2. Function Block Programming

The α2 Series Controller is programmed with a user-friendly method of combining specialpurpose dedicated function blocks. The task is broken down into various stages which can be

represented by a number of function blocks. Function Block Programming simplifies application representation but ensures complete process control. The program can be developed in very simple steps but even a complex task can be represented in this way. For ease of use, the function blocks have been preprogrammed to perform certain tasks yet offer flexibility to be tailored to individual requirements.

necessary control for the application according to the system algorithm. Each function block provides specific control parameters, accessible by the user, to tailor each program for complete application suitability. The function blocks are connected together to form a circuit using the Function Block Diagram (FBD.)

2.1.4 Function Blocks

Programming the α2 Series Controller is based upon the combination of different function blocks. They process the information received from the previously mentioned inputs and control the system Outputs. They can also provide input signals or information to other function blocks using word outputs pins. To make programming easier, the Function Blocks have all been preprogrammed. However, parameters within each function block dialog box can be set according to the intended application.

3.6.10 Analog Inputs

The Analog Inputs can be configured for three different modes: Normal, TC and PT100. Normal mode is used for ordinary analog signals. TC and PT100 modes should be used with the AL2-2TC-ADP and AL2-2PT-ADP modules respectively. For more information on these modules, refer to the Alpha Hardware Manuals and the individual installation manuals. The following changes should be made in the Stop mode. Only the “OffsetFine” adjust works in both RUN and STOP modes.

To Set/Change the modes of the Analog Inputs (Stop Mode only):

1 ) Select “Others...” from the TopMenu while in Stop Mode. 2 ) Select “Analog In.” 3 ) Choose the appropriate input and press OK. 4 ) “Mode” will be the only option displayed if the analog input was previously set on “Normal.”

Select “Mode” by pressing the OK button. Then, select the appropriate mode setting. “Calibrate” and “OffsetFine” should appear on the Analog Input settings menu.

Offset Calibration of the PT 100 and TC inputs (Stop Mode only):

3.8 Block Items

Each block item contains an individual diagram that shows the block number, available number of input pins, the output pin if applicable, and the block mnemonic. Connections between blocks can be viewed at the pin locations when connected blocks are shown individually on the LCD.

3.8.1 Input Blocks

The Input Blocks consist of System Inputs (I01 - I15), Key Inputs (K01-K08), and System Bits (M01-M14). The input number is shown in the top right hand corner, the type of input in the lower right hand corner, and the output pin is shown on the far right of the block. Input Blocks provide information to the Function Blocks or Outputs.

3.8.2 Function Blocks

The individual Function Blocks are described in detail in Chapters 5 and 6. Function Blocks can have 0 to 4 input pins shown on the left of the diagram and an output shown on the far right. Some function blocks have data that can be used for comparison purposes only or are used to display data onscreen. These blocks have no output pins. The number and block mnemonic are shown in the top right and bottom right locations respectively.

System Menu 3

3.8.3 Output Blocks

Output Blocks have one input and one output pin. They only have the capacity for one input signal through the input pin. The Output Block number and Mnemonic are shown in the top right and lower right hand corner of the diagram respectively.

3.8.4 Connected Blocks

Blocks that are connected can be shown simultaneously onscreen. The block providing the output signal will be shown on the left of the screen. The input pin accepting the signal will flash. Any input pin that is already connected will be shown as a solid triangle.

The α2 can be programmed using the front panel keys on the α2 series controller. When the function block diagram is complete, the program can be logically entered into the

following sections will describe how to connect/disconnect function blocks, set program parameters, add Function Blocks, and move around within the program.

The ProgEdit mode in the Stop Menu has full programming capability. The Monitor mode in the Run Menu has the capability to manipulate Function Block values and settings but cannot edit, change, or delete the existing program.

4.1 Block Availability

The number of System Inputs and Outputs is determined by the type of controller being programmed. Configurations include 8 In / 6 Out and 15 In / 9 Out. Up to 200 Function Blocks can be used in a program or 5000 bytes of memory. The Function Blocks must be added in the course of programming. The 8 Keys and the 14 system M bits are automatically available for every program. Inputs, Outputs, System Memory Bits, Extended Inputs, Extended Outputs, AS-i Outputs, Control Bits, and Keys do not count in the Function Block total.

4.2 Connecting Blocks

Any block that has an output pin can be connected to any block that has an (unused) input pin. System Inputs, Keys, and Memory M bits have output pins only. Function Blocks and Outputs both contain input and output pins (the Display and TimeSwitch Blocks are exceptions). Blocks can be connected beginning with an output pin, from “left to right” on the display, or beginning with an input pin, from “right to left” on the display.

