8 Simulation Introduction ■ Overview 8/2 Siemens ST PCS 7.1 · September 2005 At present, the products listed below are available for testing and simulation of an entire SIMATIC PCS 7 system or individual process control levels (automation level, field level ...): • S7-PLCSIM SIMATIC PCS 7 standard product for the function testing of CFC/SFC application software on PCs/PGs; See main catalog ST PCS 7 for description and ordering data • SIMBApro FAT SIMATIC PCS 7 add-on product for field bus simulation (PROFIBUS DP and PROFIBUS PA), including numerous functions for the factory acceptance test (FAT) at unit level • SIMIT SIMATIC PCS 7 add-on product for dynamic plant simulation, e.g. for the overall plant test or the operator training.
■ Overview The system for field bus simulation with numerous functions for the factory acceptance test (FAT) SIMBApro FAT is based on the SIMBApro PCI simulation system. This permits simulation of the distributed I/O (PROFIBUS DP and PA) up to unit level. Aggregate typicals (valves, motors, etc.) are preassembled for the factory acceptance test of plants. Import functions for the construction of the distributed I/O (hardware configuration) and for aggregate wiring (symbol table) enable FAT solutions to be created quickly and conveniently. ■ Application Configuration/engineering • Early detection and clearance of configuration errors • Early testing of project-specific blocks (technological function, alarm behavior) • Early testing of sample solutions (e.g. sequencers) Factory Acceptance Test • Shortening the commissioning period thanks to tested configuration • Test without modifying the original software • Test of elementary automation functions (measurement and control loops, switching function) • Integration test of the entire automation architecture • Test of safety-relevant functions (emergency shutdowns) • Documentation of the test results • Simulation tools such as SIMIT can be linked for plant simulation Simulation SIMBApro FAT: Field bus simulation ■ Function • PCI technology • Baud rate: max.12 Mbit/s for PROFIBUS DP • 2 x 125 slaves can be simulated • Redundancy or 2 PROFIBUS DP buses • Standard slaves and S7 slaves • Library available for standard typicals • Generation of own simulation functions (typicals) • Import functions (HW-Config., symbol table) • Definition of import filters • Generation of distributed I/O faults Factory acceptance test at unit level The PC module SIMBApro PCI simulates the complete behavior of I/O devices on the fieldbus. The simulation is reaction-free, i.e. for the bus master there is no difference between communication with real and with simulated I/O devices. During the Factory Acceptance Test it is therefore possible to test the entire automation structure from the operator station to the driver connection and the hardware configuration. The simulation of the distributed I/O is extended in SIMBApro FAT to include functions for the Factory Acceptance Test (FAT). Using the PC program, feedback signals from units (valves, pumps, switches) can be generated in less time by importing them from the STEP 7 / PCS 7 symbol table. Apart from normal plant operation, fault states can also be simulated. All diagnostic options of the PROFIBUS are available, ranging from missing or incorrect feedbacks to distributed I/O faults (failure of module, station or line). SIMBApro FAT offers a library of easily configurable unit typicals for fast and reliable simulation of units. This enables feedbacks from valves, motors etc. to be generated in a simple manner, and this process can be automated by importing a symbol table. It is possible to set up a simulation for the factory acceptance test (FAT) in a very short time. Users also have the option of creating their own library elements in order to take the special requirements of their plant into account. If the requirements for the simulation extend beyond the FAT functions (e.g. overall plant test), a plant simulation system (e.g. SIMIT) can have read and write access to the data in the I/O devices.
