General Instructions Regarding Working with Application Materials A-1 Appendix A General Instructions Regarding Working with Application Materials Definition of Terms Application materials can be e.g. thermoplastic hot melt materials, adhesives, sealants, liquid adhesives and similar application materials. They are referred to as materials. NOTE: The materials that may be processed with your Nordson product are described in the manual under Intended Use and Unintended Use.
A-2 General Instructions Regarding Working with Application Materials Vapors and Gases Ensure that vapors and gases do not exceed the prescribed limits. If necessary, exhaust vapors and gases and/or provide sufficient ventilation of the work space. Substrate The substrate should be free of dust, grease and moisture. The suitable material, optimum working conditions, and possible pre-treatment of the substrate must be determined by testing.
Index Protocols and Communication Data List B-1 Appendix B Index Protocols and Communication Data List General Information The field bus interface provides the ability to centrally compile data for further processing. Appendix B applies to the PROFIBUS field bus. For better comprehension, only the pair master/slave is used in the text. The Nordson melter is the slave, the customer’s control system the master. The customer’s control system must provide a suitable interface.
B-2 Index Protocols and Communication Data List Control Modes (contd.) Field Bus In Field bus mode, the master controls the melter: S Control access only from master. Control via the interfaces Standard I/O and Key-to-line. S Parameter input only via master S On the control panel, all parameters can be displayed but not changed. Data Interface When data is exchanged between the master and Nordson melters, the data is accessed via indexes (Data index).
Index Protocols and Communication Data List B-3 The following illustrations show an example of the retrieval of actual temperature values. The master sends a transmission data block to the Nordson melter. The data block contains a job that the Nordson melter is to process. Field bus Transmission data block (command) Master / scanner Nordson melter Job: Read actual temperature values The Nordson melter replies to each transmission data block with a receive data block.
B-4 Index Protocols and Communication Data List Data Block Processing The master formulates a job by determining the transmission data block. The Nordson melter processes the job and formulates the reply (receive data block). The master processes the data or repeats the job until a reply is received from the Nordson melter. Only one job is processed at a time. The Nordson melter keeps the reply available until the master formulates a new job.
Index Protocols and Communication Data List B-5 Index Protocol and Data Image The data blocks are always the same length. The sequence of the data image must be followed (1st block: outputs, 2nd data block: inputs). NOTE: Add the assembly CP 342−5 to the S7 hardware configuration of the customer’s master. Add a universal board to position 1.

Index Protocols and Communication Data List B-13 Command (contd.) Communication Monitoring If the job identification is 0 (zero) and the melter is in Field bus mode, Field bus communication failure is indicated on the control panel. Possible faults S Programming error. The master was programmed incorrectly with Command=0. S Field bus cable broken, defective or not connected S Interruptions in communication, e.g.
B-14 Index Protocols and Communication Data List Channel Number The master has to determine a channel number that is valid e.g. for a temperature channel, pressure channel or motor. Beginning with the determined channel number as starting channel, the command to read data for six sequential channels is executed. The range of channel numbers extends from 0 to 18. Channel number set to ”0” (zero) is interpreted as No channel number.
Index Protocols and Communication Data List B-15 Read Data Value In Read data value the master reads the data values received from the Nordson melter. The Read data values of six sequential channels are transmitted with every receive data block (Refer to example). Example 1 The master reads the actual temperature values {120}. Channel number is set to 9.
B-16 Index Protocols and Communication Data List Example 2 (Standard Index Protocol) If the master sets Data index to 0 (zero) in the transmission data block, the Nordson melter sets all Read data values to 0 (zero). The master sets Data index to 0 (zero). Status of the Nordson melter is System ready. Transmission data block: Melter control Command Data index Channel number Write data value Line speed value (key-to-line) for motor 1 ... 0 2 3 4 ...
Index Protocols and Communication Data List B-17 Example 4 The Nordson melter sets invalid Read data values to 0 (zero). The Nordson melter has three motors. All motors run at a speed of 26.3 min-1. The master reads the actual speed {36}. Received data: E 2007 Nordson Corporation Data index Motor 36 1 263 dez (26.3 min-1) 2 263 dez (26.3 min-1) 3 263 dez (26.
B-18 Index Protocols and Communication Data List Line Speed Value for Motor 1-n (Key-to-line Mode) Line speed value for motor 1-n consists of additional values in the transmission data block. They need not be set by the master. This data is required only for motors working in key-to-line mode. The range of values extends from 1.0 to 100.0 %, and the transmission data must always be multiplied by a factor of 10 for transmission. Line speed value for motor 1-n set to ”0.
Index Protocols and Communication Data List B-19 Example of Startup with Standard Index Protocol For indexes and bit positions, refer to Communication Data List. 1. Set the main switch to I/ON. NOTE: The control unit needs some time to boot after the melter is switched on. No data can be exchanged via the field bus during this time. 2. With Profibus: Set the field bus address on the control panel. Other field buses: Set the address on the gateway. 3.
B-20 Index Protocols and Communication Data List Example of Startup with Standard Index Protocol (contd.) 5. When the system is ready for operation, start the motors. To do this, check the Status of the receive data block, e.g. by cyclically retrieving bit 0 System ready. When the system is ready for operation (All temperature channels are heated, no errors), all motors that were previously enabled can be started with bit 1 All motors ON (collective enable) in Melter control.
