DeviceNet Scanner Module The 1747-SDN scanner module allows communication among an SLC 5/02 or higher processor and a maximum of 63 DeviceNet-compatible I/O devices. The scanner is the DeviceNet master, enabling information transfer with DeviceNet slave devices using the strobe and poll message mode. The SLC system supports multiple scanners in a single-processor chassis.
The 1747-SDN module supports:
• up to 150 words of input and 150 words of output data.
• all standard DeviceNet communication rates.
• the exchange of status and configuration data.
Backplane current (mA) @ 5V 500 mA
Network power source requirement 125 Kbps, 250 Kbps, 500 Kbps
Isolation voltage Tested @ 500V DC for 60 s
In system mode, the serial port also supports supervisory control and data acquisition (SCADA) applications. SCADA systems allow you to monitor and control remote functions and processes using serial communication links between master and slave locations.
When configured for user mode, the serial port supports ASCII devices. Use the SLC 500 ASCII instructions to send information to and receive information from these devices.
