225 COMMANDS
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.
Bit0 Gross/Net
Bit1 Print
Bit2 Zero
Bit3 PB Tare
Bit4 KB Tare, requires float point value be sent in bytes 4, 5, 6, and 7
Bit5-6 not defined
Bit7 This bit is the error bit from the 225 when a command fails.
