1 System Calculator (on Control Module Level)

1.1 Principle of program set-up

As it would be a too high effort to realize a comfortable mathematical formula system we created a syntax which is easy to input and easy to realize. As we assume that customers or service people have to set-up the program only one times for an installed system it should be acceptable to realize a form which is only done by inputting numbers.

Therefore we have mainly to differ between positive and negative numbers. The program operations are assigned with negative numbers. The operands which are used by these input operations are positive numbers. These positive numbers symbolize signals which are part of a signal pool.

Also we have to know that there are used different classes of operands. That means we have different classes of signal pools.

Those are:

• Live values (real measuring values)

• Constant values

• Memory values.

In each of these classes exists an own numbering and we determine by the operator itself which class of these operands is meant.

Remark:

Opposite to former versions allowing calculator function within ONE TFID/MLT/CAT 200 analyzer module (AM) or for ONE TFID/MLT analyzer (or CAT 200 analyzer resp.) ONLY now the system calculator is based on the C

ontrol Module level (CM). This allows to include ALL analyzer modules resp. MLT channels of a NGA 2000 analyzer system into the calculation. The results of the system calculator can be put onto the 2-8 analog outputs of the programmable Input/Output Module SIO. The SIO as a Control Module I/O is then located in a platform or in a TFID, MLT or CAT 200 Analyzer.

HAS55E03IM11S(1) [NGA-e (TFID software 3.7.x)] CM Calculator Page 2

Calculator on Control Module Level

In the following table we find all the currently available operators (negative numbers) and their meaning. Hereby is used the acronym "IR" for the actually calculated intermediate result of the program.

Table 1-1: The Operators of the System Calculator

Operator number

-10 SUBM m subtract following memory value operand from IR (IR = IR – m)

-11 DIVM m divide IR by following memory value operand (IR = IR / m)

-12 MULM m multiply IR with following memory value operand (IR = IR * m)

-13 STOM m store IR at following memory value and set IR = 0.0 (m = IR; IR = 0)

-14 STOR r store IR to following result and set IR = 0.0 ( r = IR; IR = 0)

-15 NOP no operation (placeholder)

-16 ABS convert IR into absolute value (IR = |IR|)

-17 EOP end of program

-18 SQRT

-19 NEG negate IR (IR = -IR)

-20 INC increment IR (IR = IR + 1)

-21 DEC decrement IR (IR = IR – 1)

-22 INV invert IR (IR = 1 / IR)

-23 EXP exponential function (IR = eIR)

-24 POWM IR raised to the power of the following memory value operand

-25 IF> m1 m2 m3 if IR > 1st following memory value

-26 IF< m1 m2 m3 if IR < 1st following memory value

-27 IF= m1 m2 m3 if IR = 1st following memory value

-28 LN natural logarithm (IR = ln(IR))

-29 LOG base 10 logarithm (IR = log(IR))

Acronym Description

1.2 Live values (real measuring values)

In the platform calculator we have a signal pool of momentary up to 25 possible live signals. The first 10 signals in this pool are fix assigned the rest of the signals are free assignable.

Table 1-2: Live Values Pool

Number Assignment assignment type Signal 1 Result 1 fixed

Signal 2 Result 2 fixed Signal 3 Result 3 fixed Signal 4 Result 4 fixed Signal 5 reserved fixed Signal 6 reserved fixed Signal 7 reserved fixed Signal 8 reserved fixed Signal 9 reserved fixed Signal 10 reserved fixed Signal 11 MLT 1/CH1 Concentration programmable Signal 12 TFID Concentration programmable Signal 13 MLT 2/CH3 Temperature programmable Signal 14 TFID Temperature programmable Signal 15 not assigned programmable

.... ........... programmable

Signal 25 not assigned programmable

By using these numbers of the signal pool we determine the live value operands in the calculator's program.

Example of a calculator program with upper signal assignment:

Result 1 = (MLT 1/CH1 Concentration) + (TFID Concentration)

Step (o+1) -1 ADD (at beginning the intermediate result IR = 0) Step (o+2) 11 Signal 11 (here: MLT1/CH1 Concentration) Step (o+3) -1 ADD Step (o+4) 12 Signal 12 (here: TFID Concentration) Step (o+5) -14 Store IR to result Step (o+6) 1 Result 1 Step (o+7) -17 End of program

HAS55E03IM11S(1) [NGA-e (TFID software 3.7.x)] CM Calculator Page 4

Calculator on Control Module Level

1.3 Constant values

The same principle is used for the constant values. We have a pool of free assignable constant values.

Example of a constant signal pool:

Number Assignment Constant-1 1.000000

Constant-2 10.00000 Constant-3 100.0000 Constant-4 1000.000 Constant-5 10000.00

.... ...........

Constant-21 500.0000

By using the numbers of the signal pool we determine again the constant operands in the calculator's program.

Example of a calculator program with upper live signal and constant assignment:

Result1 = (MLT 1/CH1-Concentration) + 100

Step (o+1) -1 ADD (addition by using the live operand's class) Step (o+2) 11 Live value number 11 (here: MLT1/CH1-Concentration) Step (o+3) -5 ADDC (addition by using the constant operand's class) Step (o+4) 3 Constant number 3 (here: 100.0) Step (o+5) -14 Store IR to result Step (o+6) 1 Result 1 Step (o+7) -17 End of program

1.4 Memory values

The same principle as in constant values is used again for the memory values. We have a pool of usable memory places where intermediate calculation results can be stored to.

The single signals of the pool (selected by 'Signal number') are assigned by first selecting the source analyzer module (AM) resp. analyzer channel of the requested signal and then the signal name itself. Please, note that is only possible to modify the programmable type of signal numbers.

