1799-DNETSCON

The 1799-DNETSCON connector is a DeviceNet connector manufactured by Allen-Bradley as part of the 1799 Embedded I/O series of modules and components. This 5-pin phoenix connector features an open-style enclosure with a low environmental protection rating and it has a screw terminal as well as a jack screw. The 1799 embedded I/O modules and components such as the Allen-Bradley 1799-DNETSCON DeviceNet connector are well-matched and compatible with the SLCs, PLCs, and the SoftLogix programmable controllers when they are used with the DeviceNet scanners. For the 1799 embedded I/O module communication options, these embedded input and output modules serve as slave devices in a master and slave communication setup. They have I/O data that is exchanged by using the master device via either a polled, change of state, or cyclic connection.

The Allen-Bradley 1799-DNETSCON connector's connection type is selected through the configuration of the DeviceNet scanner module. It is polled whenever it is configured as a polled device, and the master device enhances communication through sending its polled input and output messages to the embedded I/O modules and devices like the 1799-DNETSCON DeviceNet connector. When the cyclic operation is used, the master device sends data to embedded input and output modules and it only receives the data from the embedded I/O modules at a preset time interval. This unit is 75 percent smaller than the RJ45 connector and it has a 10 millimeters connector pitch that provides greater port density. It also has shielding through the mated pair cables to provide an excellent level of EMI immunity because it is intended for use in electrically noisy environments. This unit has 2-point metal latching which offers extremely robust mating to help prevent accidental disconnection, and its latching is more durable than the RJ45 latching.
