Abstract

A method (100) for providing communication between multiple software components (2a-2d) in an industrial control system (1) using a common data store (3) holding a set of to-be-communicated variables (4), wherein• the common data store (3) is divided into multiple sub-sections (3a-3c),• each to-be-communicated variable (4) resides in at least one such sub-section (3a-3c), and• each software component (2a-2d) is configured to write values of variables (4) as outputs to the common data store (3) and read values of variables (4) from the common data store (3) as inputs,the method (100) comprising the steps of, in response to a request of one of the software components (2a-2d) to write a value of a variable (4) to the common data store (3), or to read a value of a variable (4) from the common data store (3):• determining (110), based on an identifier of the to-be-written or to-be-read variable (4), the sub-section (3a-3c) of the common data store (3) in which the to-be-written or to-be-read variable (4) resides;• determining (120), based on an address assignment (3a#-3c#) for this sub-section (3a-3c), a memory location (4a) of the to-be-written or to-be-read variable (4); and• modifying (140a) the to-be-written variable (4) at this memory location (4a), respectively reading (140b) the to-be-read variable (4) from this memory location (4a).
