Product Overview

The Siemens 6AG4104-1AA02-1BX0​ is a SIPLUS ruggedized configuration of the SIMATIC RACK PC 547B, Siemens’ 4HU 19-inch industrial rack-mount PC platform designed for continuous operation in harsh production environments where standard commercial PCs would fail. The “6AG4” prefix identifies the SIPLUS (Siemens Plus) line—PCB conformal coating, extended temperature qualification (–25 °C to +60 °C ambient, vs. 5–50 °C on the standard 6AV781x IPC 547B), and component selection for 24/7 industrial duty. The “-1AA02″ config suffix denotes the specific hardware build: Intel Core 2 Duo processor (E8400/E8500 class, 3.0 GHz), 2 GB DDR3 RAM (1×2 GB, 1 slot free), 250 GB SATA 3.5” HDD, DVD-ROM optical, and the base I/O set. The trailing “-1BX0” designates the software/OS package—in this case a Siemens pre-install bundle (typically Windows XP Professional or Windows 7 Ultimate/embedded depending on build year) with Siemens SIMATIC device drivers pre-loaded, though many 1BX0 units shipped without a retail OS license and rely on the plant’s volume agreement.

The Siemens 6AG4104-1AA02-1BX0​ houses the motherboard in a shielded 4HU rack chassis with filtered 100–240 V AC supply (24 V DC redundant PSU option available on some 547B sub-configs), 2× Gigabit Ethernet, 4× USB 2.0 front + 4× USB rear, 1× DVI-I, 2× RS232/RS485 COM ports, and an expansion cage offering 1× PCIe x16, 1× PCIe x4, and 2× PCI slots—enough for PROFIBUS CP 5611/5621, PROFINET CP 1616, or analog I/O extension cards. Internally, the Siemens 6AG4104-1AA02-1BX0​ supports up to two 3.5″ SATA bays plus one SSD mounting point, with Intel Matrix RAID (RAID 0/1) capability—critical for PCS 7 OS server/client redundancy and WinCC historian nodes where disk loss cannot stall the line.

Although the IPC 547B platform dates to the 2010-era (Core 2 Duo / early i5 Clarkdale transitional period), the Siemens 6AG4104-1AA02-1BX0​ remains a heavily specified spare across PCS 7 v7.x and WinCC v7.x installed bases that cannot migrate to IPC 547D/647D without a full BOM/qualification cycle. The SIPLUS coating and extended-temperature envelope also make it the default choice for outdoor cabinet, foundry-adjacent, and hygienic/washdown-peripheral cells where a standard IPC 547B would drift.

Main Features and Advantages

SIPLUS conformal-coated ruggedization.​ The core differentiator of the Siemens 6AG4104-1AA02-1BX0​ versus the standard 6AV781x IPC 547B is the SIPLUS treatment: PCBs receive acrylic conformal coating, connector selections are screened for extended-temperature capacitors, and the thermal qualification pushes to –25 °C cold-start and +60 °C continuous (vs. 5–50 °C). For plants where the control room shares space with the process—foundries, glass lines, outdoor compressor stations, or desert solar-inverter yards—the Siemens 6AG4104-1AA02-1BX0​ survives where a bare IPC 547B would throw thermal throttling alarms by mid-morning. The coating also resists conductive dust and light caustic mist, extending mean-time-between-failure in pulp & paper and cement bagging lines.

PC/104-adjacent expansion depth without losing 19″ rack form.​ The Siemens 6AG4104-1AA02-1BX0​ keeps one PCIe x16 (for a display or profibus-accelerator card), one PCIe x4, and two PCI slots—a slot map that matters for PCS 7 and WinCC deployments. A typical PCS 7 client/OS server build uses the Siemens 6AG4104-1AA02-1BX0​ with a CP 5611 (PCI) for PROFIBUS DP connection to the AS-400 PLCs, a CP 1616 (PCIe) for PROFINET IO controller, and the x16 slot left open for a low-profile GPU if the WinCC faceplate count exceeds 5000 tags with trending. The PCIe x4 slot can also host a second CP 1623 for redundant PN IO. This expandability is why the Siemens 6AG4104-1AA02-1BX0​ remains on BOMs even as Siemens pushes the IPC 547D/647D—those newer chassis shift slot ratios (more PCIe, fewer PCI) and break CP 5611/5621 compatibility, forcing a CP migration the plant may not want.

RAID-ready storage for historian continuity.​ The Siemens 6AG4104-1AA02-1BX0​ ships with Intel Matrix Storage (ICH10R southbridge) supporting RAID 0/1 across the two 3.5″ SATA bays. In a PCS 7 OS server role, mirroring the 250 GB system disk (or upgrading both bays to 500 GB/1 TB and mirroring) means a single disk failure doesn’t take the AS-400 link down—the standby disk rebuilds overnight during low-activity. The third SSD mount (often used for the WinCC archive/SQL data partition) keeps random I/O off the mechanical mirror, a layout many Siemens 6AG4104-1AA02-1BX0​ deployments standardize on. Siemens also offers the “RAID 1 Advanced” firmware option on some 547B BIOS revisions, adding background scrub—worth enabling on 3-shift lines.

Core 2 Duo + 2 GB RAM is “just right” for PCS 7 v7.x / WinCC v7.x.​ This isn’t a knock—PCS 7 v7.1/v8.0 and WinCC v7.0/v7.2 were tuned against Core 2 Duo + 2–4 GB RAM. The Siemens 6AG4104-1AA02-1BX0​ hits the sweet spot: enough single-thread for the WinCC RT, enough L2 for the SQL Express local archive, and the E8400/E8500 65 W TDP keeps chassis temp manageable. Upgrading to the later IPC 547C (i5-660) or 547D (i5-4570) can actually trigger OS re-qualification on validated GMP/pharma lines where the Siemens 6AG4104-1AA02-1BX0​ is already signed off. For those sites, the AA02 config is a safe like-for-like.

Front-access USB + DVI-I + filtered PSU.​ Operator convenience items matter on a 4HU rack that lives behind a cubicle door: the Siemens 6AG4104-1AA02-1BX0​ puts 4× USB 2.0 on the front bezel (behind a lockable door) for quick USB-key OS patches, WinCC backup pulls, or dongle insertion (if the PCS 7 license is on a USB stick rather than the onboard SIMATIC PID). DVI-I supports both digital and VGA-adapted monitors—handy when the control room still runs VGA KVM matrix. The filtered 100–240 V AC supply includes a line filter and inrush limiter, and the chassis fan bank is thermostatically stepped, not full-speed-always, keeping the Siemens 6AG4104-1AA02-1BX0​ audible but not intrusive in a shared control room.
