The command is valid only when the UM setting is ladder only.
The command can't be executed if the UM area is read-protected.
Data is read from the beginning of the ladder area to the maximum limit of the
program area. (For example, $A06C0 through $A7FBF when the UM size is 16K
words and none of the UM area is allocated to expansion DM or I/O comments.)
The beginning read address and the length of the response depend on the UM
area settings (such as the amount of memory allocated to expansion DM).
The response's first frame can contain up to 30 words of program data. The se-
cond and later frames can contain up to 31 words each.
The INITIALIZE and ABORT commands can be sent instead of the delimiter for
multiple responses for this command. If other commands are sent, they will be
treated the same as delimiters.
