Instruction 22 (Module Reconfiguration Requests)
The unit MUST be in remote mode to allow reconfiguration of parameters via the remote control. Setting the unit in
Remote mode can be done either by the front panel or remotely using the instruction 24.
Due to the ability of the DBUH/DLAH/DTLH to accept differing module types into it, the module status request reply
may vary between these different channel types.
