Typical migration scenarios
A large number of different migration scenarios is imaginable
depending on the specific technical and economical factors of
each migration project. The migration products offer the modularity
and flexibility required to implement such scenarios.
Typical migration scenarios which can be implemented using
these migration products:
Scenario 1: Replacement of existing HMI system by a
SIMATIC PCS 7 operator system
If the HMI (Human Machine Interface) system is technically
obsolete, if the stocking of spare parts is too expensive, if it no
longer complies with current directives and standards for operator
workstations, or if functional expansions are required
(e.g. IT integration), it is possible to simply replace the existing
HMI system by a SIMATIC PCS 7 operator system. The controller,
process I/O and application software are retained.
■ Minimum costs
■ Clear risk
■ Lengthening of service life of complete plant
■ New application possibilities
■ Opening of system for IT world
Scenario 2: Expansion of existing plant
The existing plant is initially retained, and is modernized by
expanding with further sections/units with SIMATIC PCS 7.
■ Simple, step-by-step increase in production capacity
■ Clear risk
■ Introduction of new technologies (e.g. PROFIBUS fieldbus,
HMI)
■ Opening of system for IT world
■ Together with scenario 1, enables process control using a
uniform operator system
