Both versions of the SIMATIC PCS 7 OS Client 427D are designed for maintenance-free 24/7 operation without the support of a fan.

The absence of rotating storage media means that the SSD version is particularly resistant to vibration and shock. When operating in a restricted access location (RAL), e.g. in a lockable control cabinet, operating temperatures from 0 °C to +50 °C are permissible for this version in a horizontal mounting position.

The compact design of the SIMATIC PCS 7 OS Client 427D (HDD/SSD) and the flexible mounting options (DIN rail, wall or portrait mounting) in a horizontal or vertical orientation help to achieve a space-saving design.

Expansions/interfaces

The SIMATIC PCS 7 OS Client 427D (HDD/SSD) has:

• 4 USB 3.0 ports (max. 2 high-current ports can be used simultaneously)
• 1 COM1 port (RS 232)
• 1 DVI-I port (combined DVI/VGA)
• 1 display port (DVI with DPP-to-DVI adapter); can be used for multi-monitor operation with two monitors
• 2 Ethernet interfaces 10/100/1000 Mbps (RJ45)

The two integrated Ethernet interfaces have a teaming capability and are thus suitable for connection to a redundant terminal bus (for details on implementation, refer to the function manual "Fault-tolerant process control systems", Section "Redundant, fault-tolerant terminal bus").

The SIMATIC PCS 7 OS Client 427D (HDD/SSD) is supplied without input/output devices. In addition to mouse and keyboard, two other input/output devices can be externally connected via the provided USB ports, e.g. an optical drive (DVD-ROM/DVD±RW) or smart card reader.

A process monitor with analog (VGA) or digital (DVI) connection can be operated at the DVI-I port. The adapter cable required for the analog VGA connection can be ordered as an option.

You can use the display port as a second graphics interface to implement multi-monitor mode with two process monitors. The first monitor in this case is operated on the DVI-I interface, the second on the display port (directly or via a DPP-to-DVI adapter).

The following resolutions are possible in multi-monitor mode:

• 1024 ? 768
• 1152 ? 864
• 1280 ? 1024
• 1600 ? 1200
• 1680 ? 1050
• 1920 ? 1080
• 1920 ? 1200

Monitoring functions

Configurable monitoring functions can be recorded and evaluated via SIMATIC IPC DiagMonitor and SIMATIC PCS 7 Maintenance Station. These monitoring functions include:

• Program execution (watchdog)
• Processor and board temperatures
• Enhanced diagnostics/messages, e.g. operating hours counter, hard disk status or system status, backup battery status

The "Power" and "Watchdog" signals are displayed on LEDs.
