DL8000 Preset Instruction Manual
Revised February-2016
Communications Protocols
D-13
The TAS issues a Stop Batch command [0x0F] when the batch is in
progress and not stopped (bits 10 and 21 in [63,0,119]).
An alarm with a severity greater than info is raised (for example, the
Current Alarm Type [63,0,64] has a value more than 1).
A batch that is stopped because of these conditions
may
be restarted.
The DL8000 sets a flag (bit 21 in [63,0,119]) to indicate that the batch
has stopped and can be restarted.
A batch
ends
when either of the following conditions occurs -
The preset volume of all the components in the blend or recipe has
been delivered.
The TAS issues an End Batch command (hex 0x0D) when batch is
in progress and stopped (bits 10 and 21 in [63,0,119]).
Batch has been stopped when the batch remaining quantity [63,0,3]
is less than minimum preset quantity [63,0,27].
A batch that has ended
cannot
be restarted. The DL8000 sets a Batch
Ended flag (bit 13 in [63,0,119]) to indicate that the batch has ended and
is not restartable. The authorization of a new batch or the issue of a
Clear Status command clears the batch ended flag.
In the DanLoad 6000 protocol, the TAS uses the Batch Data by
Component command (hex 0x10) to obtain batch data (batch volumes,
component temperatures, batch sequence number, transaction sequence
number, and so on) for a batch that has ended.
D.2.4 End of Transaction
In
automatic
operating mode, any of the following conditions can end a
transaction:
The TAS issues an End Transaction command (hex 0x07) when the
transaction is authorized and there is no batch in progress (bits 18
and 10 in [63,0,119]).
The operating mode [63,0,36] is changed and transaction was
authorized.
The DL8000 was powered and a transaction in progress when the
DL8000 was powered down.
In
manual
operating mode, you can end a transaction by pressing
Stop
on the DL8000, provided no batch is in progress.
In
automatic
mode, an operator can press
Stop
to request the TAS to
end the transaction. The DL8000 then sets the Transaction End
Requested flag (bit 19 in [63,0,119]). The TAS reviews this flag and
issues an End Transaction command (hex 0x07). When the DL8000
receives an End Transaction command, it sets a flag (bit 12 in
[63,0,119]) to indicate that the transaction has ended. The authorization
of a new transaction or the issue of a Clear Status command clears the
Transaction Ended flag.
