Overview

A Logic Simulator enables Prespective to connect to external logic controllers like PLCs. A Simulator object is a container that manages the connection to an adapter and a collection of Logic Components.

The configuration result is saved as a XML policy file for easy exchange and adaptation.

In this article you find information on how to setup this manager to establish a connection. Specific adapter configurations can be found at each adapter page.

Where to find

The Logic Simulator can be found under Logic.

This will create a PreLogicSimulator in the Hierarchy.

Feature overview

Gateway Settings are adapter-specific, please see the Adapter page for more information about specific adapters.

 

Simulation Settings

 

Simulation Settings

 

Simulator Name

Name used for to identify the simulator.

Start in Playmode

Automatically start the simulator when entering playmode.

Stream Connection

Shows the current state of the connection to the external source.

Content Lifecycle State

Returns the current status of the lifecycle management if supported by the selected adapter.

Stream Client State

Returns the state of the simulator.

Content life cycle management is not (yet) supported for most adapters

 

Logic Components

 

Logic Components

 

Logic Component (0)

Shows a list of all child components of this simulator

Logic Components automatically updates when a logic component is attached to the simulator

 

 

Signal Naming Rule Overrides

The naming rule override field can be used to apply the set rules to all connected child components. Increment the size generates a new rule.

Signal Naming Rule Overrides

The naming rule override field can be used to apply the set rules to all connected child components. Increment the size generates a new rule.

Signal Naming rules (#1)

 

Size

Amount of signal naming rules

Rule: $ALL

 

Target

$ALL : this rule applies to all signals within this instance, overruled by all below options

$INPUT : this rule applies to all PLC Input signals within this instance, overruled only by a custom rule

$OUTPUT : this rule applies to all PLC Output signals within this instance, overruled only by a custom rule

$VARIABLE : this rule applies to all PLC Variable signals within this instance, overruled only by a custom rule

[CUSTOM] : applies only to the signal with the name [CUSTOM], overrides all other rules. This can be used to override a specific IO for example

Sim Name Formatting

Internal Naming used to identify the IO instance.

Variables that can be used to here:

{{SIM_ROOTPATH}} : unity path to the active simulator root object

{{SIM_NAME}} : name of the simulator used in unity

{{COMP_SIMPATH}} : Unity path to the prelogic component

{{COMP_NAME}} : name of the prelogic component

{{IO_NAME}} : Name of the IO defined in the signal definition

{{INST_NAME}} : variable that can be modified by the instance naming rule

PLC Address Formatting

Naming used within on the PLC to identify the IO

The same variables can be used as in the sim name

Sim Path Separator

Separator character used in the the Sim Name Formatting

“_” by default

PLC Path Separator

Sepearator character used in the the PLC Address Formatting

“.” by default

Apply Signal Naming Rule Overrides

Overrides the sginal naming rules on all connected child components

 

Instance Naming Rule Overrides

One can set the implicit naming rule override in this field per simulation component type.

Instance Naming Rule Overrides

One can set the implicit naming rule override in this field per simulation component type.

Instance Naming rule (#0)

 

Add new rule

Adds a new rule field

X

Remove this rule

Delete All

Removes all rules

Target Component

The component script file on which the naming rule applies

Naming Rule

The actual implicit naming rule that should be applied

Apply Instance Naming Rule Overrides

Applies the set rule to all connected child components with attached TargetScript.

Policy Settings

 

Policy Settings

 

Policy Directory

Path relative to the assets folder for storing the policy file

Policy Filename

Name for the saved XML file

Policy Export Settings

 

Export Type Policy

Exports the type definition for the specific adapter.

On by default.

Legacy Commenting

When on it does not export a Description element.

Off by default.

Comment to Split Signals By Component

Split the IO definition in inputs, output and variable blocks.

On by default

Name And Address On Single Line

Puts the name and address element on a single line,.

On by default

Allow Initial Value

Adds the initValue field in the export.

On by default

Allow Priority

Adds the priority element on the export.

On by default

Export Policy to XML

Exports the file to the given XMLPath provided by the Adapter settings.

Open Policy File

Opens the exported file with the default xml program defined in windows if the file exists.

 

Policy File

A policy file has all the necessary information to connect to the external source. Everything in the XML will be loaded when entering playmode or starting the Unity build. Everything in the policy file will update the simulator. Make sure they are synchronized. Reexport when unsure.

The dataset consist of two parts:

Active Controller Definition and Type Definitions

Active controller definition consist of two parts. The adapter specific connection parameters and the IO definition.
