With the SITRANS Library SIMATIC software, process instruments of the SITRANS and SIPART product families can be integrated into the SIMATIC PCS 7 and SIMATIC STEP 7 process control system with high quality, efficiency and security. Integration takes place graphically via CFC (Continuous Function Chart) with APL/IL (Advanced Process Library/Industry Library)-based function blocks. Block icons and faceplates are available for representation in the operator station. Their design is also based on APL/IL.

The Library offers significant advantages in the life cycle of a plant. Important device functions are available both in the engineering phase and for process control. The visualized device functions are selected exclusively with regard to optimized process control. Commissioning and maintenance of the field devices is still performed with SIMATIC PDM.

The SITRANS Library can be used with SIMATIC PCS 7 version V8.0, V8.0 with update 1, V8.0 SP1, V8.1, V8.1 SP1 and V8.2 and V9.0 SP1.

To download the software free of charge and for a list of currently supported devices, please visit Industry Online Support.

For SIMATIC STEP 7 the Library is now also compatible with version V5.6.
