  11. Programming Overview Basic programming features Software Available instructions RETURN

  12. Basic programming features • Function (block) based programming • Programming directly from the front of the Alpha • Graphic LCD-Display • 8 keys • Menu driven operation • System operation available in 5 languages(English, French, Spanish, German, Italian) • All information of one function block is displayed simultaneously • Option - Windows based software (95, 98, NT)

  13. Programming directly from the front Monitoring Menu driven operation LCD-Display & 8 keys All function data displayed simultaneously

  14. Programming basics • Programming is function (block) based • Each function is easily selected • Each function (block) carries out one task which has a number inputs conditions and resultant outputs • Up to 64 function scan be linked together (or up to 1500 bytes - which ever is exceeded first) • Each function (block) can be used as many times as required Analog values / special outputs / display outputs Digital input Digital inputs Digital output Analog input

  15. Software - ALVLS • The software is called AL-PCS/WIN (ALVLS - Alpha Visual Logic System) • ALVLS works under 95, 98 and NT • ALVLS is a graphic based software which is available in 5 different system languages (English, French, Spanish, German, Italian) • Programming is possible with no previous experience • There is a system Wizard (to help create basic programs) • There are on line guides (to help use software functions) • Programming is based on selecting graphic icons which represent functions, placing them in a work area and connecting them up with a line. • There is an extensive help system (to provide general support)

  16. Software - ALVLS • Icons can be personalised, I.e. users can add or customise their own • All programs can be simulated: • On-line simulation and monitoring requires the Alpha unit to be connected to the PC • Off-line simulation requires no Alpha unit as everything is self contained in the ALVLS software • ALVLS programs can be completely documented with comments for functions and added generic comments • ALVLS has a “system sketch” mode which allows users to create their own PC based operator interface

  17. Software - ALVLS

  18. Software Input signals • Automatic identification of digital or analogue inputs depending upon the selected input image Internal Bits Input menu selection Buttons Inputs Scroll selection

  19. Software Input signals • Analogue signals • Up to 8 inputs can be defined as analogue • Analogue input is 0 to 10V DC • Analogue resolution is 8 bits (0 to 255) • Analogue inputs are only available on 24V DC powered units Analogue signal is shown with a thicker connection line Example, AnalogInput Analogue or special signal is represented by green dot

  20. Software Output signals • Graphical symbols and images make programs easier to understand Output menu selection Output types Scroll selection

  21. Software graphical program simulation • Programs written with ALVLS software can be simulated to ensure correct operation. Input/Outputs status is toggled with line and function block status.

  22. Instructions - Logic signals • Simple boolean commands OR(Or-Link) AND(And-Link) NOT (Negation) XOR (either/or) NOR (Or-Link negated ) NAND(And-Link negated)

  23. Instructions - Logic signals • Complex boolean instructions can be created using the BOOLEAN function Easy to understand ‘sentence’ construction Word or symbol logical operators Simulation

  24. Instructions - Status control • Self retaining command SET-RESET: • SET (set), RESET (set back) • Setting of priority • Status alternate (flip) ALT: • It function toggles the output whenever the input signal changes from OFF to ON. When clear input is ON, output becomes OFF irrespective of input status. • Time-function ONE-SHOT: • Time range 0.1 s–6553.5 s • This function is used to generate a single pulse with a specific duration

  25. Instructions - Status control • Time function DELAY: • Time range 0.1 s–6553.5 s • Switch on-delay (on-delay) • Switch off-delay (off-delay) • Switch on- and off-delay timer,duration's can be set separately • Pulse generator function FLICKER: • Time range 0.1 s–6553.5 s • Pulse generator asymmetric(T-on, T-off individually adjustable) • Number of pulses adjustable or continuously • Total time of pulses adjustable or continuously • Time function PULSE: • Generates a pulse for one cycle when thefollowing are selected: • leading edge of one input • trailing edge of one input • leading and trailing edge of one input

  26. Instructions - Event monitoring • Maintenance function HOUR-METER: • Next maintenance time is set - when reached an output is activated • Counting of working hours and minutes up to 32767 hrs and 59 min (1365 days, 3.7 years) • Counter value kept for 20 days after power is removed • Can be cascaded to increase time base • Counter function COUNTER: • Counting range up to 32767 • Output set when Count value reached • Count can be reset by input at any time • Counter function UP/DOWN-COUNTER: • Counting range: -32767–+32767 • Up/Down inputs are separate • Output set when Count value reached • Count set value can be manual setting, analogue input or fixed value triggered by digital input • Count can be reset by input at any time

  27. Instructions - Event monitoring • Real time clock function CLOCK: • Data available from the real time clock: hours, minutes, day of the week, day of the month,month, year • 3 Formats to display the date: mm.dd.yyyy • Direct adjustment of the clock on the unit • Automatic adjustment of day and week • Automatic summer time/daylight saving time(US, UK, EU presets plus user configured option) • Max. 350 time events Example : Tuesday, 08.02.1999 10h30 08.02.1999 02.08.1999 1999.02.08

  28. Instructions - Value processing • Analogue value processing GAIN: • Adjust Gain/Offset of read analogue values • Apply scaling to analogue input values • Compare-function with words COMPARE: • Comparison of 2 values (could be analogue, counter or timer values) • Types of comparison: =, <>, >, >=, <, <= • Schmitt-Trigger SCHMITT • Comparison of a value to 2 set pointstriggering different actions • Zone Compare (range on/off) ZON-CMP • Comparison of a value to a range(could be analogue, counter or timer values) • Types of comparison: =, <>, >, >=, <, <=

  29. Instruction - User Interaction • HMI-Function DISPLAY: • LCD-Display on Alpha: 4 lines x 10 characters • The contents of display can be freely programmedwith text and/or values from programmed functions • Displayed values can be easily changed/edited usingthe keys on the front face of the unit

  30. Instruction - User Interaction • To change a value through the HMI/Display option: • Press key: • First value is signaling • +1 at value, key • -1 at value, key • Confirming of change, key • Should the display consist of several values, selection of values with or with

  31. System sketch RETURN

  32. System sketch • ALVLS software, “Monitoring in System Sketch”: • In the ALVLS software it is possible to carry outmonitoring and/or simulation • Within the System sketch area, users can create avisual representation of their application(effectively creating a low function SCADA system) • Images can be imported (BMPs) and links to standard Windows programs can be made • User’s can copy any of the inputs/outputs or functionsused in the Alpha program to the System sketch area • By placing the devices in the System sketch and then activating either the simulation or the monitor mode’s - the users program can be controlled directly E.g………………..

  36. Ancillary Items • Memory cassettes: • By insertion of an EEPROM-cassette a new Alpha program can be directly inserted without aprogramming tool • Alpha has been designed to suit users needs: • Industry (IEC 1131.1, 2) • House- and building technique (EN 60730) • CE EMC • CE low voltage • UL/cUL.
