OPC 40086 defines inform­a­tion mod­els for mater­i­al sup­ply sys­tems in the plastics sec­tor. The entire path of the mater­i­al from silo to the pro­cessing machine is covered. The spe­cific­a­tion deals with the hand­ling of gran­ules, powder or liquids in a mater­i­al sup­ply sys­tem and addresses sys­tems of vary­ing com­plex­ity. Fur­ther more, all pro­cess data gen­er­ated dur­ing the pro­cess in
the mater­i­al sup­ply sys­tem should be recor­ded and made avail­able to oth­er systems.

OPC 40086 cov­ers the fol­low­ing functionalities:

• Gen­er­al inform­a­tion about the Mater­i­al Sup­ply Sys­tem and its mater­i­als: e.g. filling level, tem­per­at­ure etc. Each of the devices has a mater­i­al input (incl. con­di­tion) and a mater­i­al output.
• Job man­age­ment: The deliv­ery of mater­i­al by the MSS is organ­ized by jobs. For each job, a tar­get machine is pre­scribed, and the MES orders mater­i­al accord­ing to a defined recipe which is provided at a spe­cified trans­fer point.
• Trace­ab­il­ity: An event is gen­er­ated for each batch part that leaves the MSS. This con­tains a unique iden­ti­fi­er, which can later be used to determ­ine the his­tory of the sup­plied materials.
