I am not sure what you mean by going into program mode. Do you mean that the PLC goes into program mode when powered up with the NT screen?

Can you explain how you are connected to the PLC and the brand name of the PLC?
If it is an Omron then look into the Omron setup of the CPU. Sometimes you can specify the default state of the PLC when connected to specific ports.

If you disconnect from the PLC, and go into 'Transmit Mode' you will be able to download a new program into the screen.

Hope this helps,
Regards,
