[?]: FB Terminals assigment in Step 7 V5.4.

Post by X Rider » Sun Aug 15, 2010 9:58 am

Dear all,
I am a Step 7 V5.4 new user.
I have a question about the terminals name of FB.
For example, FB4, my ladder show only IN1, IN2, IN3... for each terminal. But my friend use V5.3, it shows that what each terminal is.
What I have to do for my V5.4 to show the same thing as V5.3?
Thank you.

You must open the FB and than give names for those IN's in the interface area, pointed just above of the screen. You will
see here the declaration view for IN, OUT, IN_OUT, TEMP, a.s.o.

When you call this FB (let say into an FC) the symbolic of the FB will show the "labeled" IN's, OUT's.

Finally, it is not a matter of version on STEP7, it is only the way you work with it.

Good luck
