below the controller. In the next step, we have to soft-wire the function blocks, in order to provide a connection from the input via the con troller to the output. > For this purpose, we can select the wiring mode (via menu Edit – Wiring or by a simple double-click).
9499-040-82711 Building an engineering x c v For this purpose, we return to the soft-wiring mode ( hand pointer ) and click with the right mouse key on the function block for which we are setting the parameters.

9499-040-82711 III Function blocks: The KS98-1 function library contains all functions which are normally used for plant operation. These include: w w w w w w Functions for calculation of mathematic formulas from simple addition to exponent function Logic functions and functions for realization of control sequences Numerous selection and storage functions are helpful for signal processing. Alarm and limit value functions are indispensable for plant safety.
9499-040-82711 Not all inputs and outputs of a function block need to be connected. The following rule is applicable: open inputs are without effect. Examples: totalizer, multiplier, AND gate. In some cases, the connection of an input has an additional effect, if e.g. priority handling is concerned (programmer control inputs). Function blocks are numbered by the engineering tool in the order of occurrence from 100 to max. 450 as standard.

With a negative input variable x1, y1 = -1,5 w 1037 is set. g Note: LG10 is the reversal function of function 10EXP. Examples: The result of input value x1 = 63 is an output value of y1 = 1,799340549.

Description of KS 98-1 CAN bus extension 9499-040-82711 KS98-1 CAN communication features Every message on the bus activates the KS 98-1 interrupt handler and loads the processor. The message is analyzed and queued, if the destination of the message is the own address. This queue is handled in the idle task and during the cyclical system processing phase (at intervals of 100ms). 70% of the CPU capacity is reserved for the engineering. This time is considered as 100 % in the KS98 ET timing dia logue. I.e.
9499-040-82711 Description of KS 98-1 CAN bus extension RM 200 Data transmission in both directions is asynchronous. Data are transmitted only if changed (only the related PDOs). Checking, if changes were made is dependent on the accuracy of the data format (LSB). In both directions, the min. re fresh rate is 100 ms. Max. 5 PDOs + 1status PDO are sent by the RM node dependent on the number of modules in the nodes. Max. 5 PDOs are sent to the RM node by KS 98-1.

SDOs are used for asynchronous data exchange without real-time inquiry. Transmission started by the trigger input is always confirmed by the receiver, possibly during data inquiry along with value transmission. Reception of the confirmation is indicated by a logic 1 at the “ready” output.

Additionally, it permits adaptation by adjustment. Six parameter sets can be activated dependent on process criteria (process value, , correcting variable, control deviation), plant or batch characteristics. The parameter sets can be determined independently by self-tuning.

Controller III-16.5 9499-040-82711 Optimizing the controller Process characteristics Characteristics are determined automatically by the controller during self-tuning and converted into control parame ters. In exceptional cases, however, manual determination of these process characteristics may be necessary. For this, the response of process variable x after a step change of correcting variable y can be used (see Figure below).
9499-040-82711 Controller Direct / inverse switchover is always possible in configuration parameter CMode (action). III-16.6 Empirical optimization With missing distance data can empirically be optimized by means of the self-optimization or in manual attempts.
Controller 9499-040-82711 g For the controlled variable (process value X) the empirical optimization is substantially improved with a writer (or trend function of the engineering tool) in time requirement and quality, and evaluation of the test results is clearly simplified. g The procedure mentioned can only with restrictions be generalized and does not lead to a clear improvement of the behavior with all controlled systems.
9499-040-82711 Controller Configuration word OCond can be used to determine ‘Process at rest’detection. One of the following modes can be selected: Process at rest is detected, when x is constant. grad(x) = 0: grad(x) <0/>0: Process at rest is detected when x decreases constantly with a controller with inverse output action. Process at rest is detected, when x increases constantly with a controller with direct output action. grad(x) <> 0: Process at rest is detected with constantly changing x.
Controller 9499-040-82711 After successful self-tuning, the controller goes to the automatic mode and controls the using the new parameters. Parameter Ores indicates the self-tuning result (r see page 246) . finishing self-tuning with an error (Ada_Err), the stable correcting variable is output, until a When self-tuning is finished by the operator via system menu, front-panel key H , or via interface.

