Functional blocks of the workflow scheme:

• "Start" block
• "Finish" block
• "Robot" block
• "Screen Form" block
• "And" boolean gateway
• "Or" boolean gateway
• "Workflow" block
• "Note" block

"Start" block

The "Start" block is the starting point of the workflow.

...

The panel with the properties of the workflow parameters opens to the right of the workspace of the Workflow Designer and looks as follows: 

Workflow parameter properties panel

Each workflow parameter has its own panel, which contains:

...

Example of setting a parameter: 

Types of workflow parameters

String

You can specify the value of a parameter of this type using letters of any alphabet, numbers and symbols.

...

A table is specified as a JSON object. For example, the value of a parameter with a 3x3 table type with string values will look like:

All values in the table must be of the same type: all blocks must be either strings, or boolean or numbers.

Adding a workflow parameter

Using the "Add Parameter +" button, multiple workflow parameters can be added to the Start block. Each new parameter will be numbered in order: 

Deleting a workflow parameter

A workflow parameter can be deleted from the parameter list using the "Trash" icon located in the upper right corner on the property bar of the specific parameter to be deleted.

"Finish" block

The "Finish" block is intended for setting the parameters of the workflow result. Any input and/or input parameters of a workflow/task/SF/subprocess can be used as result parameters.

...

For the workflow, the scheme of which is shown in the figure below, the robot output parameter " Adding 2 numbers" is chosen as the final result of the workflow, which adds 2 numbers: the degree of the first workflow parameter and the area of a circle with radius equal to the second workflow parameter. 

"Robot" block

The "Robot" block performs a robotic task. The block has 3 common properties:

1. Robot name (filled in automatically after selecting the robot).
2. Robot description (filled in automatically after selecting the robot).
3. Block color (filled in by the workflow designer).
4. Special launch:
   • Host (filled in by the workflow designer after the robot is selected)
   • Account (filled in by the workflow designer after robot is selected)
5. Input parameters (filled in by the workflow designer after robot is selected).

Selecting a robot

To select a robot as the executor of a task, you must click on the "Select robot" button. 

...

When you click on the "Select robot" button, a list of ready-made robots appears, in which you must select the one that will perform the task. The robot is selected using the left mouse button. As an example, we have selected the robot "Exponentiation", which, as the name implies, increases a number to a degree: 

General properties

After selecting a robot, the Robot block's properties panel will display:

...

The rest of the properties must be filled in by the workflow designer.

Special launch

In a special launch, the designer is given the opportunity to select:

1. The host on which the robot will be loaded.
2. The account under which it will be executed.

Input parameters

Fields for robot input parameters appear automatically based on the robot's internal specification. The designer only has to bind them either to workflow parameters or to parameters of previous tasks.

...

This completes the work with the "Robot" block.

"Screen form" block

The "Screen form" block performs a user task.

...

1. Task name (filled in automatically after selecting an SF).
2. Description (filled in automatically after selecting an SF).
3. Block color (filled in by the workflow designer).
4. Responsible - selected by the designer from the list, by default the executor is "Initiator".

SF selection

To select an SF for a user task you should click on the "Select a screen form" button. 

...

are filled in by the workflow designer. 

Selecting the responsible

The responsible is an individual, an employee of the company and at the same time a user with the role "Task Executor", who will work with the SF.

...

The user or user group is also searched by the first entered characters 

Block Color

Block color is a common optional property of any block. It is filled in the same way as for all other blocks.  

Priority

The workflow designer can set the priority of a task, which should be used by its executor when selecting the next task, if there are several user tasks in progress at the same time.

...

A task may have the following priorities:

1. High
2. Medium
3. Low 

Deadline

The deadline is set in days, hours and minutes and is counted from the moment the task has a specific executor. If a task's deadline expires, the executor, workflow owner and administrator will receive a notification that the task has expired, if they are all subscribed to this type of notification. Upon receiving such a notification, the workflow owner should find out the reason for the delay in execution and take the necessary measures to eliminate them as soon as possible.

Input parameters

The fields with input parameters are created automatically on the basis of the internal specification of the SF. The workflow designer only has to set the values of these parameters.

...

In this case, the task executor, while working with SF #1, will see 2 fields in it with the values of workflow parameters that were set either by default or at launch.

"And" boolean gateway

The "AND" boolean gateway is designed to parallelize the workflow by branches. The number of parallel branches is unlimited and they must converge in one (robotic or user) task.

...

• Block name
• Block sizes
• Color (to be filled in by the workflow designer)
• Description 

"Or" boolean gateway

The "Or" boolean gateway is intended for branching a workflow by a condition. The condition can be a single condition or there can be several conditions.
The condition is set only after creating a connector with the subsequent blocks of the scheme. The number of conditions of a block is equal to the number of connectors (workflow branches) coming from the block.

Condition Constructor

In the scheme shown below, the "Or" block has two outgoing guides to two "Robot" blocks: 

...

Conditions can be edited at any time by clicking on the "Gear" button. To delete a condition, click the cross icon on the conditions panel or the "Trash" icon in the condition builder.

"Workflow" block

The "Workflow" block is designed to use another workflow that has already been published to execute a business task. The configuration of this block is very similar to the work with the "Robot" block.

...

• Workflow name (filled in automatically after selecting a subprocess)
• Workflow description (filled in automatically after selecting a subprocess)
• Block color (to be filled in by the workflow designer)
• Input parameters (to be filled in by the workflow designer after selecting the robot)

Selecting a workflow

To select a robot as the executor of the task, click on the "Select Robot" button. 

...

We used the search bar to select the workflow.

General properties

Once a workflow is selected, the properties panel of the Workflow block will display:

...

The other properties must be filled in by the workflow designer.

Input parameters

Fields for subprocess input parameters appear automatically based on the internal specification of the subprocess. The designer only has to link them either to the main workflow parameters or to the parameters of previous tasks.

...

This completes the work with the "Workflow" block.

"Note" block

The "Note" block does not affect the workflow and is intended for the workflow designer - present or future - who will take it for revision or reworking.
