Buffer Overflow". Additionally, the sniffer is able to detect receive errors on the serial port such as parity, overrun, and framing errors. If a receive error occurs on one or more characters of a packet, the sniffer will output the characters “ERR: Receive Error”. Note that because the serial sniffer mode captures packets at the protocol driver level, a protocol must be configured on the selected serial port to provide data to the USB virtual COM port. - Page 30 Clearing the Capture Log All captured data may be cleared at any time while connected to a device or after disconnecting from a device. This will also reset the connection time duration and all counters. To reset all captured data, perform one of the following actions: •...

8.3.2 Database Logic 8.3.2.1 Overview A variety of database logic operations are included which provide PLC-style manipulation of database values. Categories such as logical, arithmetic and filtering operations allow for autonomous control over value modification and data movement within the database. High-level signal conditioning is also realizable via the construction of compound formulas derived from the elemental building block operations provided. - Page 35 • The Indirect Copy operation outputs the value at the database location specified by the input source to the database location specified by the output destination. This operation can be used to access different database locations dynamically. It could also be used to create reusable database logic subroutines by selecting a different input and output location for the subroutine during each execution cycle.
- Page 36 • The Cosine operation calculates the expression cos(Input 1), where Input1 is in radians. • The Tangent operation calculates the expression tan(Input 1), where Input1 is in radians. • The Arc Sine operation calculates the expression sin (Input 1), where the output is in radians.

Page 37: Service Objects And Diagnostics Objects
database operation can be used for this purpose, such a scenario may most typically use the output of a “compare” operation in order to control whether or not other operations should execute (e.g. execute a certain operation only when some process variable is greater than a certain value, etc.) Allowing the conditional execution of database logic operations to be based on data values obtained via communications or as a result of other database logic operations enables the construction of flexible, hierarchical and dynamic data evaluation and... - Page 38 Master/client drivers commonly also provide the ability to debug configured service objects while the driver is running by way of optional diagnostics objects. Where supported, diagnostics objects can be added to each service object, and a database address can be designated at which to store the status information. The diagnostics object is a 16-byte structure containing elements such as a transmission counter, receive counter, receive error counter, current status, and the last error of the defined service object.

Page 43: Appendix A: Database Endianness
12. Appendix A: Database Endianness A key feature of the Millennium Series gateways is the ability to change the byte order storage scheme for data in the database between big endian and little endian. The database endianness is the convention used to store multi-byte data to or retrieve multi-byte data from the database. - Page 44 Similarly, data is retrieved from the database starting at the low address. The endianness decides whether the first byte is interpreted as the least-significant byte or the most-significant byte of the multi-byte number. Here are some examples that demonstrate this. Figure 12 shows how the hex value 0x12345678 is retrieved from the database using a big endian byte order.

Page 45: Modbus - Profibus Example
simply stored into the database in the order they were received. Gateway endianness selection therefore has no effect on data storage or retrieval with a “bag of bytes” protocol driver. The other method is that used by networks that exchange data by means of an “object value”... -
Page 46: Modbus - Devicenet Example
In contrast, Figure 15 shows the effects of configuring the database for little- endian byte order. Holding registers 1 and 2 again have values of 0x1234 and 0x5678, respectively. However, when the PROFIBUS device receiving the input data from the gateway interprets these values, the resulting pairs of 2-byte values become 0x3412 and 0x7856, thus receiving incorrect values for holding registers 1 and 2. -
Page 47: Bacnet - Devicenet Example
For this reason it is important to configure gateways that use a bag-of-bytes style network, such as the DNET-1000, to use the same endianness as defined for that network. Figure 17: Modbus - DeviceNet Big Endian 12.3 BACnet - DeviceNet Example... - Page 48 reads analog value 0 from the BACnet network, stores the data into the database, and sends the input data onto the DeviceNet network. Figure 18 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.

Page 49: Bacnet - Modbus Analog Element Example
Figure 19: BACnet - DeviceNet Big Endian 12.4 BACnet - Modbus Analog Element Example This example exhibits two networks that both use an object value scheme to exchange data. In this scenario, the database endianness is irrelevant if the data types are the same for both networks. -
Page 50: Bacnet - Modbus Binary Element Example
Figure 21: BACnet - Modbus (Analog Objects & Registers) Little Endian 12.5 BACnet - Modbus Binary Element Example This example also contains two networks that both employ an object value method for exchanging data, but unlike the previous example, the database endianness does affect the end-to-end alignment of the data. - Page 51 Figure 22: BACnet - Modbus (Binary Objects & Discretes) Little Endian However, when the database is configured for a big-endian byte order, binary values 1…8 correspond to coils 9…16, binary values 9…16 correspond to coils 1…8, and so on. This can be seen in Figure 23. Since the most significant bytes of the Modbus registers that the coils map to are now mapped to lower addresses, the alignment between the two networks’...
