Tia Portal - Bit to byte array element via put command

Hi,

I am trying to send a true bit (1) to the 1st bit of the 8th byte element of an array at a remote (partner) PLC through the Put FB. In the remote PLC, the array is stored in the [DB200] data block. Does anyone know what I should type in the ADDR1 field?

I always get error messages as in the attached screenshot

Thank you
