OPC 40540 UA for Additive Manufacturing

The OPC 40540 series was developed to facilitate the exchange of information between AM machines and software systems such as MES, SCADA, ERP or data analysis systems.

The OPC 40540 for Addit­ive Man­u­fac­tur­ing is based on the OPC UA for Machine Tools inter­face and takes AM-spe­cif­ic fea­tures into account.

This allows addit­ive man­u­fac­tur­ing machines from dif­fer­ent man­u­fac­tur­ers to be effi­ciently integ­rated into exist­ing and new pro­duc­tion land­scapes. The dif­fer­ent AM tech­no­lo­gies are taken into account in the spe­cific­a­tion and spe­cif­ic fea­tures such as just-in-time, on-site and high flex­ib­il­ity in pro­duc­tion net­works are thus sup­por­ted. The spread and suc­cess­ful use of addit­ive man­u­fac­tur­ing in industry is pro­moted in this way.
The spe­cific­a­tion cov­ers a sim­il­ar spec­trum of use cases to those of OPC 40501 for machine tools. Oth­er AM-spe­cif­ic para­met­ers such as job and com­pon­ent prop­er­ties, mater­i­al and con­sum­able prop­er­ties, and the mater­i­al cycle are made avail­able at the sys­tems’ interfaces.

OPC 40540 and VDMA 40540 were ini­ti­ated by a sub-work­ing group of the VDMA Addit­ive Man­u­fac­tur­ing Work­ing Group with about 200 par­ti­cip­at­ing companies.
The first ver­sion of UA4AM ini­tially only deals with the inter­faces of the print­ing sys­tems. The VDMA Addit­ive Man­u­fac­tur­ing work­ing group cov­ers the entire pro­cess chain, thus also gen­er­at­ing poten­tial for cor­res­pond­ing expan­sion of the Specification.
