Integrated S5 Simulation PLC
With the Integrated S5 Simulation PLC, which is implemented in the basic S5 for Windows® software package, it is possible to test your S5 PLC programs.
No additional hardware is needed. The test will be performed on your PC.
The Integrated S5 Simulation PLC provides you with the same on-line status display as a real PLC, connected via a serial link.
The Integrated S5 Simulation PLC uses the commands from the Siemens 115U (CPU944) without system commands.
With the click of a mouse or with the keyboard you can set or reset Inputs, Outputs, or Flags directly within the on-line status display.
From the Integrated Simulation PLC Window the PLC program can be executed in single steps. The single step operation allows you to execute a single program cycle, a single Block, or a single instruction within a block.
You will find buttons to start, stop, and execute the start OB's.
Fields to display the value of variables (operands, timers, counters data words etc.) and fields to display and set inputs, outputs, and flags, are provided.
Extended S5 Simulation PLC
Optionally, an additional Extended S5 PLC simulation package is available.
The SimPLC PLC945 is a software simulation PLC with the functionality and the instruction set of a Simatic® S5 CPU 945, incorporating system commands, floating point values, and the use of double words.
Extended function blocks (FX), extended data blocks (DX), and extended flags (S .. 32 768) are also supported.
The number of timers and counters are extended to 256 each and the memory structure is equal to the memory structure of the CPU 945.
The Extended S5 Simulation PLC can be installed on the same computer where you have installed the S5 for Windows® software package which will allow you to transfer data directly between S5 for Windows® and the Simulation PLC.
It is also possible to have the Extended S5 Simulation PLC installed on a separate computer and transfer data between S5 for Windows® and the Simulation PLC's via a serial link between the two computers using a null-modem cable.
