Hi Friends.
I need help about network for Step5. I need conect a CPU 155U with Ethernet Card CP1143 to my laptop, I have installated simatic Net 2000.
I am working with Inat H1 protocol and this connection working very well, but my idea is connect we old program Step5 7.23 by network to our PLC s5.
another question, I can connect Step5 7.23 by virtual Com to our plc...???
