Card Reader for AB 5/04 & PLC 5/20 - PLCS.net

WireGuy1950 · January 10th, 2007, 09:15 AM

I would like some thoughts and information on using a serial card reader with the above AB processors.

The card reader would be for operator identification / parameter access.

The system will be networked, probably DH+.

Thanks

Well, both of those controllers have serial ports that can be programmed for ASCII input, so you could connect a serial card reader to one or several of them.

What exactly do you mean by "operator identification and parameter access" ?

It's unlikely that your HMI software or RSLogix software can be restricted by data values that are in the controller.

Describe more about your application needs.

Our machines currently have three access levels, one just allows operators to view the set-up parameters, one allows supervisors to change setup parameters, and another OEM level where we can change PLC constants.

Level two is currently reached via keyswitch, OEM level is reached via the same keyswitch and HMI password (On PV1000 / SLC 5/04).

The customer now wants his operators to use their ID bages to log into the press.

I envision that this login would be transferred to the new network, compared to a list and then the appropriate secuity level would be sent back to the press.

This way we could differentiate between regular operators and supervisors and maintenance people, basically overriding the keyswitch.
