All tasks performed by the 1303 are controlled over the IEEE/IEC inter-
face from a computer; there is no other control possibility. This chapter
deals with the control of the 1303 from the user’s point of view; for de-
tails of the IEEE/IEC interface specifications, refer to
Chapter 4
of this
manual.
Sections 3.1
and
3.2
deal with switching-on and the general principles
of controlling the 1303.
Sections 3.2
to
3.8
deal with the specific com-
mands and requests, known as interface jobs, which set-up and control
the 1303. Each interface job is dealt with by giving an example which
states the effect of the job. For quick reference, an overview of all in-
terface jobs is given in
section 4.2
of this manual.
3.1 Switching-On
The 1303 can be switched on using the AC Mains switch on the back-
plate. After switching-on, the 1303 is set as follows:
All dosing- and sampling-valves closed;
Internal three-way valve set to Waste Air Outlet;
Both pumps stopped;
Main dosing valve closed.
3.2 General Principles of Controlling the 1303
The 1303’s functions are controlled over the IEEE/IEC interface using a
repertoire of commands and data requests, each of which is specific to
a particular function or item of data. These commands and requests are
known as interface jobs. This section describes the structure of the in-
terface jobs used to control the 1303. Further details about the
IEEE/IEC interface of the 1303 are given in
Chapter 4
of this manual.
3.2.1
Syntax for Interface Jobs
Fig.3.1
shows a diagram representing a single interface job, sent from
the system controller to the 1303. Each constituent part of the interface
job is explained below.
