Systems and methods for direct heater diagnostics for a hot melt liquid dispensing system are disclosed. At least one of a current measurement or a voltage measurement is received from a respective current and/or voltage sensor positioned at an electrical circuit that supplies electric power to a heater associated with the dispensing system. The heater can be for an applicator or heated hose attached to the dispensing system, a melter of the dispensing system, or a pump of the dispensing system. A state of the electrical circuit is determined based on the at least one of the current or voltage measurement.

A flexible map with application data identifiers for PLC communications is described. An example method comprises receiving a first user input indicative of a selection of a parameter from a plurality of parameters associated with an adhesive dispensing system (). The parameter is subject to data exchange between a controller () of the adhesive dispensing system () and an associated programmable logic controller (). A second user input is received that is indicative of a memory space location in a memory space of the controller (). A custom data map is generated that is indicative of an association between the selected parameter and the memory space location.
