What is SCADA Software?

The main purpose of SCADA software is to control and monitor industrial processes. This can be a complex task as there are several processes running simultaneously. SCADA systems are used in power, water and oil distribution systems, and are aimed at processing real-time data. They are also used for remote plant operations. They can also be used to monitor and control a wide range of other industrial processes.


The price of SCADA software can vary greatly depending on the features you need. A basic package can cost as little as $1,000 while more expensive versions can cost as much as $10,000. The price will also vary depending on the number of clients connected to your system. Many vendors offer different pricing options for their products, so it is important to compare prices.

The initial cost of a SCADA software package will vary based on the size of the system. Larger systems may require more engineering hours than smaller ones. For instance, a system for a site with a capacity of 200 megawatts will require 60% more engineering time. Moreover, a larger system will require more sophisticated controls, more engineering configuration, and more PLC logic development time.


SCADA software functions enable the management of industrial processes through data communications. These systems are composed of numerous hardware and software components and are used to collect, process, and display information from a variety of remote field devices. These systems also allow operators to change the operational state of these devices. This chapter covers the hardware and software functions of SCADA systems, as well as the user interface that is used to control the devices.

SCADA functions provide enhanced visibility into processes and data collection, allowing operators to make real-time adjustments to equipment and processes, without visiting the facility. These systems can adjust operations at the level of individual processes and machines, as well as the entire facility.


SCADA software security is an important component of SCADA operations. Without proper SCADA software security, SCADA systems can be vulnerable to attack and theft. This is especially true when new devices are combined with older systems and incorporate new technologies such as IoT and cloud. For this reason, cybersecurity must be a top priority from the very beginning of system development, during deployment, and throughout operations.

SCADA software security requires a holistic approach to security. Basic SCADA security practices include limiting access paths and establishing a physical separation from the business network. It also requires a proper security administration. This includes documentation of all application and hardware components, as well as the users that have access to data. This documentation will help determine any gaps in security.

Distributed topology

Distributed SCADA software can be configured with multiple servers in a dual-redundant or hot-standby topology. This allows users to maintain control of their plant even if one of the servers goes down. These servers can also store SCADA client applications in a database. They receive data from their control systems through serial port or MODBUS RTU protocols. The servers can also be configured to address users that do not have Internet access.

In a hybrid SCADA system, both the control center and field site communicate with one another. The field site also includes a remote access capability for operators to perform diagnostics via a dial-up modem. Typically, proprietary communication protocols are used to send data between the field sites and control centers. Telemetry techniques can include telephone line, cable, microwave, or radiofrequency techniques. Different implementations use different communication topologies to achieve different objectives.

Cloud-based solutions

Cloud-based SCADA software can benefit a variety of industries and applications. It lowers infrastructure costs and provides access to processing power, storage capacity, and security measures. The software can also be customized for specific use cases. Its versatility also enables companies to increase the technical functionality of mobile devices. With more people choosing smart devices, the interest and adoption of cloud-based solutions is increasing.

With its flexible deployment options, Cloud-based SCADA software can help companies manage their assets remotely. Samsara can support multiple protocols and provides an intuitive UI to users. It also allows unlimited number of users, configurable permissions, read-only access, and diagnostic analytics.
