Table of commands for ASM 854
The assignment is made in UDT 20 using the "Command" variable (see Section "Command
parameter settings").

The command table is valid for the FB 45. No commands are transferred to the ASM when
fixed-code MDSs are processed with the process image.
Special features of the fixed-code MDS (MOBY_mode = A)
When in this mode, the ASM
automatically reads each new MDS as it arrives. The user does
not need to start a command.
The user issues the read command using UDT 20. repeat_command and command_start
must then be issued simultaneously to start the command and fetch the data.
