PLCs, mark series

The Domat mark PLC series delivers robust multi-vendor BMS, HVAC, and gateway solutions for integrators facing the complexity of modern buildings and retrofit projects. Every controller in the lineup is Linux-based, engineered with Domat Runtime and open protocols such as BACnet, Modbus, OPC UA, and MQTT, as well as the IEC 62056-21 protocol for utility meters and PV systems, alongside the finely tuned proprietary SSCP protocol, freely available for integrators who choose to use it. This combination unlocks plug-and-play commissioning, scalable integrations, and risk-free upgrade paths in small to large sites.

Accelerate integration and subsystem management across offices, retail sites, plants, and energy systems. From high-I/O compact stations (markMX.3, markMXL) and serial-heavy gateways (mark520, mark320LX) to panel-mount LCD controllers (mark130.2), each device is designed for flexible topologies, with local HMI for service, native web/proxy for remote work, and secure architecture suited for layered networks behind VPN or routed LAN. Firmware and hardware features scale with project needs—from on-board I/O density (up to 88 points), .NET driver support, and advanced serial/Ethernet interfaces, to real-time monitoring, local history storage, and project-based IDE logic — all with comprehensive documentation.

All mark PLCs support open configuration, rapid multi-device commissioning, and vendor-specific driver options, enabling integrators to avoid lock-in, bridge legacy systems, and adapt to energy and automation trends. Each model is validated by strong Domat deployment record in offices, retail, industrial, and energy facilities across the EU, ensuring proven reliability and serviceability in live projects, while enforcing security standards (LAN/VPN/web access only, project-based logic in Domat IDE on Windows).

Feature set includes:

• High-density I/O (up to 88 inputs/outputs per station)

• Dual/quad serial and Ethernet interfaces for network flexibility

• Native local HMI (LCD display with manual keys) for streamlined service

• Full web/proxy suite for commissioning (no public exposure advised)

• Domat IDE logic programming (FUPLA, ST, .NET drivers per release notes)

• Hardware reliability: watchdog, RTC/NVRAM, storage, robust power & mounting

• All models with comprehensive documentation; consistent security guidelines for integrator use

Limitations: No controller is recommended for direct internet access—use behind router/VPN; not for unqualified environments (Domat provides free training and certification); project-based configuration is mandatory in Domat IDE (free license); always follow Domat security guidance for deployment.
