The SoftPLC S5-943 / S5-945 executes a program in the same manner as a hardware PLC. The advantage of executing a PLC program this way is, that the PLC status can be displayed in real time. Since the SoftPLC behaves like a original SIMATIC PLC, the programming tools S5 for Windows® and STEP5 can be used. Online connections can be estasblished serial, via Ethernet and directly in the same PC. The program of a S5-PLC can be transferred to the SoftPLC S5-943 / S5-945.
The SoftPLC can access standard I/O boards as well as numerous intelligent hardware boards available to control bus systems widely used in the industry (PROFIBUS DP, DeviceNet, CAN-Bus). Drivers have been developed to connect bus system interface boards with the SoftPLC.
