I am using a SHRB for registers between 4082 to 4084. (see pic SHRB)

I am using an interface to sometimes directly set values. So in the PLC program I latch values when someone chooses the position and press a send button(see pic latch).

The Latch comes off when a shift is executed (c4142). But if the coils falls to off even if I shift a '1' in 4082 it will be OFF because it is not forced anymore.

Does anyone have a solution to propose ?
