Emerson DL8000 - Steps for Authorizing a Batch

DL8000 Preset Instruction Manual
Revised February-2016 Communications Protocols D-11
Authorizing the Transaction
The TAS “authorizes” a transaction using the Authorize Transaction
command (hex 0x06). This command:
 Sets the recipe, additives, and data items.
Note: Write the recipe, additive, and data items before you issue
the Authorize Transaction command.
 Sets the Transaction Authorized flag (bit 18 in [63,0,119]).
 Clears the Additive Selected and Recipe Selected flags (bits 5 and 4
in [63,0,119]).
 Displays (if it is not already) the loading screen.
 Increments the transaction sequence number [63,0,124], which rolls
from 9999 to 0 to indicate the prospective sequence number of the
transaction (if it starts).
Note: The transaction does not actually start (“in progress”) until the
first batch starts. The DL8000 sets a Transaction in Progress flag
(bit 9 in [63,0,119]) to indicate that a transaction is actually in
progress.
D.2.2 Steps for Authorizing a Batch
The following sections explain the steps for authorizing a new batch for
loading the required preset.
Preset Volume for Batch
The TAS can command the DL8000 to prompt the operator for a preset
volume using the Prompt Preset Volume command (hex 0x08). When
the TAS issues this command, the DL8000 displays a preset selection
screen. This command can optionally send a “suggested preset volume”
[63,0,185].
The operator can either press Enter to accept the displayed preset or
press Alt + Backspace to change the preset volume. The operator must
enter the preset volume within the timeout time [63,0,171]; otherwise
the DL8000 aborts the operation and sets an Operation Timed Out flag
(bit 3 in [63,0,119]).
Note: If you set the timeout to zero then a timeout does not occur.
Once the operator enters a preset value, the system sets the preset
entered flag (bit 6 in [63,0,119]). The Preset Volume Entered flag is
subsequently cleared by another Prompt Preset Volume command or a
Clear Status (hex 0x13) command.
In the DanLoad 6000 protocol, the TAS can read the entered preset
volume [63,0,39] using a Request Preset Volume command (hex 0x09).
