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.
Control Modes
The modes Standard and Field bus are available in conjunction with the
option Field bus communication. The mode can be changed only on the
melter control panel.
Standard
S Control access only from control panel and from external control signals
via the interfaces.
S Parameter input only via control panel
S On the master, all parameters can be displayed but not changed. The
master can read actual values.
S AND link for switching on the motors (Refer to section Operation, Initial
Startup)
