Ignition SCADA Cost for a Mid-Size Plant
Cost of ignition scada for mid size plant An Ignition SCADA system for a mid-size plant has a software cost that is easy to calculate and a project cost that is not. Inductive Automation publishes its list prices, and licensing is per server, so the software portion of a typical single-site system lands in the low tens of thousands of US dollars. Engineering, hardware and integration are scoped separately and vary widely with the plant What Is Ignition SCADA Architecture? Ignition SCADA architecture is the way one or more Ignition Gateways are arranged to connect to field devices, store data and serve operator screens. Inductive Automation uses the term system architecture for how the Gateway or Gateways are set up in a facility. The Gateway is the Ignition server, and everything else connects to it Core building blocks Field devices: PLCs, drives, meters and instruments on the machines. Gateway: the Ignition server. It includes a built-in OPC UA server for device connectivity, holds tags, alarms and security, and runs the modules you license. Database: a SQL database, or the Historian modules, that stores history, alarms and production data. Designer: the engineering tool where developers build tags, screens, scripts and alarm logic. Clients: web-launched operator screens that connect to the Gateway. Licensing allows unlimited clients, so adding operators does not add license cost. . How Does It Work? Architecture Machine and PLC layer. PLCs hold the real-time machine state, counts and faults. Connectivity layer. Ignition reads this data through OPC UA, device drivers or MQTT. OPC UA is a vendor-neutral industrial standard maintained by the OPC Foundation. Gateway and database. The Ignition Gateway runs tag logic, alarms and scripts. A SQL database stores production events, orders and history. MES layer. This layer turns raw signals into production meaning. For example, “machine stopped” becomes “downtime event, reason: changeover, order 4521.” ERP layer. ERP sends production orders down and receives confirmations and consumption back up. Common architectures Architecture How it is arranged Typical fit License impact Standalone One on-premise Gateway connected to a SQL database, PLCs and clients Where most users start; a single plant One server license Redundant pair A master and a backup Gateway Processes where downtime is costly Both nodes need a license Scale-out A front-end Gateway hosts clients; one or more back-end Gateways handle PLC communication and history Large plants with many devices, tags and clients One license per Gateway Hub and spoke Each site runs its own Gateway; a central hub collects history Multi-site companies One license per Gateway In a scale-out system, Gateways share tags over the Gateway Network, and performance is improved by adding another Gateway where needed. In hub and spoke, store-and-forward prevents data loss when a connection to the database drops, and each site keeps running with its own history, alarms and clients if the hub is unreachable. Analysis: for a mid-size plant, a standalone Gateway is the usual starting point. Add redundancy when an outage would stop production or lose data, and move to scale-out only when one server can no longer carry the devices, tags and clients. Design the architecture first, because it decides how many licenses you buy. Ignition SCADA Services Ignition is a platform, so most projects combine software with engineering services. The main service areas are: Service What it involves Typical output Architecture and sizing Choose standalone, redundant or scale-out; size servers, databases and networks Architecture diagram and license list Device connectivity Connect PLCs and legacy equipment through OPC UA and device drivers Tag structure and tested connections Application development Build HMI screens, alarms, trends, reports and user roles Ignition project Historian and data Configure history, database tables and production or downtime data Data model and historian setup Migration Inventory screens, tags and alarms of an older SCADA, then plan the cutover Migration plan and parallel run Integration Connect MES, ERP, databases and MQTT-based IIoT platforms Documented interfaces Training and support Operator and engineer training, site acceptance testing, support plan Trained team and handover None of these has a published price, so service cost is scoped per project. INGSOL’s work spans SCADA, MES, IIoT, OT-IT integration and brownfield modernization, which are the areas these services draw on. Ignition SCADA Starting Price Starting point What you get List price (USD) Platform only Core Gateway; add modules later $1,200 Platform + Application Building suite Web-based screens (Perspective) and reporting $14,700 + Industrial Historian suite Adds stored history $18,200 + Alarm Management suite Adds alarm notification $21,400 Ignition’s starting price is US$1,200 for the platform license, based on the vendor’s published list price. That covers the core Gateway only; operator screens, reporting, historian and alarm notification are added as modules or suites. The totals are our calculations from published prices, before support, taxes, hardware and services. Annual support adds 16% to 24% of the retail price; on the $14,700 option that is $2,352 to $3,528 a year. You do not have to buy everything at once. Modules and suites can be added later, and if you convert modules into a suite you pay the suite’s retail price minus the retail value of the modules you already own. A free, fully functional trial lets you prototype first, and Ignition Edge suits small, single-project needs. Confirm current prices and module needs with Inductive Automation or an integrator before budgeting. How Is Ignition SCADA Priced? Ignition is licensed per server, not per tag, client or designer. One server license gives unlimited clients, tags and connections, so cost does not rise as you add screens, operators or data points. Standard Ignition and Ignition Edge licenses are perpetual, one-time purchases, while Ignition Cloud Edition carries a usage-based fee. The limit is hardware, not the license: a server can be overloaded if pushed too hard, so large plants often use several servers, and each server needs its own license. In practice, a mid-size plant’s software cost is built from four parts: the platform license, the modules it needs, an optional redundant license, and an annual support plan.
