15.4 Programmable Logical Controller (PLC)
It must be responsible for the plant operation proper. All process control function of variables
and commands for the equipment must be executed through  it,  including, while the
operation is running, via the local control panels. Only the commands installed on the
emergency desks and panels will not pass through the PLC.
Data inputs and outputs and commands (RIO) may be installed near the monitoring and
control points, as long as they are sufficiently protected. The correction of these RIO's with
the CPU's must be made via fiber optic with different redundancy and routes.
All the plant's units and subsystems must be connected to the PLC via network and those
different from the installation standard must be connected via input and output modules.
VSB will inform the supplier the name of the PLC manufacturer to be used. The model will
be jointly determined in function of the plant's requirements and the standardization in view
of future facilities. The use of PLC's from different suppliers in one plant will not be allowed,
except if there is previous authorization by VSB.
The entire philosophy for developing and identification (tags), arrangement, comments,
memory map, etc. will be discussed between the developer and the VSB team at an
opportune time. Therefore VSB must present a specific standard guideline or validate the
developer's presentation or, still, develop it together.
The programming language must be Ladder Logic and/or the Function Block Diagram.
Other languages will be allowed only, if unavoidable, within customized operational blocks
for specific functions.

TECHNICAL SPECIFICATION
ELECTRICAL, AUTOMATION AND INSTRUMENTATION SYSTEM -SPECIFICATION AND INSTALLATION GUIDELINE  VS1
15.5       General concepts:
15.5.1 The architecture, as well as the electrical supply philosophy for all equipment and elements
of the automation system, must previously be approved by VSB already during the basic
project stage.
15.5.2 The number of PLC's must be determined by considering not only the "Total Cycle Time" but
also the interdependence of the plant's areas, thus making it possible that, even if some
CPU is out of operation, other parts of the plant, whose operation can continue, will not be
affected.
15.5.3 The CPU's of the PLC's must have at least 30% spare space in the program's memory,
considered after commissioning.
15.5.4 All inputs and outputs (l/O's) of the same functionality should not be concentrated in the
same module so that, if this module fails, the control of all similar equipment will not be lost.
15.5.5 Redundant digital or analog signals must be connected to different PLC modules.
15.5.6 Independent protection devices for each PLC module should be foreseen.
15.5.7 Galvanic insulation  must be installed if the PLC's analog modules do not have any
protection against atmospheric surges.
15.5.8 All different I/O modules of the PLC must have at least 15% of prewired spares.
15.5.9 All PLC backplanes must have at least 10% free slots for future expansions.
15.5.10 The following standards, as reference, are to be complied with:
ISA- 5.1 Instrumentation Symbols and Identification
ISA - 5.2 Binary Logic Diagrams for Process Operations
ISA - 5.3 Graphic Symbols for Distributed Control/Shared Display Instrumentation, Logic
and Computer Systems
ISA - 5.4 Instrument Loop Diagrams
ISA - 5.5 Graphic Symbols for Process Displays

Elements, and Control Valves

15.5.11 The PLC and the SCADA must provide a well-structured base of comments with the
purpose to facilitate understanding and agility when performing tasks. These comments
must be in the Portuguese language and, should this not be possible, VSB must previously
authorize that in such cases the comments will be in English.
15.5.12 VSB must receive all source codes related to the developed programs, as well as all used
software licenses. The licenses must provide freedom to install a sufficient number of
machines for optimum performance of development and maintenance. This matter must be
clarified prior to the Detailed Project.
15.5.13 The supplier must present in writing a Contingency Plan for the case of failure in the
automation system related to critical equipment (e.g. reheating furnaces).
16 INSTRUMENTATION
The instrumentation must perform all necessary measurement and control functions for the plant's perfect functioning. The control philosophy must always be

agreed between the plant's supplier and the VSB team, benefiting at maximum from the know-how accumulated by the parties. The list of sub-suppliers may

contain only first class manufacturers and the models to be applied must be previously approved by the VSB team. Knowledge of standard VS-E-011-2 is

mandatory for the project's development and the specification of the instrumentation elements.
16.1       General conditions:
16.1.1 All transmitters must have a local indication of the measured variable.
16.1.2 The supply of the main instruments must be made via UPS. Attention must always be paid
to the installation's electromagnetic compatibility as a whole.
16.1.3 Redundant 24 Vdc stabilized sources for supplying the transmitter must be foreseen. Each
source must be supplied by different circuits.
16.1.4 Transmitters and other intelligent type elements must be applied in the main functions and
interconnected via PROFIBUS PA network.
