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) of batch group 1 to “ABCD”
"**" denotes any value.

Write the entire character string using one command.
In the above example, registers 410003 to 410005 must be written using one
command.
A zero is read when you read a write-only register.
Lot number
• Access the registers two registers at a time.
• You can only access from the first register.
• On models without the multi batch function (/BT2 option) or on models
with the multi batch function (/BT2 option) but with the multi batch
function disabled, if you access a lot number of a batch group, an error
occurs.
Batch number
• You can only access from the first register.
• On models without the multi batch function (/BT2 option) or on models
with the multi batch function (/BT2 option) but with the multi batch
function disabled, if you access a batch number of a batch group, an
error occurs.
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. On models without
the multi batch function, you only have to write to registers 410601 and
410602 instead.
On models without the multi batch function, 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.
On models without the multi batch function, 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.

Computation reset
On models without the multi batch function (/BT2 option) or on models
with the multi batch function (/BT2 option) but with the multi batch function
disabled, if you access computation reset of a batch group, an error occurs.
