## Abstract

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 (614). The parameter is subject to data exchange between a controller (616) of the adhesive dispensing system (614) and an associated programmable logic controller (610). A second user input is received that is indicative of a memory space location in a memory space of the controller (616). A custom data map is generated that is indicative of an association between the selected parameter and the memory space location.
