Frequently Asked Questions
Fusion.IO temperature slot cards are compatible with thermocouple (TC) or resistance temperature detector (RTD) sensing devices. Temperature readback measurements can be verified by comparing a known ‘sensed temperature’ readings issued by Fusion.IO using or DDI Studio EtherCAT software, or other approved EtherCAT software. Familiarity with TCs and RTDs functionality is required so always consult their manufacturer’s user or application guide before performing a test. Connecting a TC directly to resistive heating elements will lead to unpredictable results and potentially cause damage to the slot card.
Remote IO Modules, or RIMs, require a Fusion controller or RIM Control Module (RCM) to operate. The RIM is an extension of the SIL3 safety system, with its on-board safety logic devices directly connected peer-to-peer with the controller via RIM ports. Though the RIM is powered by its own 24VDC supply, the SIL3 safety system will default to a safe state if a condition arises that breaks the connection between the controller and RIM. If a RIM is disconnected from the controller, all of its on-board IO cards will be put into a safe state.
