# Edge Computing Edge computing places computation and control near devices and data sources; it matters here as the scale where industrial controllers, networks, fleets, and cloud operations converge. ## Historical and Technical Context This page accurately recognizes the convergence embodied by Opto 22’s [[groov EPIC|groov EPIC]]: a Linux-based real-time industrial controller, gateway, HMI platform, and modular I/O system in one edge device, with UL hazardous-location approval and ATEX compliance. [S15][S34] The note is not merely product copying; it identifies a structural change in industrial automation. Traditional PLC, HMI, gateway, and computer roles are collapsing into a **programmable edge controller** capable of local logic and cloud communication. Galil extends the map into deterministic multi-axis motion control and robotics. ## Role in Scanned_20260730-1802 The primary identifying evidence appears on PDF page 32. A dense industrial-technology page. The heading expands IIOT. A location note points toward “Business Park Drive.” Product names and model numbers descend into a prose definition of an industrial controller. A final branch points to Galil motion controllers. Within that page, Edge Computing helps the notebook move from a visible name or artifact toward the underlying identity, protocol, ownership, or control structure. ## Notebook Evidence - `Scanned_20260730-1802.pdf`, PDF page 32: "Groov EPIC Edge" **Evidentiary status:** Visible evidence: correct expansion of EPIC’s functional stack. Verified fact: groov EPIC combines Linux control, HMI, gateway, and I/O. Strong inference: the author was surveying local Temecula-area industrial companies or facilities, possibly along Business Park Drive. The canonical name **Edge Computing** is normalized outside the quotations. The quoted lines preserve the completed reconstruction's spelling, capitalization, and uncertainty markers. ## Relationships On PDF page 32, Edge Computing appears in the same evidentiary cluster as [[Industrial Internet of Things|Industrial Internet of Things]], [[Opto 22|Opto 22]], [[SNAP PAC|SNAP PAC]], [[groov EPIC|groov EPIC]], [[Programmable Logic Controller|Programmable Logic Controller]], [[Human-Machine Interface|Human-Machine Interface]], [[Galil Motion Control|Galil Motion Control]]. These links record page-level proximity and the reconstruction's systems map; they do not by themselves prove corporate ownership or a direct technical dependency. ## Cross-Notebook Significance This is the industrial-scale analogue of pages 5-6 and 28-29: provisioning, firmware, identity, and programmable interfaces move from phones and USB boards into machines, fleets, and factories. ## Missed Signals and Open Leads Resolve `Groov-AR1` versus the actual GRV-EPIC model designation, the uncertain related acronym, and “rev32 axis.” Map the Temecula location to contemporaneous Opto 22 or partner facilities. ## Sources - [[Scanned_20260730-1802|Scanned_20260730-1802]], especially PDF pages 32, 33, 34, 35, 37. - `Scanned_20260730-1802.pdf`, cited as a plain archival filename; the PDF is not stored in `wiki-notes`. - **[S15]** Opto 22, “groov EPIC System”. https://www.opto22.com/products/groov-epic-system - **[S34]** Opto 22, groov EPIC press release, February 14, 2018. https://documents.opto22.com/2291_Press_Release_groov_EPIC.pdf
