BATCH CONTROL −
Part 1: Models and terminology
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61512-1 has been prepared by subcommittee 65A: System aspects,
of IEC technical committee 65: Industrial-process measurement and control.
IEC 61512 consists of the following parts, under the general title Batch control:
– Part 1: Models and terminology;
– Part 2: Data structures and guidelines for languages.
The text of this standard is based on the following documents:
FDIS Report on voting
65A/217/FDIS 65A/238/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Annex A forms an integral part of this standard.
Annex B is for information only.

INTRODUCTION
The models and terminology defined in this part of IEC 61512
– emphasize good practices for the design and operation of batch manufacturing plants;
– can be used to improve control of batch manufacturing plants; and
– can be applied regardless of the degree of automation.
Specifically, this standard provides a standard terminology and a consistent set of concepts
and models for batch manufacturing plants and batch control that will improve communications
between all parties involved; and that will
– reduce the user's time to reach full production levels for new products;
– enable vendors to supply appropriate tools for implementing batch control;
– enable users to better identify their needs;
– make recipe development straightforward enough to be accomplished without the
services of a control systems engineer;
– reduce the cost of automating batch processes; and
– reduce life-cycle engineering efforts.
It is not the intent of this standard to
– suggest that there is only one way to implement or apply batch control;
– force users to abandon their current way of dealing with their batch processes; or
– restrict development in the area of batch control.
The models presented in this standard are presumed to be complete as indicated. However,
they may be collapsed and expanded as described below. The unit and the control module
levels may not be omitted from the physical model. The master recipe and the control recipe
may not be omitted from the recipe-type model. Specific rules for collapsing and expanding
these models are not covered in this standard.
– Collapsing: elements in the models may be omitted as long as the model remains
consistent, and the functions of the element removed are taken into account.
– Expanding: elements may be added to the modules. When they are added between
related elements, the integrity of the original relationship should be maintained.
