2021.1.1208.2 Logic Simulator

1 Overview

3 Feature overview

Overview

The Logic Simulator manages all child components connection to the gateway adapters.

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 (create link to adapters) and a collection of Logic Components (create link to logic component).

The configuration result is saved as a XML policy file.

In this article you find information on how to setup this manager to establish a connection. Specific adapter configurations can be found here (create link to adapters)

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 (create link) for more information about specific adapters.

Configuration Settings are Twincat ADS specific. If using other external gateways, ignore this section

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 lifecyle management if supported by the selected adapter.
Stream Client State	Returns the state of the client.

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

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
Sim Name Formatting	Naming used within Prespective to identify the IO 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.

Update screenshot

A policy file has all the necessary information to connect to the external source. 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.

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.
