This topic provides two methods on setting up the Standard Interface communication based on the EtherNet/IP protocol between a Mitsubishi MELSEC iQ-R Series PLC (with the RJ71EIP91 Network Interface Module) and the Mech-Mind Vision System.

  • Use PCI-e card.

  • Configure the software. No card required.

You should choose one of the methods to set up the communication. You cannot choose both methods.
