I am working on a school project and is using a PLC(SLC500) with SLC 5/01 processor.
The PLC is connected to a conveyor system.
I need to monitor and control a ladder program that has been downloaded into the PLC.
By doing this, I need to read or write bits directly to the PLC.
The PLC has 1747-KE module installed. This module enhances the PLC with DF1 protocol.
I need to connect my PC's COM port to the DF1 port of the 1747-KE in order to monnnnitor the PLC.
To do this,
Do I need to use modems or just a regular Female-Female 9-pin serial cable to connect them directly?
I am writing a visual basic program that will read/write to PLC via DF1 protocol.
Please help,
Thank you,
Tom
