The ABB 1SAP501800R0101 is a software media license for the DigiVis 500 supervisory system, specifically an expansion that increases the OPC tag count from 100 to 250 signals. This is a software-only product — no hardware or frame size applies. It is classified as Software_Media, originating from Germany.
What the obsolete status means for your system
If you are maintaining an existing DigiVis 500 installation that needs this OPC expansion, the part is functionally correct — it raises the signal count as designed. The risk is supply continuity: once the surplus channel dries up, there is no official replacement path from ABB. Plan a migration to a current supervisory platform before the next major system refresh. The DigiVis 500 product line itself has been superseded; this expansion license is a bridge, not a long-term solution.
