I have found 3 programs for plc1774. These are TopDoc, AI-2 and PLC Communicator. But I don't have any of them

.
I have terminal and plc cable 1774-TC. I can type my PLC program but it very difficult

.
I understood how plc communicate with PC

. I made cable for it. I can send and receive data from PLC to PC.
So anybody have software TopDoc, AI-2?
Pls!!!
