An adhesive dispensing device () includes a melt module () including a housing () that defines a receiving space to receive adhesive and a heater () to heat the housing to melt the adhesive, and a control module () releasably connected to the melt module. The control module includes a controller () to automatically recognize a characteristic associated with the melt module and operate the melt module using instructions stored on the controller that correspond to the characteristic of the melt module. A method of operating the adhesive dispensing device is also disclosed.

Systems and methods for improved liquid dispensing system communications are disclosed. In an example method for communicating control data between a plurality of component of a liquid dispensing system, a controller of a first component of a liquid dispensing system publishes a control data message to a composite controller associated with the plurality of component. Based on a classification of the control data message, a second component is determined to be a subscriber for the control data message. The composite controller then transmits the control data message to a controller of the second component.

Systems and methods for liquid dispensing system communications

A dispensing system includes a hot melt unit delivering heated adhesive through a hose to at least one dispenser gun, which is actuated by an outside source of gun actuation. Rather than directly connecting the source of gun actuation to the dispenser gun, the source of gun actuation is connected to the hot melt unit and then to the dispenser gun. For example, the gun actuation signals may be terminated at a terminal block in the hot melt unit, which enables the hot melt unit to monitor the gun actuation signals. The dispensing system is operable to perform various diagnostics pertaining to the dispenser gun and the system as a whole based on these monitored gun actuation signals.
