Hello,

 We have PCS7 in the plant and we added KP8F panel into it. I used KP_PP block (FB1513), configured addresses and it's not working.

When i press the key, it changes the bit to 1, but for LED's there is no way how to light it up. Q_Lamp01 output is always 16#00 and never changes independend on inputs for LED's.

If I change it thru VAT table directly, LED's are working correctly.

Is there some new library or why the block isn't working? Thank you in advance.

Solved, 

there was conflict in output without any message by Siemens...
