Use Bulletin 1784 Communication Cards with your SoftLogix™ controllers to monitor and control I/O on ControlNet™ or DeviceNet™ networks. Use your own Ethernet card to communicate over EtherNet/IP™ networks. Use the built-in serial port on your SoftLogix controller to communicate over RS-232 serial networks. Install multiple communication interfaces into the SoftLogix PC to configure a gateway to bridge or route control and information data between different networks.
