1-6 Before You Begin Publication 1747-6.5.5 - August 2000 Different portions of data from a single device can be mapped to separate 1747-SDN memory locations. For example, “On/Off” values can be mapped to one location, diagnostic values to another, etc. This is known as “map segmenting”. This concept is illustrated by byte A, stored separately , as segments A1 and A2. 1747-SDN Scanner Module DeviceNet Devices Input Data Storage A1 B C A2 D E E Output Data Storage X Y Y Y Y Z Byte 0 1 2 3 4 5 6 input from the devices to the SLC 500 processor output from the SLC 500 processor Input Data From DeviceNet Devices A1 A2 Y B D E Output Data To DeviceNet Devices Y X Z C
Communicating with Your SLC 500 Processor An M1 file transfer is the transfer of data from the scanner to the processor. The scanner makes data collected from the network’s devices available for the processor to “read”, i.e., DeviceNet input data. An M0 file transfer is the transfer of data from the SLC 500 processor to the scanner. The processor “writes" data to the scanner's memory, i.e., DeviceNet output data. Before You Begin 1-7 Your processor communicates with the 1747-SDN interface module via M1 file transfer reads, M0 file transfer writes, and DIO transfers. Input data, gathered from the network’s devices, is organized within the 1747-SDN and made available for the processor to “read” from the M1 file. The 1747-SDN module does not send data to your processor. Data transferred between the scanner module and the processor must be initiated by the processor. Output data is sent, or “written”, to the scanner by your processor by placing the data in the M0 file. This data is organized in the scanner, which in turn passes the data on to the scanned devices via strobe, poll, change of state, or cyclic messages.
