Supervisory Control and Data Acquisition (SCADA) systems have become an integral part of modern industrial processes. They provide real-time monitoring and control capabilities that are essential for the successful operation of any process control system. When it comes to PLC (Programmable Logic Controller) projects, the right SCADA system can make the difference between a successful implementation and a costly failure.

How to Select SCADA for PLC Projects
When selecting a SCADA system for your PLC project, there are several key factors that need to be considered. These include scalability, reliability, security, integration, and user-friendliness. In this blog post, we will provide a checklist of these factors to help you make the right choice for your PLC project.
SCADA selection Criteria
Number of Tags
When selecting a SCADA system, the number of tags is an important factor to consider. The number of tags required depends on the size and complexity of the process. Smaller processes may only require a limited number of tags, while larger processes require a high number of tags to provide real-time monitoring and control of multiple process variables. It’s important to consider the current and future needs of the process, and ensure that the system is scalable and able to integrate with other systems and devices.
Alarm Configuration
When selecting a SCADA system, alarm configuration is an important factor to consider. Alarms are used to notify operators of process deviations or abnormal conditions. The system should have the capability to configure and customize alarms according to the specific needs of the process. It should also have the ability to prioritize alarms and provide real-time notifications via various means such as email, text message or pop-ups. Make sure that the system allows for easy management and tracking of alarms and their status.
Report Configuration
When selecting a SCADA system, report configuration is an important factor to consider. Reports provide valuable insights into process performance and can help identify areas for improvement. The system should have the capability to configure and customize reports according to the specific needs of the process. It should also have the ability to schedule and automate report generation, and export data in various formats such as PDF, Excel or CSV. Make sure that the system allows for easy management and tracking of reports and their status.
21 CFR Part Compliance
When selecting a SCADA system, compliance with 21 CFR (Code of Federal Regulations) is an important factor to consider. 21 CFR is a set of regulations enforced by the US Food and Drug Administration (FDA) to ensure the safety and efficacy of products used in the food, drug, and medical device industries. A SCADA system used in an industrial process that falls under 21 CFR regulations must be compliant with these regulations. It should have the capability to record and retain data, ensure data integrity and security, and provide the ability to generate and maintain electronic records and electronic signatures. It is important to work with a vendor that has experience and expertise in the regulated industries and understands the specific requirements of 21 CFR.
Application Requirement
When selecting a SCADA system, it’s important to consider the specific application requirements of the process. The system should be able to meet the control, monitoring, and data collection needs of the process. It should also have the capability to integrate with other systems and devices, such as PLCs, DCSs, and MESs. The system’s scalability, reliability, security, and user-friendliness should also be considered.
Communication Data Requirement
When selecting a SCADA system, data communication requirements are an important factor to consider. The system should have the ability to communicate with other systems and devices in the process, such as PLCs, DCSs, and MESs. This includes communication protocols such as Ethernet, OPC UA, Modbus, and DNP3. The system should also have the ability to handle real-time data transfer and provide remote access to data for monitoring and control. It’s important to consider the system’s scalability, reliability, and security in relation to data communication. The system should also be able to integrate with data analysis tools and cloud-based platforms. It is important to work with a vendor that has experience and expertise in the data communication field and understands the specific requirements of the process.
Scalability
The SCADA system should be able to accommodate the current and future needs of your PLC project. As your project grows and expands, the SCADA system should be able to adapt and scale accordingly. Consider the number of PLCs and remote devices that will be connected to the system, as well as the amount of data that will be collected and processed.
Reliability
The SCADA system should be reliable and able to withstand harsh industrial environments. It should be able to function smoothly and provide accurate data even during power outages or other critical situations. Look for systems that have built-in redundancy and fail-safe mechanisms to ensure maximum uptime.
Security
The SCADA system should have robust security features to protect against cyber threats and unauthorized access. This includes encryption, secure communication protocols, and access control.
Integration
The SCADA system should be able to integrate with other systems and devices in your PLC project. This includes integration with existing control systems, data analysis tools, and other software. Look for systems that offer open communication protocols and APIs for easy integration.
User-friendly interface
The SCADA system should have a user-friendly interface that allows for easy monitoring, control, and management of your PLC project. This includes real-time data visualization, alarms, and event logs. Consider the level of technical expertise required to operate the system, as well as the level of customization that is available.
Vendor Reputation
In addition to these factors, it’s also important to consider the vendor’s reputation and level of technical support offered. Look for vendors with a proven track record of delivering high-quality SCADA systems for PLC projects. Make sure to ask for references from other customers and to look at case studies of similar projects.
Conclusion: PLC Tutorial Point
When it comes to SCADA selection for PLC projects, it’s important to take the time to consider all of the key factors. By following this checklist, you can ensure that the SCADA system you choose will meet the current and future needs of your PLC project, and provide accurate, real-time data for optimal control and monitoring.
In conclusion, SCADA system is a crucial aspect of any PLC project, and choosing the right system is essential for the success of the project. By considering scalability, reliability, security, integration, and user-friendliness, as well as vendor reputation and support, you can make an informed decision that will help ensure the success of your
