A powerful CPU is useless if it cannot talk to the plant floor. Industrial Ethernet is the standard, but the hardware to support it is often on backorder.
- 1756-EN2T & 1756-EN3T: These advanced EtherNet/IP communication modules are the lifelines of the ControlLogix system, supporting real-time I/O messaging, motion control, and HMI connectivity. Due to their universal necessity, they are often the hardest to find. Massive PLC currently has significant quantities of both factory-sealed and fully tested refurbished EN2T and EN3T modules ready for immediate shipment.
- Legacy Networks (ControlNet & DeviceNet): We have not forgotten plants running older networks. We have restocked 1756-CN2R (ControlNet) and 1756-DNB (DeviceNet) modules to support legacy field device communication.
