The blocks are elements used in Logic Builder that, interconnected, build routines and programs.

The blocks are divided in the following categories.

Start routine

Program Variables

Macros

Operation blocks/ Built in blocks

Start Routine

This is a block found on all routines and programs. Its purpose is to mark the start of a routine, 

If the routine is set to run On Event, the block will also include a Condition port. This is useful when the routine  needs to run if some conditions are met. The condition can be  a Get block, a macro or an operator block

Program Variable Blocks

These are blocks that provide data (for example a temperature sensor).The variables present 2 blocks, a Get and a Set block.  

The Get block can be used as a condition on a runtime. An example is this Alarm Routine where roomTemp get is used as a trigger for the alarm.

The Set block is used to write  a value following meeting a condition, which can be a block or an entire routine. It can also be used as a condition on itself

Like variables, variable blocks are color-coded by type as follows:

Number - Purple

Boolean - Green

String - Gold

Time/Date -Teal

Number Blocks 

These blocks are representations of number type variables. The Set Block can be completed with a numerical value, either manually or via a routine.

Boolean Blocks

These blocks are representations of boolean type variables. The Set Block can be completed with a true or false value, either manually or via a routine.

String Blocks

These blocks are representations of string or enum type variables. The Set Block can be completed with string values, either manually or via a routine.

Time/Date Blocks 

These blocks are representations of date or time type variables. The Set Block can be set to a point in time or on a calendar date.

Macro Blocks

These are  special blocks that can contain entire routines or expressions (double-clicking on a macro in the Variable/Routines will open a new workspace). These  blocks are coloured dark blue 

Built in blocks

These are  presented in the Block Library. These are used to channel conditions and commands between other types of blocks. These are coloured grey.

To  lookup a block  in the library,  users can either look them up using the search bar or  can 

The complete list of built-in blocks is presented below.

Commands

condDelay- Add delay to condition after a transition from false to true before evaluating to true. Units to use are: sec, min, hr

email - Send an email using the configured SMTP connector. More details about this block here.
setDelay - Variable set with a delay. It only delays if there is a change of value on the set block. Setting same value will not make it delay. Recommend to use wait block instead for static set value.
setExternal - Variable set from an external program
wait - Pause the routine for a specific amount of time. Units to use are: sec, min, hr, and day?

Control Flow

if - If block performs boolean condition flow control between then and else. If Block example.
return - Return exits the routine and returns given expression value

Expression

count - Count number of the items which match a condition
dateTimeAdd - Add a duration from a DateTime. If no units are supplied, then minutes will be assumed.

dateTimeSub - Substract a duration from a DateTime. If no units are supplied, then minutes will be assumed.

gridSelectCol - Selects the column of a grid
gridSize - Number of rows in a grid.
leadLag - LeadLag is used to schedule a number of units on/off. The 'units' property should be set to a bundle variable that imports the list units the command from the *unit program*. The unit program must have three variables for each unit:

• unit stage number used to determine start order

• unit alarm status as true/false (anything not true is considered false)

• variable used to command the unit; this variable must be set via 'setExternal' block in the unit program

This block's 'numOn' property is used to command all the units on or off.

Each unit in alarm is commanded to off. Any remaining units are commanded on until we reach the desired number on (using unit num ordering).

leadLagStageSelect - LeadLagStageSelect
limit - Limit val between an inclusive min and max
pid - Proportional integral derivative loop
random - Generate a random number between min and max inclusive on every cycle

Language
