How to read Digital Inputs from KL 1808 with Beckhoff BK9103

Hallo,

am currently working with Beckhoff BK 9103 Bus coupler along with PLC S7-1500 (1516-3 PN/DP). As you can see in the images below, KL 1808 is connected to a SIRIUS Contactor. The Input 1, 2, 3 and 5 are NO, whereas the Input 4 and 6 are NC. The Ouput 1 from the KL2828 is connected to the contactor and supplies 24V. When the Output 1 is turned on, the contactor is ON and the LEDS 1, 2, 3 and 5 in KL 1808 are ON as well. When the Output is turned off, LEDs 4 and 6 are ON, as they are normally closed. The problem I'm facing is when I am not able to read the Digital Inputs (KL1808) when they are ON in Tia Portal, even though I am able to control the Digital Output (KL2828).

Closed cause question posted twice.
