The Allen Bradley 1747-SDN is DeviceNet scanner module. It is compatible with the SLC-5/02, SLC-5/03, SLC-5/04, and SLC-5/05 processors of the SLC 500 series. The 1747-SDN DeviceNet scanner module lets you connect low-level devices straight to the plant floor. The need of incorporating an I/O interface device is eliminated. The 1747-SDN DeviceNet scanner module provides extra diagnostic features which enhance data collection and/or fault detection. Moreover, with the 1747-SDN, less wiring than usual is required.
The 1747-SDN facilitates communication with a maximum of 63 DeviceNet-compatible I/O devices. The 1747-SDN module holds a maximum of 150 words of input and a maximum of 150 words of output data. It supports all standard DeviceNet communication rates, exchange of status, and configuration data.
The 1747-SDN draws a backplane current of 500mA at 5V DC and it has a network power source of 90mA at 24V DC. It has a communication rate of 125Kbps, 250Kbps, and 500Kbps at 24V DC. Its isolation voltage is tested at 500V AC for 60 seconds and its DeviceNet-to-backplane isolation voltage is 24V. The 1747-SDN has a minimum thermal dissipation of 2.50W and a maximum of 2.5W.
The 1747-SDN is programmed and communicates with the processor using the M0 and M1 data files that reside in the module. Generally, the 1747-SDN interfaces DeviceNet devices with SLC-5/02 or higher processors. Over the network, the 1747-SDN reads and or writes data to DeviceNet devices, downloads configuration data, and monitors the operational status of devices. The 1747-SDN can be used as a bridge between a DeviceNet network with other networks.
The 1747-SDN gets or delivers data to or from devices using poll, strobe, change-of-state, and cyclic messages. To connect the 1747-SDN module to the device network: 1. Turn off the network power supply. 2. Connect the DeviceNet drop line to the 10-pin linear plug (match the color insulation tables). 3. Insert the 10-pin linear plug into the DeviceNet connector located on the front side.
