Property projector and Property sensor not working

Hello

 

I have created two properties,

1. Anti-grease 

2. Base coat

 

Now i created a Property Projector  - 

Assigned Anti-grease property to it.

Assigned Name & car part to detect.

 

I placed this property projector so that it's beam should fall on car part completely.

 

And Now i created a Property sensor  -

Assigned Anti-grease property to it.

Assigned Name & car part to detect.

 

I placed this Property sensor so that it's beam should fall on car part completely.

 

I added this Property Projector and Property sensor both in Simulation Panel,

 

Now when i start Line simulation - Start in Sequence editor,

 

The generated car part appearance is passing through both property projector and Property sensor

But both are not working in Simulation panel where input and outputs both should turn to 1 from 0.

 

Please note i have activated both sensors.

 

Kindly provide any solution for this issue.

Hi,

 

have you added the sensor signal to an LB or used it somewhere in the Modules Viewer?

The sensor signals must be used.

 

Best regards

Re: Property projector and Property sensor not working

I have created a photo electric sensor just beside Property Projector,

 

Now i linked this photo electric sensor to Property Projector in Module viewer,

ie - Result signal - Property Projector

      Expression     - photo electric sensor

 

Now The Property Projector is working - turning to 1 from 0 - signal status in simulation panel,

 

But Property Sensor is not working - Its not detecting the Property projected  - not tuns to 1 from 0

Hi,

 

See my simple test study attached.

I created it with PS15.0.

 

You need to use the property_projector and the property_sensor in combination.

With the properties you decide only which names work signals will have.

 

In Simu Panel you need to force a value for your projector. With the sensor you can check the value on the part.

 

Best regards

In Process Simualte in general signals which are not used anywhere by the simulation (meaning assigned to an LB, a Module, a PLC) are ignored and their value is not calculated. This is done due to performance considertations as sometimes numerous signals are imported into a study which are completely unseud but are updated every cycle uselessly. 

Sounds like that's what you are experiencing. The Property Projector started working once it was hooked to something (also true for your Light Sensor by the way) but your Property Sensor is not connected and thus still inactive.

 

This is something Siemens plans to improve in the future in order to make simple testing such as this easier to achieve.

Re: Property projector and Property sensor not working

Dear Patrick

Thank you very much for the study.

Re: Property projector and Property sensor not working

Now in my PS 13.1,

 

Property sensor and Property Projector both are working.

 

I just used Property sensor signal to trigger some other process, means

In Module viewer

Resultant signal  -  Pick the car part

Expression            -  Property sensor signal

 

Property sensor works only when you use it to trigger another process.

Dear Gal_Snir

Thank you very much for your valuable time,
Property sensor started working when i used it to trigger some other action.
