SIPART controllers in higher systems
An important requirement for the safe control of process engineering plants is reliable monitoring.
Therefore the functions provided by modern process control systems include central operation and
monitoring using monitors. This possibility can also be implemented with the Siemens digital
compact controllers.
1. Up to 32 controllers can be connected via a serial interface to a correspondingly configured
personal computer (with CDOS 386, version 2.0 or CDOS XM, version 6.0 operating system).
The SIPART SW PC software enables process operation and monitoring as well as parameter
setting from the PC. The reliability of the single-loop controller is fully retained with this system
configuration since the personal computer is only used for operation and monitoring. Failure of
the PC has no effects on the process: all closed-loop controls, open-loop controls and
calculations are carried out by the compact controllers in autonomous mode.
The supplementary program "BATCH" is additionally available for recipe management.
Setpoints, states, parameters and structure switches of the controllers can then be stored on
floppy disks and reloaded from them.
2. The Siemens digital compact controllers are highly suitable for use in higher-level automation
systems both in SPC and DDC backup modes. For example, a software package "SIPART
SW S5" is available for communication between the compact controllers and the SIMATIC S5-
115U, S5-135U, S5-150U and S5-155U programmable controllers. The interface module at
the SIMATIC end is the CP 524 or CP 525-2 communication processor. A specially developed
driver enables data transfer for each interface with up to 32 compact controllers of any
configuration. Function blocks are also available for the above mentioned S5 programmable
controllers with which the user can control the data transfer. In this manner our compact
controllers can work together with the SIMATIC programmable controllers or can be connected
via the CP 526 to a monitor or to COROS 2000 for central operation and monitoring.
The facilities described above can be implemented using SIPART DR20. SIPART DR22
controllers. TELEPERM D universal controllers or the multifunction unit MFE. These
controllers can also be used together on one common bus providing the maximum of 32
controllers is not exceeded.
