DescriptionThe Profibus-DP, DeviceNet, and ControlNet fieldbus cards are used infieldbus systems to centrally collect and process data. The cards operatethrough the master-slave access method. When used in a fieldbus system,Nordson melters always operate as slaves.

Although most melter functionality can be set/monitored using fieldbuscommunications, some functionality is considered inconsistent with fieldbususage and is therefore not accessible. Non-supported melter functions are:S ClockS Password protectionS PID selection (DuraBlue melters only)S Motor-off delay (DuraBlue melters only)S Hose 1 and 2 solenoid activation (DuraBlue melters only)

Profibus-DP Card InstallationInstall the Card

See Figures 2 and 3.

Install the Profibus-DP onto the melter CPU board observing the followingguidelines:S Install the Profibus-DP card inside the melter electrical cabinet. Use a

two-wire connection: line A (usually green) and line B (usually red) mustbe the same on the entire bus.

S Route the bus cable out of the melter's electrical cabinet through anavailable conduit knockout (left side or base of the melter).

S To ensure smooth operation, end the fieldbus system with an active busterminator (terminating resistor) at the beginning and end of aProfibus-DP card segment.

S Nordson recommends attaching both ends of the bus cable screen toprotective grounding/functional grounding. When the potential is not thesame at both ends, an equipotential bonding conductor should be laid.

Optional FunctionalityCommunication Failure Alert

Melter fault code F4/E indicates that the melter has lost communications withthe fieldbus. Refer to the melter manual for troubleshooting information.

Melter Control Panel Lock-outWhen password protection (parameters 10 and 11) is enabled with a fieldbuscard installed, all operator panel controls are disabled.



Melter Operational ModesMelters with a fieldbus card have two operational modes: local and remote.The default is the remote mode. The mode may be selected through themelter operator panel.

NOTE: For the remainder of this manual, the term “fieldbus” is used to referto the Profibus-DP, DeviceNet, or ControlNet fieldbus system.

Local ModeThe local mode of operation is used mainly to view data for maintenance andrepair purposes. In this mode, the melter operates like a melter that does notinclude a fieldbus card:S Control access is only via the melter operator panelS Parameter input is only via the melter operator panelS Through the master, all parameters can be displayed but not

changed. The master can always read actual values.To place the melter in the local mode, change Parameter 14 (External CommLockout) to 1.

Remote ModeWhen the melter is in the remote mode of operation, it can be operated fromboth the master and the melter operator panel:S Setpoints and system parameters can be entered through the master

or the melter operator panel.S If control of the melter exclusively through the master is desired, you

can enable password protection (melter operating parameters 10 and11), which locks-out operation of the melter using the operator panel.Refer to the melter product manual for information on enablingpassword protection.NOTE: When a fieldbus card is installed in the melter, enablingpassword protection will disable all melter operator panel input,including the Heaters, Pump, and Standby keys.

To place the melter in the remote mode, change Parameter 14 (ExternalComm Lockout) to 0. This is the default setting.



Data InterfaceWhen data is transmitted from the Nordson melter to the master and viceversa, the data is accessed through indexes. The available data are shown inthe Communication Data List at the end of this section.

The use of indexes has two advantages. First, the communication data list isnot constrained by the fieldbus card's maximum data width. Second, theindexing method allows a smaller transmit packet, which prevents thefieldbus system from being loaded with unnecessary data.

Transmit and Receive PacketsCommunication is accomplished through two packet formats: transmit andreceive (from the viewpoint of the master). These packets are always16 bytes in length. Each packet format contains specific data blocks, asshown in Tables 12 and 15 later in this section.

The master sends a transmit packet to the Nordson melter. Figure 12 showshow the command for reading actual temperature values is communicated.

Figure 12 Example of master-to-melter communication



The Nordson melter sends a receive packet that includes status informationon the processing of the transmit packet command. Requested data valuesare also returned in the receive packet, as shown in Figure 13.