Controller 9499-040-82711 Controlled adaptation For defined applications, adaptation of the control parameter set to the current process condition is purposeful. For this, the Contr+ is provided with 6 control parameter sets, which can be selected via analog input ParNo .
9499-040-82711 III-16.8 PIDMA (Control function with particular self-tuning behaviour (No. 93) The controller block PIDMA is particularly suitable for difficult processes (with delay time, or of higher order). The dif ference between PIDMA and the CONTR block is only in the PID controller kernel (self-tuning and control algorithm). The additional functions ramp, switchover, override control, feed-forward control etc., which are described in the CONTR section, are not different.
9499-040-82711 The most important differences compared to controller functions CONTR and CONTR+ are: w Integrated, front-panel operated optimization method like PMA tune This function permits optimization also for difficult processes with Tg/Tu < 3 without engineering tool and laptop, which was not possible with previous PMA (and competitor) controllers. w w Parallel controller structure unlike all other PMA controllers with “serial structure”.

9499-040-82711 value before self-tuning can be detected by means of drift monitoring and taken into account when self-tuning is done for the next time. CSpeed can be used to determine if, during subsequent operation, the controller should reach the setpoint quickly, with a slight overshoot, or slowly with gentle approach to the setpoint. Using CSpeed , the parameter can be switched over also after self-tuning, provided that the controller parameters were not changed manually.
9499-040-82711 In the course of dynamic process control, the control algorithm can temporarily determine values below 0 or above 100 for the correcting variable. If necessary, however, these values can be reset to the limits by means of accelerated inte gral behaviour (Tsat). Tsat time constant for integral action in Y limiting (anti-reset wind-up). Self-tuning r controller adaptation to the process (PIDMA) Self-tuning can be started to determine the optimum parameters for a process.
9499-040-82711 Start in manual mode or in automatic mode : Basically, the PIDMA self-tuning algorithm does not distinguish between these two start conditions. In both cases, the operator must ensure that the process conditions are stable. In automatic mode, however, the PIDMA works with the non-optimized parameters until start of the correcting variable pulse. This means that, in the majority of cases, better stability of process conditions, i.e. better self-tuning results, are possible in manual mode.

