Escort Memory Systems Unique Solution:
Using Escort Memory System’s HF-0405 integrated RFID controllers and GWY TCP Ethernet interfaces to read and write to Escort Memory Systems HMS108 tags, Stratus Automation designed a conveyor system meeting all of Seagate’s requirements including:
1. 100% Reliability
2. Detailed record of material movement within a facility
4. High speed communications to host computer
5. Read and write to tags
This was accomplished by placing HF 0405’s at each decision point along the conveyor system. At each decision point, Escort Memory Systems HMS108 RFID tags imbedded in the cassettes are read and the information sent back to the host computer. The host computer determines which path the cassette should take based on the routing information for that lot. It a cassette is determined to be in the wrong location for some reason, data is written to the tag that identifies it as being out of sequence. This data is recognized by each subsequent HF 0405 and the cassette is automatically routed to a holding area to await dispositioning. Because this process occurs in real-time, the cassette will be caught by the host system as being out of place before it is actually processed. This allows it to be placed back into the system at the correct location and moved to the correct next step; avoiding scrapping out of the cassette full of discs.
Up and Running
Stratus’ results to date show more than 15,000 read/write cycles without any failures for each HF 0405 connected to several GWY TCP Ethernet interfaces. Steve Ng, Project leader for Stratus Automation had this to say, “We saw over 15,000 reads without a single read failure with the HF-0405’s and GWY TCP’s. We’ve also seen the wiring reduced, and setup is fast”.
