4.3.10 BATCH INITIATION (Cont.)
NON OPERATOR INITIATION
Batch start/stop can be initiated by job, by counter or via MODBUS/TCP
JOB INITIATION
As described in section 4.7.8 , a job can be set up to initiate a batch whenever the job source becomes
active. If ‘Scope’ is set to ‘Group’ a specifi c group can be selected (default = Group 1) and the job will act
only on the batch associated with this group. Batch ‘Start’ jobs automatically start the batch using the
entries made during the ‘
Store ’ function, described above. ‘Display Batch Dialog’ jobs allow the user to
enter the fi eld values manually, before the job starts.
COUNTER INITIATION
If Batch Number is selected as ‘Use Counter’, then a new batch will automatically be started whenever the
selected counter changes value (increment, decrement or preset). The new value of the counter is used
as the value associated with Field 1.
For the other fi elds to have values printed on the chart, these must have been entered as described
above for Operator initiation, then the ‘Store’ button touched.
The ‘On new clear’ setting is ignored, the stored values being used each new batch.
Batch start messages are of the form:
DD/MM/YY HH:MM:SS Batch start (Automatic)
Batch recording cannot be stopped by Counter action.
MODBUS INITIATION
In order to initiate batch recording via MODBUS/TCP, a Batch Start fl ag has to be set (value = 0001). For
Scope = Group, the fl ag for the specifi ed group must be set. For Scope = Instrument any group’s Batch
Start fl ag may be used.
The address of the fl ag for group 1 is decimal 42364; the address for group N is {42364 + 629(N-1)}
For further details of the Modbus TCP option see section 8 .
If Batch mode = Start/Stop, batches can also be stopped via MODBUS. The address for group 1 is 42365;
the address for group N is {42364 + 629(N-1)}. Again the value must be set to 0001.
Modbus start messages are of the form:
DD/MM/YY HH:MM:SS Batch start (Modbus)
Stop messages are similar.
EVENT SOURCES
As described in section 4.3.6 , ‘Batch Start’, ‘Batch Running’ and ‘Batch Stop’ can be selected as event
sources. If ‘Scope’ = ‘Group’ in Confi guration (described above), then the user can select which group’s
batch is to be used as the event source.
