Com­pact bidi­rec­tional data mem­ory mod­ule

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

Bal­luff’s com­pact, bidi­rec­tional data mem­ory mod­ule is ideal for tight mount­ing spa­ces. The com­pact mem­ory mod­ule with IP 67 pro­tec­tion is just 34 x 16 x 8 mm and can be used as a mem­ory stor­age de­vice on in­ter­change­able units such as milling heads on gantry type ma­chin­ing cen­tres.

This means the as­sem­blies can carry their ac­tual op­er­at­ing data along with them, says the man­u­fac­turer. An­other ad­van­tage is when a ma­chine is changed, all the data such as the num­ber of use cy­cles, shock and vi­bra­tion val­ues or lu­bri­ca­tion and oil change intervals are di­rectly loaded.

The work re­quired to in­stall and pa­ram­e­ter­ize the mod­ule is min­i­mal, prom­ises Bal­luff. Only a sin­gle stan­dard ca­ble is re­quired for sta­ble, fault-free, bidi­rec­tional data trans­mis­sion be­tween the milling head and con­troller. The ca­ble is con­nected to the milling head in­ter­face in the sys­tem ring. Data trans­mis­sion is noise-im­mune as well as re­sis­tant to EMC ef­fects. The mod­ule can hold a to­tal of 14 seg­ments of 64 bytes each.

Ma­chine op­er­a­tors will profit from the fact that when a milling head is switched from one ma­chine to an­other, all the iden­ti­fy­ing and us­age data will be au­to­mat­i­cally copied and loaded from the milling head mem­ory into the NC con­troller through a ca­ble. When main­te­nance or re­pair work is needed, the ser­vice per­son­nel can read out all the data from the mem­ory chip on a PC or lap­top and up­date it as needed. This gives the plant op­er­a­tor con­tin­ual and trans­par­ent in­for­ma­tion about the cur­rent sta­tus of the milling head.

Bal­luff says the IO- Link proves to be a key tech­nol­ogy for high- per­for­mance, space- sav­ing In­dus­try 4.0 con­cepts. www.demm.co.nz/reader- en­quiry #170206
