The aXlink100 interconnects Ethernet with Profibus, in which Xlink, a real time Ethernet protocol developed by AutomationX, is used. The aXlink100 incorporates two Ethernet interfaces, which are available as 8P8C (RJ45) or optic fibre option, as well as a Profibus-DP master interface. These interfaces allow a multiplicity of system and network configurations. Therefore this equipment allows the configuration of an electrical ring via CAT5 cabling or a network and/or server redundancy via switches in a star layout network with this equipment. Thus it is possible to link up to 16 Profibus Master (aXlink100) with up to 124 Profibus-DP slaves per unit to automationX.