4.2.1 To connect the blocks from the left (signal provider) block to right (signal receiver) block.

It is necessary to choose the block to provide the output (step 1), the block to accept the signal (step 2), and the pin with which to accept the signal (step 3).

1 ) Step 1: Select the block providing the data to be output and move to the right until the

output pin is flashing. Press the “+” button to “add” a block.

When connecting a Function Block, scroll to the AddFB prompt and press the “OK” key. This invokes the Function Block list. Scroll to the desired Function Block and choose by pressing the “OK” key. The Function Block will be shown on the screen with the connecting block.

4.5 Function Block Editing

To enter the Function Block editing menu (Chapter 3), press the “OK” key when the Function Block number and name are flashing on the screen. Up to three options appear on-screen: Setup FB, Change No, and Delete FB. The Setup Function option is not valid for some Function blocks and so will not always appear and certain function blocks will also contain a Time unit option (refer to chapter 6 for function block specification).

4.5.1 Setup Function Block

Each Function Block has its own individual parameters outlined in Chapter 6. The Function Blocks might have multiple data screens that can be altered. As with other menu options, the “ESC” key will move the screen back to a higher menu option without changing the option parameters for that screen. If there are multiple data screens in an option, enter the required data and accept each screen using the “OK” key. Use the “ESC” key to exit the Function Block.

4.5.2 Change No. (of a Function Block)

Change the number of an existing Function Block with this screen. The current FB number is shown on-screen when the option is selected. Scroll up or down with the “+” or “-” keys to find an open FB number. Press the “OK” key to accept the new number.

4.5.3 Delete FB

This menu option will Delete the current Function Block. After the Delete FB is chosen, confirm the delete operation with “OK” or use the “ESC” key to cancel the function. All connections to the Function Block will be removed with the block.

4.6 Movement between Function Blocks

There are a number of ways to move from one item to another when in the ProgEdit or Monitor modes.

4.6.1 Movement Between Unconnected Blocks

Movement between System Inputs, System Outputs, Keys, and M bits can be accomplished with the “+” and “-” keys. When the block number is flashing on-screen, press the “+” key to scroll to the higher value of the same block type; e.g. move from I01 to I02 to I03...until the highest value is reached. The scroll will then proceed to the lowest value of the next block type. The same technique will work for the “-” key in the opposite direction. Function Blocks can be scrolled through in the same manner, although only the Function Blocks are rotated through in this case.

4.6.2 Movement Between Connected Blocks

The Right arrow moves horizontally (to the right) along the path of connections between blocks. If an output pin is connected to multiple input pins, the current path will flash. The Up and Down arrows can be used to choose the desired path. The left arrow will move back along the path of the connections to the left.

Direct Programming 4

4.6.3 The Jump Command

The “ESC” key can be used to enter the Edit Menu at anytime when a function block is displayed on the LCD screen. (The “ESC” key will cancel in-process commands first. Keep pressing the “ESC” key until the Edit Menu is displayed). Select the Jump Command. Choose any system M O

utput, or existing Function Block by using the front panel keys. Press “OK” to “Jump” to the

emory Bit, Input, Output, Key, AS-i Input, AS-i Output, Extended Input, Extended

chosen block in the programming mode.

4.7 Using Keys as Inputs

Connect the Keys for use as Manual Inputs by using the Jump command to access the desired key, by connecting a Function Block or Output as described in Chapter 3, or by scrolling through the blocks as described in section 4.6.1. The programmed Key(s) will give an output signal for as long as the key is depressed.

5. The Logic Function Blocks

Logic Function Blocks operate by reading whether signals are ON or OFF and then setting the status of their Outputs accordingly. There are six types of logic blocks available in the Series - AND, OR, NAND, NOT, NOR, XOR. Analog signals cannot be processed by the Logic blocks. In this chapter, each Function Block has a description, a diagram of the Function Block as seen on the LCD Display, and a logic table to show how the Output is controlled by the input signals.

The α2 series controller is fundamentally based on function block programming. The blocks provide a wide range of possible operations and have been preprogrammed for ease of use. Some Function Blocks have parameters that can be tailored to meet individual requirements in the programs. Each function block will have a description of the Block’s purpose, a diagram of how the Block will appear on-screen, and a description of the inputs, outputs, and available options.

6.4 Set/Reset Block

The function block will set or reset an output according to the input condition. When the SET input is energised, the Output is ON. When the RESET input is energised, the Output is OFF. When both inputs are energised simultaneously, the Output will follow the Priority Setting signal. A latched Output does not depend on the constant signal to retain its status. Set Priority - When the Set input comes ON, the Output comes ON and remains ON until the Reset pin receives a signal. Once the Output is ON, the Set input signal can turn OFF without effecting the Output. If both the Set and Reset pins are ON, the Output is ON.

