POWERLINK included in EUROMAP specification
EUROMAP, the European association of plastics and
rubber machinery manufacturers, has included POWERLINK in the EUROMAP 75
specification, which recommends protocols for data communication with
peripheral equipment. It consists of three parts: EUROMAP 75-1 describes
profiles for measuring devices, EUROMAP 75-2 covers physical interfaces
and connection technology, and EUROMAP 75-3 focuses on the
implementation of real-time Ethernet systems, listing POWERLINK and two
more protocols. Product quality in injection molding largely depends on
the reaction times of both measuring chain and machine controller. A
precise adjustment of the holding pressure, for instance, which ensures
an even distribution of the melt throughout the die, requires pressure
and temperature data to be processed quickly. Even simple switching
operations require maximum reaction times of 0.5 milliseconds.
