Job Headers
The job header specifies the function you want the 1303 to perform. It
consists of one or more words. The ASCII underline character “_” is
used to separate individual words in the job header. For example:
OPEN_SAMPLING_VALVE
A hyphen “-“ or a full stop”.” can also be used to separate words in the
job header.
The words making up the job header do not need to be sent in full to
the 1303; they can be shortened to a code-form, for example:
OP_SA_VALVE
O_S_V
The minimum code for each job header is usually the first character of
each word in the job header. This is written in bold characters in the list
of interface jobs given in section 4.2 of this manual. The 1303 accepts
job headers in both upper- and lower-case characters.
The Data Field
The data field contains further information specific to the interface job
defined by the job header. The data field is separated from the job
header by a space character (“SP”), or a comma “,”. In the following
examples, the separator will always be the space character, repre-
sented by the symbol “ ”. The data field will normally contain a numeri-
cal value. For example:
OPEN_SAMPLING_VALVE 2
Some jobs may require more than one item of data. In this case, the
data is given item by item, separated by commas. For example:
