All tasks performed by the 1309 are controlled over the IEEE/IEC inter-
face from a System Controller; there is no other control possibility. This
chapter deals with the control of the 1309 from the user’s point of
view; for details of the IEEE/IEC interface specifications, refer to
Chap-
ter 4
of this manual.
Sections 3.1
and
3.2
deal with switching-on and the general principles
of controlling the 1309.
Sections 3.3
to
3.7
deal with the specific com-
mands and requests, known as interface jobs, which set-up and control
the 1309. 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 1309 can be switched on using the AC Mains switch on the back-
plate. After switching-on, the 1309 is set as follows:
The sampling-valves closed.
Internal three-way valve set to Waste Air Outlet.
3.2 General Principles of Controlling the 1309
The 1309’s functions are controlled over the IEEE/IEC interface using a
range 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 1309. Further details about the
IEEE/IEC interface of the 1309 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 1309. Each constituent part of the interface
job is explained below.