Reset Priority - The operation is the same as the Set Priority except that when both pins are ON, the Output is OFF.

6.7 Delay Block

The function block delays the signal to an output for a set length of time. The On or Off delays can be set individually or in combination. Ex. The On Delay Time is set to 5 seconds. The Delay Block Input signal comes ON; five seconds later the Delay Block Output will come ON. The Output signal stays ON as long as the Input signal is ON. The Output signal turns OFF at the same time the Input signal turns OFF. The Clear Input will turn the Output OFF and cancel the current operation. The Clear pin over-rides the Input pin if both signals are ON simultaneously. The On Delay option will delay the Output from turning ON for a set time after the Input comes ON. The Off Delay will delay the Output from turning OFF for a set time after the Input has turned OFF.

6.14 Analog Output

The digital value on the word input pin is converted to a corresponding output voltage or current on the specified channel on the AL2-2DA module. One of two output modes can be selected, voltage or current output. In voltage output mode, digital values from 0 to 4000 are mapped onto analog values from 0 to 10 volts. In the current voltage mode, digital values from 0 to 2000 are converted to a range of 4 to 20 mA. If a digital value less than the lower limit of 0 is input on the word input pin, the analog output will default to the lower limit of the analog range (0 V or 4mA) for the specified output mode. If a digital value greater than the upper limit is input, the analog output will default to the upper limit of the analog range (10V or 20mA) for the specified output mode. The acceptable data types for the word input pin are constants, analog inputs or FB output values. When more than one Analog Output FB is configured to use the same channel, all FBs will be executed if their enable pins are active. The FB that is executed last in the program will control the operation of the AL2-2DA board. The user cannot know which FB will be executed last due to lack of knowledge of the controller’s processing algorithms. Care should be taken to avoid situations in which two or more analog output function blocks may conflict.

When the High Limit value is larger than the Low Limit value, the output will turn ON when the High Limit value is reached or exceeded. The Output will turn Off when the Input value is equal to or less than the Low Limit. (The Output does not turn OFF when the Input Value falls below the High Limit), eg. an air conditioner is set to turn ON when the air temperature reaches 23 reaches 18 temperature fluctuations.

When the High Limit value is less than the Low Limit value, the Output ON/OFF pattern is reversed. When the Input Value is greater than or equal to the Low Limit Value, the Output turns OFF. When the Input Value is equal to or less than the High Limit value, the Output comes ON. The input pin must be ON for the Function Block to register a new value from a Function Block or Analog Input. Therefore, the input pin must be ON for the status of the Output to change. The input pin does not have to be ON for the Output to be ON.

6.19 Hour Meter Block

The Hour Meter is used to track the amount of time that a device has been in operation. This can be very useful for preventative maintenance schedules or for performing feasibility studies. The timing starts at the receipt of an Input signal and retains the accumulated time through system shutdowns or power failures. When the Set Time value is reached, the block Output will turn ON. The Hour Meter will continue recording time after the Output time is reached. A signal to the Clear pin will reset the current time value to zero.

6.20 Speed Detect Block

The function block measures the signal input frequency for a set user defined period of time. The frequency is constantly compared to a preset high and low threshold values and the output is set ON if the conditions are satisfied. The speed detect function block is used to count incoming pulses, however, for normal inputs without the AL2-4EX expansion module connected the incoming pulses are restricted to 20Hz. The AL2-4EX, with inputs EI1 or EI2, expansion module allows for 1KHz incoming pulses to be measured.

Function Blocks 6

The function block counts incoming pulses when the input is ON. When the input signal is OFF, the actions to count the pulses of the counter input and compare the speed with upper and lower threshold limit will stop.

1) Speed and output values will not be cleared unless the clear pin receives a signal to reset the counter.

2) Upper limit> Lower limit: The output signal will be OFF when the speed output value is equal to

or less than the lower limit value. If the speed output value is equal to or larger than the upper limit value the output status will be ON. Otherwise the output signal does not change.

3) Lower limit > Upper limit The output signal will be OFF when the speed output value is equal to or larger than the lower limit value. If the speed output value is equal to or less than the upper limit value the output status will be ON. Otherwise the output signal does not change.

4) Lower limit = Higher limit The output status is ON if the Speed Output = Lower limit = Upper limit. Otherwise the output signal is OFF.

5) Function Block data: a) Period setting value: 1 to 32767

Output status: refer to the speed detect time charts for output status.

1) The following items are available for other function blocks: a) Set Period b) Current Period

Note: The Speed Detect function (SPD) block can use only 1 high speed frequency (Max.1kHz) in any one program. Subsequent SPD function blocks can only use a maximum of 20Hz for high speeding counting.
