The standard engineering software provides the basic function-

ality for configuration of SIMATIC PCS 7 plants with: 
• Automation systems
• Process I/O
• Communication networks
• Operator systems
• Maintenance station
• SIMATIC BATCH
• SIMATIC Route Control
Licensing of the standard engineering software depends on use 

of the engineering station as:
• Classic, exclusive engineering station (not suitable for pro-

ductive operation as an operator station)

• Combined engineering/operator station for small applications 

(suitable for productive operation as an operator station)

Three software versions with unlimited POs are available for the 

classic engineering station:
• AS/OS - for engineering of automation systems (AS) and

operator systems (OS)

• OS - only for OS engineering
• AS - only for AS engineering
With the OS and AS/OS software versions, the OS configuration 

can be tested in an OS test mode limited to 2 hours. This OS test 

mode is not suitable for productive operation. After 2 hours, the 

engineering station automatically switches to demonstration 

mode.
The AS/OS software version is additionally upgraded by adding 

an AS runtime license for 600 POs. 
By means of a Rental License limited to 30 days for AS engineer-

ing or OS engineering (unlimited POs in each case), a cost-ef-

fective alternative is offered for short-term projects or short-term 

capacity bottlenecks. 

To support compact process control plants, an ES/OS software 

combination of limited volume is offered with 250, 1,000 or 2,000 

POs. In addition to the engineering licenses, these "All-in-one Li-

censes" also contain runtime licenses for AS and OS with the 

corresponding volumes. 
PowerPacks enable further expansion of the volume:
• From 250 POs to 1,000 POs
• From 1,000 to 2,000 POs

(in each case including AS/OS runtime license)

• From 2,000 POs to unlimited POs

(only with OS runtime license)

Essential tools of the standard engineering software and their 

functions:

Together with the versatile recording facilities provided by the 

modification logbook, SIMATIC Logon, the user administration 

and access control function used in the engineering system, of-

fers plant owners exceptional system support when complying 

with FDA requirements. 
Using SIMATIC Logon, the administrator can assign specific ac-

cess privileges to groups of users, thus controlling the possibili-

ties for data access. Operator interventions in the engineering 

system as well as all online modifications which affect the auto-

mation systems, operator systems, SIMATIC BATCH or SIMATIC 

Route Control can be recorded in the modification reports. 
If the modification reports are linked to the data of SIMATIC 

Logon during evaluation, it can be clearly proven who has car-

ried out a specific modification and at what time. 

The SIMATIC Manager is the control center for engineering of the 

SIMATIC PCS 7 process control system. All aspects of the 

SIMATIC PCS 7 project are created, managed, archived and 

documented here. The tools for engineering of the hardware 

components, communication and application software are also 

called from here. 
The hardware required for use in a SIMATIC project, such as au-

tomation systems, communications components and process 

I/O, is stored in an electronic catalog. The hardware is config-

ured and parameterized using the HW-Config tool.
To create the automation logic, standardized function blocks are 

combined with one another in the graphic configuration tool CFC 

according to technological specifications. Predefined blocks 

(process tag types) or charts (example solutions) can be used 

for this purpose simply by selecting them from a catalog and 

then positioning, graphically interconnecting and parameteriz-

ing them in the working area. No detailed programming knowl-

edge is required, one can completely concentrate on the tech-

nological aspects of configuration. The process tag data 

relevant to operation and monitoring, such as messages and 

variables, are generated at the same time as configuration of the 

automation functions.
Sequential controls permit control and selective processing of 

the basic automation functions created per CFC by means of 

changes in operating mode and status. Powerful test and com-

missioning functions for the graphic configuration and commis-

sioning of sequential controls 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. automation systems, operator system 

or SIMATIC BATCH. The engineering system automatically en-

sures that the sequence is correct. The procedure is displayed 

and controlled in a central dialog.
Selective configuration modifications can be downloaded online 

to the corresponding target systems. Short turnaround times re-

sult in short waiting times for the commissioning engineer, and 

have a favorable effect on the commissioning costs. Program 

modifications relevant to automation systems can be initially de-

bugged in a test system prior to downloading to the target sys-

tem of the running plant.
