What this panel PC is and what it brings to the line
The Siemens 6ES7717-0....-0... is a rugged industrial panel PC built for the factory floor, not a desk. It ships with an Intel Core i5-6440EQ (2.7 GHz to 3.4 GHz, 4 cores) or i7-6820EQ (2.8 GHz to 3.5 GHz, 4 cores, hyper-threading) processor, DDR4-SDRAM SO-DIMM memory in two slots configurable from 8 GB up to 32 GB, and an SSD storage option up to 1 TB — both the SSD and hard disk are field-replaceable without a service call. The 300 cd/m² non-reflecting display and integrated 87-key QWERTZ/QWERTY or AZERTY keyboard make it usable under plant lighting. WiFi 802.11ac and dual Gigabit Ethernet ports with independent MAC/IP addresses handle connectivity to the control network and the office LAN without a separate switch. It carries CE, UL, and CSA approvals, and is built to ISO 9001 standards — development and production are in Germany.
What the key specs mean for a sourcing decision
The 802.11ac radio means you get real-world throughput around 400–600 Mbps on a clean 5 GHz channel — enough for HMI screen pushes or recipe downloads without pulling a cable. The dual Gigabit Ethernet ports with separate MAC/IP addresses let you isolate the machine-level traffic from the plant IT network on the same physical unit. The SSD up to 1 TB is easy to replace, which matters when the unit lives on a moving gantry or a washdown cell — you can swap the drive in minutes without a depot repair. The 8.8 Ah lithium-ion battery is also field-replaceable, and one USB Type A port charges a smartphone even when the unit is switched off. That covers unheated warehouses and warm cabinet interiors, but the gradient limit means you cannot blast it with a heater after a cold soak.
Where this class of panel PC is used
This is a machine-mount or swing-arm panel PC for HMI, SCADA, or edge-computing tasks on a production line. The 385 mm width, 275 mm depth, and 53 mm height fit standard 19-inch cabinet cutouts or VESA-mount arms. The retractable handle and backpack option make it practical for a mobile maintenance cart or a test bench that moves between cells. It runs Windows 7 Ultimate 64-bit SP1, and STEP 5 software V7.23 HF2 is available as an option — that is the classic Siemens PLC programming environment, so this unit can serve as a programming terminal for legacy S5 systems without a separate laptop.
The Windows 7 operating system is a legacy OS — Microsoft ended mainstream support in 2015 and extended support in 2020. If your site requires a currently supported OS, factor that into the specification. The hardware itself is current-generation (Intel QM170 chipset, DDR4, 802.11ac) and the SSD and battery are user-replaceable, so the unit can be kept in service with spares.
