Essential tools of the standard engineering software and their
functions:
SIMATIC Logon
SIMATIC Logon is a user administration and access control func-
tion integrated in the engineering system. Together with the de-
tailed recording facilities provided by the change log, SIMATIC
Logon offers plant owners exceptional system support when ver-
ifying changes.
Using SIMATIC Logon, the administrator can assign specific ac-
cess privileges to groups of users, thus controlling the possibili-
ties for data access. Access rights for stations of the process
control system and operator privileges for blocks can both be
set up. Configurable change logs permit the recording of all ac-
cess operations to the engineering system as well as all online
changes concerning the automation systems, operator systems,
SIMATIC BATCH or SIMATIC Route Control.
If the modification reports are linked to the data of SIMATIC Lo-
gon during evaluation, it can be clearly proven who has carried
out a specific modification and at what time. Such verifications
are often the object of special sector-specific requirements, for-
mulated, for example, in FDA 21 CFR Part 11 or GAMP.
SIMATIC Manager
The SIMATIC Manager is the control center of the engineering
system. It is the integration platform for the engineering toolset
as well as the configuration basis for all engineering tasks of the
SIMATIC PCS 7 process control system. All aspects of the SI-
MATIC PCS 7 project are created, managed, archived and doc-
umented here.
The engineering toolset contains tools which are optimally
matched to one another for system-wide project-oriented engi-
neering, and which simultaneously provide the basis for asset
management of the I&C equipment. These include tools for ef-
fective engineering of the following components:
•
Control system hardware including distributed I/O and field
devices
•
Communication networks
•
Automation functionality for continuous and batch processes
(AS engineering)
•
Operation and monitoring functionality (OS engineering)
•
Mass data engineering and cooperation with CAD/CAE
planning tools
•
Diagnostics and asset management functionality
•
Batch processes, automated with SIMATIC BATCH
•
Material transport, controlled by SIMATIC Route Control
•
Safety applications (Safety Integrated for Process
Automation)
Technologists as well as process and production engineers can
carry out planning and configuration in their familiar environ-
ments when using this range of tools as well as predefined
blocks and charts.
The hardware required for use in a SIMATIC project, such
as automation systems, communications components and
process
I/O, is stored in an electronic catalog. The hardware can
be configured and configured using the HW-Config tool.
Creating hierarchy folders implements a project structure, the
plant hierarchy (PH). By storing CFCs and SFCs for automation
systems and pictures and reports for operator stations in a hier-
archy folder along with additional documentation, the configur-
ing engineer implicitly determines the hierarchical assignment.
Function blocks (FBs) and functions (FCs) can be encrypted
and decrypted with the S7-Block Privacy application to protect
know-how. Following encryption, the blocks and their attributes
can no longer be modified. Only the interfaces of the blocks are
then visible.
To implement the automation logic, standardized function blocks
must be combined with other blocks in the graphic configuration
tool CFC according to technological specifications. You can sim-
ply select predefined blocks or charts for this purpose from a
catalog and then position, graphically interconnect and config-
ure them in the working area. The process tag data relevant to
operation and monitoring, such as messages and variables, are
generated at the same time. The SIMATIC PCS 7 Logic Matrix
can be used for fast and easy creation of the interlock logic be-
tween various Control Modules/Equipment Modules.
Sequential controls permit control and selective processing of
the basic automation functions created per CFC by means of
changes in operating mode and status. Convenient editing func-
tions for the graphic configuration of sequential controls as well
as powerful test and commissioning functions are offered by the
SFC editor.
Complete SIMATIC PCS 7 projects or all project modifications
can be compiled in one working step and downloaded to the tar-
get systems involved, e.g. to automation systems, Operator Sys-
tems or SIMATIC BATCH. The engineering system automatically
ensures that the sequence is correct. The procedure is dis-
played and controlled in a central dialog.
A more effective method for less comprehensive changes to the
standard automation, e.g. addition or modification of single pro-
cess tags, is selective compilation and downloading at chart
level. This can be started from the technological hierarchy, from
the CFC, or from the chart folder.
The project engineer can recognize all changes since the last
download by their color, and the current chart states by means
of the corresponding symbols. The project engineer can make a
specific choice in a dialog form for selective downloading. In as-
sociation with the Version Trail, each download is automatically
followed by archiving.
In the case of blocks being executed on the AS 410 automation
system, it is even possible to change types during runtime by
means of seamless copying (TCiR).
