The SENECA Z-PASS2-RT-S is a multifunctional device designed for the evolving needs of Industry 4.0. It serves as an essential interface for remote control and data management, combining the features of a traditional PLC, an industrial router, and a sophisticated IIoT gateway into a single, DIN-rail mounted unit.

Secure Remote Assistance (LET'S Platform)

As a core component of the SENECA LET'S platform, the Z-PASS2-RT-S provides secure VPN (Virtual Private Network) connectivity via OpenVPN. This allows technicians to perform remote maintenance, firmware updates, and troubleshooting on factory equipment from anywhere in the world, as if they were physically connected to the local machine network. The built-in firewall and encryption protocols ensure that industrial data remains protected against unauthorized access.

Integrated Soft-PLC and Protocol Conversion

Unlike standard routers, the Z-PASS2-RT-S features a built-in soft-PLC. Compliant with the IEC 61131-3 standard (using the Straton runtime), it can execute complex control logic and manage local I/Os directly. Furthermore, it acts as a powerful protocol converter, bridging the gap between legacy serial-based Modbus RTU equipment and modern cloud-based SCADA systems via MQTT or HTTPS. This makes it an ideal tool for retrofitting older industrial plants for IIoT readiness.

Key Features

• Dual Ethernet Ports: Supports LAN/WAN configurations, enabling the separation of machine networks from the factory IT network for enhanced security.
• Built-in I/O: Includes 2 digital inputs and 2 digital outputs, which can be used for local control or to trigger remote alarms.
• Web-Based Configuration: The device is easily configured through a standard web browser, requiring no specialized software for basic setup.
• Data Logging: Capable of local data storage and scheduled transmission to remote servers via FTP or MQTT, preventing data loss during network outages.
• Robust Industrial Design: Fanless operation and wide operating temperature range make it suitable for installation in harsh factory environments.

Typical Applications

• Remote Machine Maintenance: Allowing OEM machine builders to support global customers remotely.
• Water and Wastewater Management: Remote monitoring of pumping stations and treatment plants via VPN.
• Renewable Energy: Data aggregation and remote control for solar farms and wind turbine arrays.
• Smart Building Automation: Connecting disparate HVAC and lighting systems to a central cloud management platform.