The master cannot formulate and transmit a new command until the receivepacket arrives.

Figure 13 Example of melter-to-master communication

Packet ProcessingThe master formulates a command and communicates it through the transmitpacket. The Nordson melter processes the command and formulates thereceive packet.

The master processes the data in the receive packet or repeats thecommand until a reply is received from the Nordson melter. Only onecommand is processed at a time. The Nordson melter keeps the replyavailable until the master formulates a new command.

When a command can not be executed, the Nordson melter replies bygenerating a fault signal in the status block. The master determines throughthis identification whether the previously transmitted command was correctlyprocessed by the Nordson melter.

The master must check that data in the the acknowledge data: data indexand channel number data blocks from the Nordson melter are the same asthe data in the transmit packet.

NOTE: The master may need to swap bytes in some or all of the packetdata if the data formats of the master and the Nordson melter do notcorrespond.

Melter ControlThe melter control data in the transmit packet is executed by the Nordsonmelter with each packet, regardless of the command type.

NOTE: Unused or reserved bits must be set to 0 (zero).

CommandThe master must send a command to the Nordson melter. Each command isdefined by a command identification.

Table 14 Command IdentificationsCommand Function

1 dec No command for the Nordson melter3 dec Master wants to read data from the Nordson melter6 dec Master wants to write data to the Nordson melter

Any other command identification is not valid and will generate acommunication fault in the status data block.

If the command is 0 (zero), a “host communication failure” will be generatedat the melter. This functionality operates for communication monitoring andmaster life guarding.

Data IndexThe indexes in the data index block correspond to those in theCommunication Data List at the end of this section.

The range of data indexes is 0 to 255. A data index set to 0 (zero) isinterpreted as “no data index.”

Channel NumberThe master must select a channel number that is valid. Refer to ChannelNumber List later in this section for the channel number descriptions (such asfor a temperature channel).

Beginning with the selected channel number as a start channel, thecommand for reading data is processed for the six successive channels.

Write Data ValueIn the write data value data block, the master writes the data values used toenter settings in the Nordson melter.

Example: Master sets the Ready Delay parameter to a value of 25 minutes.Transmit Packet Data Channel Number Value

0 No communication faults in data values



NOTE: Nordson melters are equipped with automatic Pump StartupProtection. The Pump Startup Protection prevents all stopped pumps (suchas those stopped as a result of an RTD fault) from starting up automaticallyafter finishing the heat-up phase or after a fault has occurred.To acknowledge the Pump Startup Protection, change the All PumpsON/OFF parameter from OFF to ON. (For a rising transition-based reset,refer toMelter Control. If bit1 = 0, then set to 1; if bit1 = 1, then set to 0 andsubsequently to 1 again.)

Read Data ValueIn the read data value data block, the master reads the data received fromthe Nordson melter. The read data values of six successive channels aretransmitted with each packet (where applicable).

Example:Master reads actual temperature values; channel number is setto 9.

Data SecurityData transfer occurs upon receipt of the transmit packet by the melter. Themaster can confirm correct data transfer by sending a read command in atransmit packet. The master cannot send a new command to the Nordsonmelter until a reply has been received.



Master ProceduresThese procedures apply to programming executed from the master.

Master: Determine Transmit Packet1.. Setmelter control.2.. Set command, data index, and channel number.3.. In case of a write command, determine the write data value.4.. Send the transmit packet to the Nordson melter.

Melter: Process a New Packet1.. Evaluate and executemelter control, command, data index, and channel

number.2.. In case of a read command in the transmit packet: set read data value.3.. Set received data index and channel number as acknowledge data.4.. Set status.5.. Provide the receive packet to the master.

Master: Evaluate the Receive Packet1.. Evaluate status.2.. Check acknowledge data: data index and channel number.3.. In case of a read command in the previous transmit packet: evaluate and

process read data value in the master application.
