The CPS-MG341-ADSC1-111 is CONTEC's compact, fanless M2M gateway that bridges serial Modbus RTU devices, digital I/O, analog sensors, and counter inputs to Ethernet-based Modbus/TCP and higher-level SCADA or cloud platforms. Built on an ARM Cortex-A8 processor running Linux, it provides all configuration and monitoring through a built-in web server — no additional software installation is required. The "-ADSC1" suffix designates the variant with analog input (2-ch, 0–20 mA, 12-bit) and counter input (2-ch, 24-bit) capabilities, differentiating it from the base DS1 model that provides only digital I/O and serial/Ethernet communication.

How does the CONPROSYS gateway connect legacy serial devices to modern networks?

The gateway operates as a Modbus RTU master on its RS-422A/RS-485 port, polling up to 1,000 Modbus data mappings from connected serial devices — sensors, meters, PLCs, or I/O modules — and simultaneously exposing that data as a Modbus/TCP slave on its dual Ethernet ports. The RS-485 port features full bus isolation (500 VDC) with surge protection via TVS diodes (±13 V, 400 W peak pulse) and a gas discharge tube arrester (±300 V, 2,000 A impulse), protecting the gateway from transient voltages on long fieldbus runs in industrial environments. Support for BACnet server/client and HTTPS data transfer enables direct integration with building management and cloud IoT platforms without protocol gateways.

What PLC brands and protocols can the gateway communicate with?

The CONPROSYS platform supports simultaneous communication with up to 10 PLC links across different manufacturers, accessing data from up to 30 PLCs and 100 group registers. The built-in web task script editor provides a flowchart-style logic builder that runs directly in the browser — no separate programming software or SDK required — enabling operators to create data transformation, alarm routing, and conditional logic without traditional PLC programming knowledge. The message communication function supports generic RS-232C, RS-485, and Ethernet TCP/UDP messaging with up to 10 concurrent links for custom protocol integration.

Frequently Asked Questions

Can this gateway operate in environments without climate control?

Yes. The CPS-MG341-ADSC1-111 is rated for -20 to +60 °C operation with a fanless design and contains no electrolytic capacitors or primary batteries — components that are common failure points in industrial electronics exposed to temperature cycling. This makes it suitable for installation in unheated equipment cabinets, outdoor kiosks, and rooftop telecom enclosures where commercial-grade networking equipment would fail. The tool-less removable terminal connectors allow quick field replacement without rewiring.

Does the web-based configuration require Java or browser plugins?

The built-in web server uses a Java applet for the flowchart-style task editor. For routine monitoring and configuration of Modbus mappings, a standard web browser without plugins is sufficient. The gateway also supports simple router functions — DHCP server, static routing, port routing, and IP routing — allowing it to serve as a lightweight network gateway for small remote sites where a full router would be excessive.
