SoftPLC S5-943 / S5-945

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 without any recompile activities. Since the SoftPLC behaves like a original SIMATIC® PLC, the programming tools S5 for Windows® and STEP®5 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.