Statuses during optimization The optimization statuses are displayed with priority in the display field for manual operation. Optimization running: Faulty optimization: display: display: Orun Oerr Fig.:72 Reglerseite bei gestarteter Optimierung.
9499-040-82711 Cascade operation is possible in the following operating statuses (see also section operating pages on page 36 ): w During automatic mode, the master variables ( and process value) are the relevant variables in the process. The master controller is directly adjustable. The process value of the slave controller is only displayed. " Cascade" is displayed. w Like every slave controller, the slave can be switched over to its internalsetpoint or to W2 via control inputs.
9499-040-82711 Manual operation Changing between automatic and manual mode is by pressing key H. The manual mode influences only the slave controller. The master is concerned only indirectly. The bargraph display switches over to slave variable Y. Adjustment of the correcting variable is via the value beside the bargraph.
9499-040-82711 III-16.12 Setpoint functions Terminology w we w2 Weff xw internal setpoint external setpoint second (internal) setpoint effective setpoint control deviation (x-w r process value - ) General Several possible setpoints are available. For the priorities, see the Fig. 77 drawing shown opposite. "Safety setpoint " w2 is given priority over the other setpoints. Switchover between setpoints is possible via interface or via the digital inputs of the conroller block.
9499-040-82711 External setpoint Wext Switching between the internal setpoint (wi) and the external setpoint (we) is possible only if the parameter WFuncis adjusted to W/Casc. The change-over can be triggered via interface or the digital control input we/wi. In order to make the internal setpoint effective, on we/wi must be attached a logic 1. If the external setpoint is to be active, a logic 0 must be given on we/wi. If the digital control input we/wi is not wired, the external setpoint is effective.
9499-040-82711 Controlling the setpoint The digital input rstart reacts to a positive signal slope and sets the effective setpoint to the process value. The new goal is started on the basis of the controlled variable xeff. Such a ramp can only be started with activated gradient function (Grw+, Grw -, Grw2 and digital input gr_offnot set). The digital input w_stop freezes the effective Weff , i.e.
9499-040-82711 Process-value tracking It can occur that the is far distant from the momentary process-value (e.g. when starting a plant). In order to prevent the jump developing here, the function process-value tracking can be used. Process-value tracking causes a take-over of the process-value on the internal setpoint , when changing over Wext r W. When shifting (W back r Wext) Wext is started with the attitude of Grw+/- (see rFigure below).
9499-040-82711 Controller-internal operations during switch-over with CONTR, CONTR+ and PIDMA Switch-over Without gradient function With gradient function After correcting variable adaptation with deletion of a still effective derivative action, the approach to the setpoint is bumpless The effective setpoint ramp continues running in the background during manual mode.
9499-040-82711 Controller parameter “a” can be used to define at which distance to the final setpoint the target orientation should be switched over to the final setpoint. The target line-out function is activated under the following conditions : 1. 2. 3. W < Wend W > Wend-2a X > Wend-a Fig. 84 Marginal conditions / restrictions: With internal setpoint ramps, the controller knows the future target setpoint.
9499-040-82711 For optimum combustion, the fuel-air ratio must be controlled. With stoichiometric combustion, the ratio is selected so that there are no inflammable residues in the waste gas. In this case, the relative rather than the physical ratio is dis played as process value and adjusted as setpoint. If the transmitters used by the controller are designed with a stoichiometric ratio, l = 1 is met exactly with restless combustion.
9499-040-82711 Ratio = Type 2 W= X 1+ N 0 ( X 1 + X 2 )× SFact Fig. 87 w = (x1+N0) / (x1+x2) w SFac In this example, water (x1) must be batched as a percentage of the total (paste; x1+x2). As the paste quantity is not available directly as a measurement signal, the total is calculated internally from x1 and x2. N0 = 0 must also be adjusted in this case. X1 X2 x1 Water Dough x2 Flour Ratio = Type 3 W= X 2- X 1+ N 0 X 2× SFact Fig.
9499-040-82711 Second correcting value Similar to processing, switch-over to a second preset correcting value Y2 is possible. Switching over is done via digital input y/y2. Whether Y2 has safety functions, or whether it is only a pre-defined start position in defined process conditions is determined only by the use and integration into an automation concept. correcting value Y2 is evaluated with priority.
9499-040-82711 Limiting control Limiting with continuous output. Limiting control with three-point stepping output can be realized by using a continu ous controller with the OVC function. A position controller (three-point stepping) provides override control. Fig.: 96 Limit control with continuous controller Override (limiting) control using a three-point stepping output Override control is also possible by means of a classical three-point stepping controller.
9499-040-82711 Which one of the two controllers influences the process is decided in the slave controller logic. The first “close” pulse coming from the limiting controller switches over to override control. The limited controller automatically retrieves the positioning authority, when it first tries to close the actuator further. Bumpless auto/manual switch-over Sudden process interventions by control mode switch-over are usually not desired. Excepted is purposeful switch-over y r Y2.
9499-040-82711 III-16.14 Small controller ABC Some operating principles, which are realized in the controller (d) or which are possible by means of an additional engineering are explained in the following section (ü). Cross references are shown in italics. Anti-reset-wind-up Measure which prevents the controller integrator from saturation. Working point (Y0) The working point of a P or a PD controller indicates the value output to the process with process value = .
9499-040-82711 Hard manual (sm/hm) Safety output value Yhm. The controller output goes to the preset value immediately, when hard manual is active (the controller is switched to manual mode directly). Keys I / D are without effect. Switch-over to automatic mode is bumpless. Cascade control Particularly suitable for temperature control in e.g. steam boilers. A continuous master controller (load controller) provi des its output signal as an external to a slave controller, which varies the output value.
9499-040-82711 Soft-Manual Usual manual operation: with automatic r manual change-over, the last output value remains active and can be adjusted via keys I / D. Transitions automatic r manual and vice versa are bumpless. switch-over In principle, the following s are possible: internal wi, second internal w2 and external we. With program control, external we must be selected. The analog comes from APROG and is applied to input Wext.
