Recommended action

Discontinued: order the successor 5069-L320ER from the manufacturer or your usual distributor by Jun 2028 (~$6,770, ~79 days + migration work). A used or refurbished 1747-L542 is only a stopgap.

Order by: June 2028
Fastest delivery: ~2 days + 14-day safety buffer before expected end of life
