32. the BACnet network stores the data into the database and sends the input data onto the DeviceNet network Figure 27 demonstrates the data flow from the BACnet network to the DeviceNet network through a gateway configured to use a little endian database Because the DeviceNet specification defines multi byte values within the byte array to be interpreted as little endian it is recommended that the database be configured for little endian byte order when using DeviceNet In the example analog value 0 has a value of 0x12345678 When the DeviceNet device receiving the input data from the gateway interprets the 4 bytes the resulting 4 byte value will be 0x12345678 thus successfully receiving the original value of the BACnet analog value object 145 tec BACnet Millennium Series DeviceNet Network Gateway Network Database Input Data Lower Addresses Analog Value 0 0x12345678 Higher Addresses Figure 27 BACnet DeviceNet Little Endian Conversely Figure 28 illustrates the consequences of configuring the database for big endian byte order using this scenario Once again Analog Value 0 has a value of 0x12345678 But now when the DeviceNet device interprets the 4 bytes of input data sent by the gateway the resulting 4 byte value is 0x78563412 thus receiving an incorrect value for Analog Value 0 Note that in this example as well the DeviceNet byte array is identical byte for byte to the database This example in conjunction

34. to end consistency of multi byte data between the two networks on the gateway To better understand how this byte ordering scheme works the following explains how the gateway stores and retrieves multi byte data to and from the database Data is stored into the database starting at the low address and filled to higher addresses The endianness determines whether the most significant or least significant bytes are stored first Let s look at some examples that demonstrate this This example shows how Database the hex value 12345678 is stored into the database a using a big endian byte Source Value at order Since the hex value 12 is the most significant at2 byte it is stored at address an a 3 a the lowest address Figure 19 Big Endian Storage This other example shows Database how the hex value 12345678 is stored into the database using a little endian byte Source Value order Since the hex value 78 is the least significant byte it is stored at the lowest address Figure 20 Little Endian Storage Similarly data is retrieved from the database starting at the low address The endianness decides whether the first byte is the least significant byte or the most significant byte of the multi byte number Here are some examples that demonstrate this 141 tec This example shows how Database the hex value 12345678 is retrieved from the E S database using a big att Destination Value 0x12345678
