9.1.6 Batching Control Commands
The commands listed below provide batching control
through the serial port.
BATSTART
If the BATRUN digital input is active (low) or
not assigned, the BATSTART command can be
used to start the batch program.
BATSTOP
Stops the batch program and turns off all
associated digital outputs.
BATPAUSE
Stops the batch program at the current step. All
digital outputs set on by the current step (except
for those set by concur setpoints) are set off. The
BATSTRT DIGIN, BATSTART serial command,
Batch Start softkey, or the StartBatch function in
an iRite program can be used to restart the batch
program at the current step.
BATRESET
Stops the program and resets the batch program
to the Þrst batch step. Run the BATRESET
command after making changes to the batch
conÞguration.
9.1.7 Database Commands
The commands listed in Table 9-12 can be used to
create and maintain databases in the
920i . Except for
t h e D B . D E L A L L c o m m a n d , a l l o f t h e d a t a b a s e
commands require an extension to identify the number
of the database within the memory card and the slot
number of the memory card.
DB.ALIAS
The DB.ALIAS command is used to get or set the alias
used by iRite programs to reference the speciÞed
database. Each database alias must be unique among
all databases and adhere to the following rules: 8
character maximum; must begin with an alpha
character or an underscore; can only contain AÐZ, aРz,
0Р9, or an underscore (_).
Example. The following command assigns an alias of
TRUCKS_2 to the Þrst database on the memory card
installed in slot 2:
DB.ALIAS.1#2=TRUCKS_2<CR>
Sending the DB.ALIAS command alone, without
assigned data, returns the current database alias.
DB.CLEAR
To clear the contents of a database, send the following
command:
DB.CLEAR.n#x<CR>
Where:
n is the database number within the memory card
x is the slot number of the memory card (0 is the
onboard memory)
The 920i responds with OK<CR> if the command is
successful, ??<CR> if unsuccessful.
DB.DATA
The DB.DATA command can be used to send data to or
retrieve data from the 920i .
Data can be sent to the indicator using the following
command:
DB.DATA.n#x = data{ | }<CR>
Where:
n is the database number within the memory card
x is the slot number of the memory card (0 is the
onboard memory)
data represents a single cell of a row of data
{ | } is a pipe character (ASCII 124), used to
delimit cell data. If the data being sent is not the
last cell of the row, append the pipe character to
the data to indicate that more data is coming for
that particular row. If the data being sent is the last
cell of the row, do not append the pipe character.
If the command is accepted, the 920i responds with
OK<CR> ; if not, it responds with ??<CR>.
XE Query system error conditions nnnnn
