How to Use
Item Description
Data type STRnn Registers in which ASCII codes are entered starting with the specified
register. It is terminated with a NULL character (\0).
The number of characters that can be entered that includes the NULL
character is indicated in the nn section.
Example of setting the batch number (STR36 type) to “ABCD”
“**” denotes any value.
Register Value to Write Hexadecimal Notation
407835 'A''B' (4142H)
407836 'C''D' (4344H)
407837 '¥0'* (00**H)
407838 to 407851 ** (****H)
Write the entire character string using one command.
In the above example, registers 410003 to 410005 must be written using one
command.
If you read a write-only register (one whose access is only “W”), zero is
always read.
Lot number • Access the registers two registers at a time.
• You can only access from the first register.
Batch number • You can only access from the first register.
Message • You can only write from the first register.
• A message is written using one command. In other words, write to
registers 410601 to 410603 using one command.
The message write destination can be omitted (write only to 410601). If you
omit it, the operation is the same as when all groups are specified.
Free message • You can only write from the first register.
• A free message is written using one command.
If you omit the free message section, an all-space message is written.
The message write destination and subsequent registers can be omitted (write
only to 410611). If you omit them, an all-space message is written to every
group.
Example: To write the free message “ABCD” to all display groups in batch
group number 4 using message number 10, write the values in the
following table using one command. “**” denotes any value.
Register Value to Write Hexadecimal Notation
410611 10 (000AH)
410612 0 (0000H)
410613 1 (0001H)
410614 'A''B' (4142H)
410615 'C''D' (4344H)
410616 '¥0'* (00**H)
Simultaneous access • Batch numbers and lot numbers can be written using one command for
each batch.
Example : You can write to registers 407833 to 407851 using one
command.
• When reading, you can access the following registers simultaneously.
• Internal switches 1 to 30
