Hello, I am attempting to connect a HID Signo 20 card reader to a Scada Pack 474.

The card reader only has 2 different protocols. One is the Wiegand which is a 2 wire analog signals or Open Source Device Protocol (OSDP). OSDP communicates over RS-485. But once the reader is set to OSDP it become a slave device and all control function need to be set by the controller. Is there a way to write commands to the RS-485 buffer to initiate the control of the device?

Has anyone done access control to a PLC?
Thanks!
