Building an M580 Safety System Using Extended Local Racks
Using the BMXXBE1000 extender modules and cables, you can add to your M580 safety PAC:
up to seven extended racks to the local main rack.
one extended rack to a remote main rack.
Example of an Ethernet local main rack with extended racks and extender modules and cables:
