CMD0 and CMD1 are combined to make the command word. Command words are
broken into command bits for PLC ease of programming. To invoke a command, set the
bit to one. The PLC should continue to send a command until the command is returned
by the indicator. If the indicator cannot perform a command, the returned command will
include bit 7. The scale number is encoded as a four bit binary number, 1 through the
number of scales available. NOTE: ALL COMMAND BITS SHOULD BE RELEASED
AFTER THEY ARE PROCESSED BY THE INDICATOR.
