It is classified as software media, meaning the delivery is a physical or downloadable license key, not a perpetual seat. This part is now obsolete per the manufacturer's lifecycle status. ## Sourcing reality for an obsolete license Because this is a software license key, the usual surplus-channel rules for hardware don't fully apply. The license was originally tied to a specific installation; reactivating it on a new system may require ABB's legacy support or a transfer agreement. Sourcing this through independent distribution means the buyer provides the target system details so we can confirm the license key hasn't been consumed or locked to a previous host. ## What the expansion means for an existing DigiVis 500 installation The base DigiVis 500 system handles 500 OPC signal points. This license lifts that ceiling to 1000, which is the practical limit for a single-server supervisory node before you need to scale to a distributed architecture. If your process historian or alarm management is already bumping against the 500-point cap, this is the exact upgrade path — no hardware change, just the license activation.","metaTitle":"ABB 1SAP501800R0121 DigiVis 500 Expansion, Obsolete","metaDescription":"ABB 1SAP501800R0121 DigiVis 500 expansion license, increases OPC signal capacity from 500 to 1000 points.
