The ABB 1SAP501800R0041 is a DigiVis 500 supervisory software license configured for 250 OPC signals. It is classified as Software_Media, meaning the order code covers the license and distribution media for the runtime or engineering station.
The DigiVis 500 is a PC-based supervisory control and data acquisition (SCADA) package from ABB's earlier generation. The 250 OPC signal count defines the runtime tag limit — it connects to controllers via the OPC DA or HDA protocol, not through a proprietary fieldbus. This is the Operations variant, meaning it is the operator workstation license, not the engineering or development seat.
