Hi guys.

Having some issues with the safety project.

To sum:

1. New TwinCat project;

2. new Safety project;

3. Scan I/O devices;

4. Target System -> physical device selected (EL 1918);

5. Right click on Alias Devices -> Import from I/O configuration -> and nothing to select 🙄 🙄 ...??

Anyone have experienced this kind of situation?

Can you make sure the device exists in the Slot section? 

 

No device :

nodevice

 

Enable Slot: 

enableslot

 

Now the device appears in the IO Tree list: 

IOTree

I can see the device with your tip, but the moment i go to target system and select the EL1918 i can't see it on the I/O tree no more and some configurations change. I don't understand why....

Severity Code Description Project File Line Suppression State
Error For the selected Target System is required a corresponding Alias Device with linking mode "Local".

Anyone knows the meaning of this error?

Hey there. I need to do some updates in here since there were evolution on this.

But for now I want to know if anyone has the idea what this error means?

This error appears when I try to open a PLC project or even from PLC target itself. Already tried to re-install TwinCat but no success
