How do I read a GSM SIM card CCID to Allen-Bradley PLC?
This application about USB Smart Card Reader and Allen-Bradley PLC with bridged by Arduino.
Communication between USB Smart Card Reader and Arduino using USB communication and then communication between Arduino and Allen-Bradley PLC using RS232 DF1 protocol communication.
I use MicroLogix 1000 for Allen-Bradley PLC and Arduino UNO plus USB host Shield.
Figure below describes this application:
