Good morning.

I need a support in my TIA portal. I have no option to select CPU 1511-1-PN 6ES7511-1AL03-0AB0. I only have one option to select the following CPU 1511-1 PN 6ES7511-1AK02-0AB0.

Now I want to add the following device to my program: 
CPU 1511-1-PN 
6ES7511-1AL03-0AB0

So, give me a suggestion how can I do this?

Hello,

Have a look at the attached file.

-----------------------------------------------------------------------------------------------------

Engineering Software

● STEP 7 TIA Portal configurable/integrated from version:

V20 (FW V4.0) / V18 (FW V3.0) or higher; configurable with older TIA Portal versions as 6ES7511-1AK02-0AB0

------------------------------------------------------------------------------------------------------

@online Tech, Does it mean I have to use TIA V18 with CPU 1511-1 PN 6ES7511-1AK02-0AB0. then it will act like CPU 1511-1-PN 6ES7511-1AL03-0AB0?

Hello,

You can use  "CPU 1511-1 PN   6ES7511-1AK02-0AB0" in the TIA software older that V20  and install "CPU 1511-1-PN   6ES7511-1AL03-0AB0" in the real PLC rack without any problem.
