SCADA is licensed by tag count, and the tag count is the number that has to be established before anything can be priced. It is not the same as the IO count: a physical input often becomes several tags once its alarm limits, its calculated values and its historian points are added, and a project scoped on IO alone routinely arrives at licensing that is a tier too small. Establish the tag count, the number of concurrent client sessions and the historian retention period together, because those three drive both the licence and the server sizing. The second half of the enquiry is the part that is easy to defer and expensive to retrofit: segregation between the control network and the business network, remote access if any is required, and how the system is backed up and restored. Standards for industrial cybersecurity exist for this and a specification that names one is much easier to quote against.
The more of this you send, the closer the first quotation lands.
| Tag count | Total tags, not IO points — alarms and calculations add to it |
|---|---|
| Client sessions | Concurrent operator, engineering and view-only clients |
| Historian retention | How long data is kept and at what logging rate |
| Controllers to connect | PLC and RTU families, and their protocols |
| Protocols | Modbus, OPC UA, IEC 60870-5-104, IEC 61850 or another |
| Redundancy | Server, network or hot-standby redundancy required |
| Network segregation | How the control network is separated from the business network |
| Remote access | State if any is required, and by whom |
| Cybersecurity requirement | State the standard or maturity level your specification names |
| Reporting | Shift reports, regulatory reports, and the export formats needed |
| Server and client hardware | State if hardware is in scope or supplied by others |
| Engineering scope | Configuration, graphics, database build and commissioning |
| Support | Licence maintenance, updates and the support term required |
