Capability
PLC, HMI and SCADAfrom the machine to the plant network.
Most of the world's plants run on PLCs and SCADA, not DCS. We engineer them with the same discipline: written functional design, structured code, tested I/O, alarm philosophy and a network that is segmented before it is connected.
Small plants deserve serious engineering.
What ATG delivers
Scope we takeunder our own contract.
- Functional design specifications, I/O lists, network architecture and panel design.
- Structured PLC programming — machine, batch and process control — on Siemens, Rockwell, Schneider, ABB, Mitsubishi and GE platforms.
- HMI and SCADA application development to ISA 101 with alarm management, trending, reporting and historian.
- Distributed SCADA and telemetry — remote stations, pumping stations, compressor stations, pipeline links.
- Mixed-OEM line integration onto one plant network with protocol gateways and OPC UA / MQTT northbound.
- Panel build supervision, FAT, SAT, commissioning and long-term support.

Frequently asked
Questions buyers askbefore the shortlist.
Which PLC brands does ATG program?
Siemens, Rockwell (Allen-Bradley), Schneider Modicon, ABB, Mitsubishi and GE, with WinCC, AVEVA/Wonderware, FactoryTalk, EcoStruxure/Citect, zenon and InduSoft above them. Our recent Saudi work includes Marafiq Jubail IWTP-8 on Siemens S7 and Wonderware, and MODON Jeddah on Modicon M580 and AVEVA Plant SCADA.
Do you support existing plants as well as new projects?
Yes — troubleshooting, modification and support on running plants is a large part of our work, for example Almarai Al Kharj on Rockwell platforms and Hadeed Jubail on Siemens S7.
Can you connect our PLCs to the business systems?
Yes. Plant data concentration, historian, OEE dashboards and ERP interfaces are delivered through a segmented network and industrial DMZ — see the OEE & IIoT page.
Digitalisation, OEE & IIoT