To realize the signal name's selection there is used an already implemented feature of the AMs. It has being used for the small bar graphs display and for the analog outputs of the SIO module. It is the SVCONT/SVNAME variable mechanism. This mechanism provides the possibility to have a link to the LON variables of an AM which are listed in the SVCONT enum. In the SVNAME variable are listed the related human readable strings.

If we want to assign the signals not via the menu but via LON variable access we have to do the following steps:

1. Enter signal number by setting CALCSIGNUMC.

2. Enter the source of the signal by setting CALCSRCC to the TAG-variable's string of the requested channel.

3. Set CALC_ENTRYSIG (instead of using CALCSIGC) to the enum value that the signal has in the SVCONT-

variable.

Picture 1-5: Programming the System Calculator

If we want to assign the signals not via the menu but via LON variable access we have to be aware of following:

1. The PLC-programming as well as the programming for the system calculator happens indirectly via the edit

variable-array ED_INTx. To differ what the programming is for there exists the LON variable PROGTYP. Setting PROGTYP = 0 means we want to program the system calculator. Setting PROGTYP = 1 means we want to program the system PLC.

2. By using the variable LISTOFFSET we determine what part of the whole programming list we want to

program. For example, setting LISTOFFSET = 60, means by usage of ED_INT1...ED_INT10 we are able to modify the program steps 61...70.

2 Display Calculator Results on Mini-bargraph

In order to show the calculator results on the mini-bargraphs of the single component display we overworked the architecture of the bargraph displays.

All the signals which are shown on this display in the versions up to now belonged always to the selected component, that means they belonged all to the same AM-channel or to an I/O module which is bound to it.

To show a calculator result which belongs to the CM we have to assign signals of a different node/subnode to the single component display's bargraphs. Therefore we have chosen a way which enables us to do a complete free signal assignment.

Also we are able to set-up the calculator result's unit and its range limits.

And finally we are able to assign an own signal name to the bar graphs. Up to now there have been shown the name that is noticed in the SVNAME variable. For most of signals this is sufficient. But especially for signals which have no unique function (like calculator results) we want to show configurable and therefore more intuitive signal names.

By inventing this new bargraphs display structure we also looked to have a behavior which can fulfill the current functionalities. Therefore we created the possibility to assign signals of I/O modules and their implemented SVCONT/SVNAME signals as well as the ANALOGOUTPUT/ANOPUNITS variable of older I/O module versions.

2.1 Display mode

For each selectable component we can compose bar graph displays. This composition can show signals of a prepared pool from any attached network node. To have the possibility of being compatible to current software versions we create also a mode which displays the signals as they are selected by the analyzers itself.

Calculator on Control Module Level

By use of the four "Display mode for line x"-parameters we select the handling of the 4 bar graphs.

Disabled: The bar graph is switched off. AnalyzerSelected: The bar graph receives the signal from the SVNAMEx-variable of the selected component

module (AM). This is the already implemented and mainly used mode. PlatformSelected: The bar graph receives its signal from a signal pool that is installed in the Control Module itself.

2.2 Assign signals and convenient names

If we use the 'PlatformSelected' signal mode we have to determine what signal number of the pool has to be displayed. The selection of this number is performed in the appropriate menu line "Signal number for line x".

Now we have to determine only what kind of signal is behind each signal number of the pool. This is done in the following menu display.

fct3: AUXLIST_

We are able to assign signals which come from all installed nodes/subnodes and have the SVCONT/SVNAME variable. Further more we present I/O modules which have the ANALOGOUTPUT / ANOPUNITS variable.

The procedure is the following: First we select the signal number we want to assign the signal for. Then we choose the source (node/subnode) the signal shall come from. After this we choose the signal itself of the selected source.

With the "Signal description" parameter, which is an editable string variable, we create the ability to give a convenient signal name to each of the assigned signals.

If we want to assign this not via the menu but via LON variable access we have to do the following steps:

1. Enter signal number by setting SGNSNUMC.

2. Enter the source of the signal by setting SGNSRCMODC to the TAG variable's string of the requested

channel.

3. Set SGN_ENTRYSIG (instead of using SGNSRCSIGC) to the enum value that the signal has in the

SVCONT variable.

4. Enter the signal description by setting SGNDESCRC.

3 Assignment to SIO Analog Outputs

The assignment of the system calculator results to an analog output of the SIO board is realized by extending the selectable module types. Now it is also possible to select the platform itself with its own signals (calculator results).

That means we have added the SVCONT/SVNAME variable for node/subnode 0 (platform). Here we assigned then the new CALCxRESULT variables of the system calculator.

2 Principle of Program Setup

As it would be a too high effort to realize a comfortable mathematical formula system we created a syntax which is easy to input and easy to realize. As we assume that customers or service people have to setup the program only one times for an installed system it should be acceptable to realize a form which is only done by inputting numbers.

Also we have to know that there are used different classes of operands. That means we have different classes of signal pools.

Those are:

• Input signals

• Output signals

• Actions.

In each of these classes exists an own numbering and we determine by the operator itself which class of these operands is meant.

Remark:

Opposite to former versions allowing PLC function within ONE TFID/MLT/CAT 200 analyzer module (AM) or for ONE TFID/MLT analyzer (or CAT 200analyzer resp.) ONLY now the system PLC is based on the C M

odule level (CM). This allows to include ALL analyzer modules resp. MLT channels of a NGA 2000 analyzer system into the PLC system. The results of the system PLC can be put onto the programmable Input/Output Modules SIO or DIO. The SIO or DIO’s can work as Control Module I/O’s being then located in a platform or in a MLT, CAT 200 or TFID Analyzer but also as local I/O’s in (remote) TFID, MLT or CAT 200 analyzer module.
