As machines become more connected, machine builders increasingly face a practical networking challenge:<\/p>\n

The machine network and the factory network often serve very different purposes.<\/b><\/p>\n

At the machine level, controllers, I\/O modules, drives, and sensors may exchange data over a dedicated network using protocols such as Modbus TCP. At the factory level, SCADA, monitoring, or data acquisition systems may require OPC UA over a separate plant network.<\/p>\n

The data needs to move between these two environments \u2014 but the networks themselves do not necessarily need to be directly connected.<\/p>\n

For a conventional system, this may mean adding an industrial computer or protocol gateway along with additional networking equipment. The QEC-PPC-M-090T-S<\/b> provides a more integrated approach by combining a programmable HMI Panel PC with two independent Ethernet interfaces.<\/p>\n

\"QEC-PPC-M-090T-S\"<\/figure>\n

The diagram above illustrates the key difference: instead of adding separate devices between the machine and factory networks, the QEC-PPC-M-090T-S can sit directly between the two environments while providing the local HMI at the same time.<\/p>\n

The QEC-PPC-M-090T-S is more than a local operator interface. With two independent Ethernet interfaces, it can exchange data with the machine-side controller through Modbus TCP and provide selected data to factory-side SCADA or upper-level systems through OPC UA, while keeping the two network segments independent.<\/p>\n

Dual Ethernet and a Programmable Platform<\/h2>\n

The QEC-PPC-M-090T-S provides two independent Ethernet interfaces that can be assigned to different network roles:<\/p>\n

    \n
  • 1 \u00d7 10\/100 Mbps Ethernet (LAN)<\/b> \u2014 for connecting machine-side controllers and equipment networks.<\/li>\n
  • 1 \u00d7 Gigabit Ethernet (GLAN)<\/b> \u2014 for connecting factory-side SCADA, upper-level systems, or data networks.<\/li>\n<\/ul>\n

    The value of the dual-Ethernet design is not simply having an additional network port. It allows machine-side communication and factory-side connectivity to be configured on separate network segments according to the application architecture.<\/p>\n

    In the demonstrator described in this article, Modbus TCP and OPC UA are used to illustrate the two Ethernet network roles. They are application examples rather than fixed assignments for the interfaces; developers can select the communication methods and data flow according to the requirements of their own system.<\/p>\n

    At the same time, developers can use 86Duino IDE<\/b> to build the application in C\/C++, defining how communication, data mapping, and application logic operate between the two sides.<\/p>\n

    Dual Ethernet connects two different network roles; 86Duino IDE lets the developer decide how data is exchanged and used between them.<\/b><\/p>\n<\/div>\n<\/div>\n<\/div>\n

    Designed for On-Machine Deployment<\/h2>\n

    The dual-network architecture is supported by hardware designed for installation at the machine site. The QEC-PPC-M-090T-S uses a fanless design<\/b>, helping reduce fan maintenance and the active intake of airborne dust associated with forced-air cooling.<\/p>\n

    \u5176 \u524d\u9762\u677f\u5177\u5099 IP65<\/b> helps protect the operator-facing display and touchscreen against dust and water when the unit is properly installed in a panel or control cabinet. The IP65 rating applies to the front panel, not the entire enclosure.<\/p>\n

    For environments subject to temperature changes, the standard operating temperature range is 0\u00b0C to +60\u00b0C<\/b>, with an optional extended-temperature configuration of -20\u00b0C to +70\u00b0C<\/b>. Together, these features allow the QEC-PPC-M-090T-S to serve not only as an integrated HMI and protocol gateway, but also as an industrial Panel PC suited for direct deployment on machinery.<\/p>\n<\/div>\n<\/div>\n

    Bridge the Data, Not the Networks<\/h2>\n

    The key idea behind this dual-network architecture is simple: bridge the data, not the networks.<\/p>\n

    The QEC-PPC-M-090T-S does not operate as a transparent network bridge between the machine and factory networks. Each Ethernet interface can maintain its own network role, while the application determines what information crosses the boundary.<\/p>\n

    Machine data received through Modbus TCP can be processed and selectively mapped into OPC UA variables for the factory-side system.<\/p>\n

    The data can be exchanged while the two network segments remain separate.<\/b><\/p>\n

    For machine builders, this provides a practical way to keep machine communication focused on equipment operation while providing the information required by SCADA or factory-level applications.<\/p>\n

    It can be especially useful when connecting existing equipment to a plant network without redesigning the original machine-side network architecture.<\/p>\n

    A Working Dual-Network Application<\/h2>\n

    To show how this architecture works in practice, a working demonstrator was built around the QEC-PPC-M-090T-S rather than treating dual Ethernet as a theoretical feature.<\/p>\n

    In this setup, the QEC-M-070T remains the machine-side EtherCAT controller. It gathers I\/O data from an R11CFFG EtherCAT I\/O module and a Modbus RTU I\/O board, then exchanges process data and commands with the QEC-PPC-M-090T-S over Modbus TCP on the machine-side network.<\/p>\n

    On the factory side, the QEC-PPC-M-090T-S provides selected data through an OPC UA server, allowing an OPC UA client such as UaExpert or a SCADA system to monitor the machine from the factory network.<\/p>\n
