Micro 1400 with an RFID Reader

[jayperkins 0]

I am trying to use my RFIDeas pcProx plus reader with my micrologix 1400. I know that the 1400 can send and receive strings. I want to read in the id number from the reader and send it to an external database. Can someone please point me in the right direction? Thank you

I am working on a similar project right now. ASCII serial keypad to ML 1400. I have worked out validating swiped cards, differentiating between swiped cards and keypad entries, moving keypad entries from string files into integer words. Now how can I take separate integer words (2, 4, 5, 0) and combine to get one integer (2450)? Love the forum BTW. Finally joined.

Ok, solved the integrating integer problem by using the # key to determine number of digits and then doing the math. As for Jay's question there is a sample program at Rockwell that helped me understand reading strings over serial connection. It is: [365]ASCII_Input.zip.
