Most likely it means you have an incorrect I/O space layout.

These are messages from the INIT part of RSTS/E. It assumes that I/O
devices are installed according to the fixed and floating CSR layout
rules. It uses that to identify the devices. Having identified each
by its address, it then tries to verify that it works and what its
vector is by "poking" it. (I don't know if MS ever claimed to have
invented plug & play -- if they did, they are wrong...)

So you have a device whose CSR address says it's DP11 unit number 23,
and when spoken to as if it were a DP11, it doesn't wake up.

Check the floating CSR rules and update your SIMH config...
