Why Cretek for SCADA Systems in South Africa?
Cretek is a South African SCADA integration company with deep expertise across Siemens WinCC, Inductive Automation Ignition, and Rockwell FactoryTalk View platforms. We design and deploy SCADA systems that give operators real-time visibility, control, and analytics across their industrial processes — whether it's a single production line or a distributed multi-site operation.
Our SCADA engineering services cover the full project lifecycle: requirements analysis, system architecture design, HMI screen development, alarm management per ISA-18.2, data historian configuration, reporting dashboards, and secure remote access setup. We integrate SCADA with existing PLC networks (Siemens, Allen-Bradley, Delta, Modbus, OPC UA) and legacy systems to unify your operations under a single pane of glass.
We serve clients across Gauteng, Johannesburg, Pretoria, Boksburg, and nationwide — from municipal water treatment SCADA upgrades to mining remote operations centres and manufacturing production dashboards. All our SCADA systems are designed with cybersecurity best practices including network segmentation, role-based access, and audit logging.
SCADA Systems — Frequently Asked Questions
What is the difference between SCADA and HMI?▼
HMI (Human-Machine Interface) is the graphical interface that operators interact with — typically a single screen or panel. SCADA is a broader system that includes HMIs, data historians, alarm servers, reporting tools, and communication infrastructure to supervise an entire plant or distributed assets. A SCADA system contains one or more HMIs as part of its architecture.
Can you integrate SCADA with my existing PLCs?▼
Yes. We integrate SCADA with Siemens (S7-1200/1500 via S7 or Profinet), Allen-Bradley (ControlLogix/CompactLogix via EtherNet/IP), Delta (DVP/AS via Modbus TCP), Modbus RTU/TCP devices, OPC UA servers, and BACnet systems. Most integration is done via OPC UA for vendor-neutral connectivity.
Do you provide cloud-based SCADA solutions?▼
Yes. Ignition SCADA is web-native and can be deployed on-premises or in the cloud (AWS, Azure, or local data centres). We also implement cloud historian solutions where process data is replicated to cloud databases for remote analytics while maintaining local real-time control.
How do you handle SCADA cybersecurity?▼
We follow the Purdue model for OT network architecture. We implement DMZs between IT and OT networks, industrial firewalls (Moxa EDR, Siemens Scalance), VPN-based remote access, role-based user permissions, and comprehensive audit logging. All SCADA deployments include a cybersecurity assessment.
What is the cost of a SCADA system in South Africa?▼
Costs depend on tag count, number of screens, historian requirements, and integration complexity. A basic single-site SCADA with 500 tags and 10 screens typically ranges from R120,000-R250,000. A multi-site deployment with historian, 2000+ tags, and custom reporting can range from R400,000-R1,200,000+. Contact us for a detailed project-based quotation.
Can my SCADA system be expanded in the future?▼
Absolutely. We architect SCADA systems for scalability. Ignition's unlimited licensing model makes tag expansion cost-effective. WinCC allows modular server additions. We recommend scalable historian sizing and reserve capacity in servers and network infrastructure for future growth.
