4. Grounding is of particular importance for reliable stable operation Communication system characteristics may vary from system to system depending on the system environment and grounding method used The gateway has one logic ground located on the RS 485 terminal block which serves as the ground reference for both power and RS 485 communication signals The gateway is also provided with a chassis ground terminal adjacent to the RS 485 terminal block In order to ensure proper EMC behavior the chassis ground terminal must be connected to an appropriate ground Please be sure to consider the following general points for making proper ground connections Grounding method checkpoints 1 Make all ground connections such that no ground current flows through the case or heatsink of a connected electrical device 2 Do not connect the chassis GND terminal to a power ground or any other potential noise producing ground connection such as an adjustable speed drive s E terminal 3 Do not make connections to unstable grounds paint coated screw heads grounds that are subjected to inductive noise etc 18 ICES 7 LED Indicators The gateway contains several different LED indicators each of which conveys important information about the status of the unit and connected networks These LEDs and their functions are summarized here 7 1 Gateway Status The gateway has one dichromatic LED to indicate the status of the device On star

The DIN rail adapter Figure 6 can clip onto 35mm and G type rails To mount the gateway to a DIN rail clip the DIN rail adapter onto the DIN rail and mount the gateway on the screws the screws should already be seated into the adapter at the proper height Refer to Figure 7 Figure 8 and Figure 9 Figure 6 DIN Rail Adapter Figure 7 DIN Rail Adapter Attachment Figure 9 Example Installation Figure 8 Unit with Attached DIN Rail Adapter 17 icc 6 2 Wiring Connections Note that in order to power the unit a power supply must also be installed Refer to section 5 1 for more information 1 Mount the unit via the desired method refer to section 6 1 2 Connect the various networks to their respective plugs terminal blocks Ensure that any wires are fully seated into their respective terminal blocks and route the network cables such that they are located well away from any electrical noise sources such as adjustable speed drive input power or motor wiring Also take care to route all cables away from any sharp edges or positions where they may be pinched 3 Take a moment to verify that the gateway and all network cables have sufficient clearance from electrical noise sources such as drives motors or power carrying electrical wiring 4 Connect the power supply to the gateway s RS 485 terminal block on the terminals labeled POWER and GND Pay particular attention to the proper polarity 6 3 Grounding

The following paragraphs describe the configurable fields of a timeout object Database Address Enter the starting address in the database where the first data element of this timeout object will begin The maximum allowable database address depends on the designated Data Type Data Type The size and range of valid values for each data element in this timeout object For instance selecting 16 Bit Unsigned allows for a range of timeout values between 0 and 65535 each occupying 2 bytes in the database Similarly selecting 16 Bit Signed allows for a range of values between 32768 and 32767 also occupying 2 bytes in the database Select the desired data type from this dropdown Value Enter the fail safe timeout value that each database address encompassed by this timeout object will be automatically written with upon processing a timeout event triggered by a protocol 30 icc Length Enter the number of data elements for this timeout object The total number of database bytes modified by a timeout object is determined by the Length multiplied by the number of bytes in the selected Data Type 1 2 or 4 for 8 bit 16 bit and 32 bit respectively 8 3 2 Database Logic 6 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 d

13. the enable logic should be inverted This applies to both the evaluation of whether or not the operation should execute as well as resetting the enable value when the auto reset option is used Auto Reset Allows the enable value to be automatically reset upon completion of the operation The actual value written to the enable value depends on the other trigger options selected If no options are selected a value of 0 is written to the enable value If the inverted option is used a value of 1 is written to the enable value If the bitmask option is used each bit selected in the bitmask is written to a 0 or a 1 if the inverted option is used in the enable value Bitmask If this option is used it selects which bits in the enable value to evaluate Every selected bit in the enable value must be 1 or O when the inverted option is used for the operation to execute 8 4 Service Objects and Diagnostics Objects A service object is used by the gateway to make requests on a network when a master client protocol is enabled Each service object defines the services read 34 icc and or write that should be performed on a range of network objects of a common type The data from read requests is mirrored in the database starting at a user defined address if a read function is enabled When a value within that address range in the database changes a write request is generated on the network if a write function is enabled Specific servic

54. the gateway does implement a write first approach This means that the gateway will perform any outstanding write services before resuming its round robin read request cycle Additionally the database and service objects provide the added benefit of data mirroring whereby current copies of data values populated by a service object are maintained locally within the gateway itself This greatly reduces the request to response latency times on the various networks as requests read or write can be entirely serviced locally thereby eliminating the time required to execute a secondary transaction on a different network In order to facilitate the free scaling and conversion of native data values a user configurable multiplier and data type exist for some network configurations All network values are scaled by a multiplier prior to being stored into the database or after being retrieved from the database The data type is used to determine how many bytes are allocated for the value in the database whether the value should be treated as signed or unsigned and whether the value should be interpreted as an integer or a floating point number upon retrieval from the database A typical use of the multiplier feature is to preserve the fractional components of a network value for insertion into the database For example if the floating point value 3 19 is read by the gateway from a remote BACnet device then we could use a multipl
55. thod is used in those networks that define a byte order for how to interpret multi byte data within an array of bytes PROFIBUS for example defines a big endian order for multi byte data while DeviceNet defines a little endian order for multi byte data These networks exchange I O data by means of a bag of bytes approach whereas the gateway need not concern itself with where individual values are delimited within the array of bytes itself as this is determined by the sending or receiving nodes on the networks The bytes are 41 icc 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 system whereas data is exchanged by addressing a certain object to read or write data Modbus for example uses registers while BACnet uses objects such as analog values to exchange data When multi byte values are received by the gateway the bytes must be stored into the database in the order defined by the endianness selected Likewise when retrieving multi byte values from the database for the gateway to transmit the endianness selected will determine how the data is reconstructed when read from the database The selection of the correct byte ordering is crucial for coherent interaction between these two types of networks on th
