Swipe Card Bar Code Readers
« on: November 30, 2004, 04:19:59 PM »
I'm interested in installing a swipe card reader to the MD-1616. Can anyone recommend one they might have used and (I know this is pushing it) share some code...

As long as your bar code reader has an RS232 port and can output data in CR terminated ASCII format it is a piece of cake to read it into the PLC's RS232 port using the

A$ = INPUT$(1)

command. Once the data is read into PLC, you have at your disposal all the commands needed to extract the data or convert into numbers.
