Hello today i tested to connect TIA Portal V18 ans the MS4.

I used the PLC like in the Youtube Tutorial an follow all the steps, so the Digital Signals working fine but the Analog Signals dosn't react no reading or wirting working.

So maybe i make a mistake? The Analog Inputs are not writeable so it will overwrited from outside but the values i type from MS4 into this real 0.0 are not shown in the DB and also the Output i send are not communicate to MS4.

Hi!
Is important the DB length matches between the data configured in the driver and the declared in TIA PORTAL.
In DB properties, make sure you uncheck the Optimized block access, by default it's checked.

Aldo there's an error in some Driver versions, the labels are changed, in the Analog Inputs you must type the DB used for Outputs and vice versa.

The DB's are not optimized the checkmark i remove like in your Tutorial also the PUT/GET Option is turned on. When the lenghs of the DB's dosnt match i getting the message "driver not connected" if they size match it goes to "Driver Connected".

I changed the labels and its still not working the analog I/O's are not usable any other ideas what i can try?

This machine has not Analog I/O, try to use one that uses analog signals.

Oh Okay now it works i thought it will work in any scenario like you tutorial where you use the normal conveyor exercise.

In the Scenario where are analog signals are it works now. THX
