2 Description of Device Table 2-1 indicates which combinations of operating units and computing units can be delivered.
Description of Device 2.1 Operating units with key-based front panels The number of keys, their labeling and their functionality are identical on all operating units featuring key-based front panels. The various types of front panel differ only in the arrangement the keys and the size and type of display. Figure 2-1 shows the front view of the 12” version as an example to illustrate the status indicators, the different keypads, the USB interface, display and mouse.
Description of Device 2.1.2 Keyboard The keyboard is subdivided into different functional groups of keys: S function keys, soft keys S control keys S alpha keys S numeric keys S cursor keys Function keys, soft keys The function keys arranged on the left and right of the display and in two rows at the bottom of the display possess LEDs and can be assigned freely. ... Fig.
Description of Device Alpha keys The alpha keys are used to enter letters, special characters, spaces and underscores: Underscore Space Fig. 2-4 Switching between upper-case and lower-case letters Alpha keys In their basic assignment, the alpha keys are used to enter lower-case letters. To enter upper-case letters, press and hold down SHIFT (see Figure 2-3). The LED on the SHIFT key lights and you can then enter upper-case letters with the corresponding alpha keys.
Description of Device Entering special characters, arithmetic characters and signs Most of the numeric keys have also been assigned special characters, arithmetic characters or the plus sign. The special characters are identified in white, in the top left corner of the keys concerned. To enter the plus sign, the special character or the arithmetic character you require, press the FN control key (see Figure 2-3) and, in addition, the appropriate numeric key.
Description of Device 2.2 Operating units with touchscreen front panels The 12.1” version and the 15.1” version of the touchscreen front panels differ in their dimensions and the size of their displays. The 12.1” version does not have drill holes (covers) at the sides. Figure 2-7 shows the 15.1” version as an example to illustrate the status indicators, the USB interface and the display.
Description of Device 2.3 Interfaces The operating unit has interfaces on the front and rear sides. 2.3.1 Front-side USB interface On the front side of the panel (see Figures 2-1 and 2-7) there is a USB interface *) protected by a rubber cover. This can be used, for example, to connect an external keyboard or an external mouse.

Drill suitable holes around the prepared mounting cut-out (see Section 3.1) as specified for L4 and L5 in Figure 3-3. 2. Carefully knock out the drill hole covers on the front side of the opera- ting unit. 3. Fix the operating unit at the drill holes using suitable screws and nuts. 4. Continue as from step 3 for clamp fixing.
4 Maintenance 4.1 Spare parts and accessories 4.1.1 Spare parts The following are available as spare parts: S For the Panel PC in standard and remote mount form factor: the complete operating unit. It is not possible to quote a generally valid order number for the operating unit, since it depends on the current equipment configuration (operating unit plus computing unit) and its order number. You can obtain it from your Siemens office.
Maintenance 4.2 Detaching the operating unit in standard mount form factor from the computing unit It may at some stage become necessary to separate the operating unit from the computing unit, e.g. to replace the operating unit. 4.2.1 Panel PC 670 Swinging open the computing unit To swing the computing unit away from the operating unit, proceed as follows: 1. Undo the knurled screws which secure the computing unit to the rear side of the operating unit. 2.
Maintenance Removing the computing unit completely To remove the computing unit completely, continue as follows: 3. Remove the cable connectors K1 and K2 of the operating unit (see Fi- gure 4-2) from their corresponding counterparts on the computing unit. Two mounting rails are screwed to the computing unit. The two ends of these rails are formed as clips (see Figure 4-1). 4.
Maintenance 4.2.2 Panel PC 870 Removing the computing unit Proceed as follows: 1. Disconnect the power supply. 2. Swing open the mounting panel to obtain access to the rear of the PC 870. 3. Loosen the four (retained) knurled screws which secure the computing unit to the rear side of the operating unit (see also Figure 3–3). 4. Swing the computing unit away to the left, whereby the two left clips act as hinges and thus prevent an unintentional releasing of the computing unit.

Maintenance 4.3 Replacing soft key labeling (operating units with key-based front panels only) The two horizontal and two vertical rows of soft keys of the operating units with key-based front panels can be assigned user-specific functions. You can use two printed labeling strips to identify the soft keys. A4 foil sheets are available for you to prepare the strips for insertion. Procedure: 1. Print the foil with a laser printer. 2. Cut the labeling strips along the preprinted lines. 3.
Remote Mount Form Factor 5 This chapter describes the specific features of the Panel PC in a remote mount form factor to the extent that they vary from the standard mount form factor (described in Chapters 2 to 4). The present document centers around the operating unit. The part of the description referring to the remote mount form factor of the computing unit will be found in ”Panel PC 670 Computing Unit” and ”Panel PC 870 Computing Unit” manuals.
Remote Mount Form Factor 5.1 Overview 5.1.1 Configuration Figure 5-1 shows the components in a remote mount form factor: 1. The receiver and (optionally) a direct key module are mounted on a mounting plate that is screwed to the rear panel of the operating unit, instead of the computing unit. 2. The transmitter is fitted between the mounting rails beneath the computing unit. 3. The receiver and transmitter are interconnected by a cable up to 20 m long (refer to Section 5.3).
Remote Mount Form Factor 1. PC 670/870 operating units with receiver: – 12” remote – 12” touch, remote *) – 15” remote – 15” touch, remote *) *) Includes operating units without USB port on front panel 2.

Appendix B: ESD Guidelines B What does ESD mean? Virtually all present-day modules incorporate highly integrated MOS devices or components. Due to the technologies used, these electronic components are very sensitive to overvoltages and consequently therefore to electrostatic discharge: These devices are referred to in German as Elektrostatisch Gefährdeten Bauelemente/Baugruppen: EGB. The more frequent international designation is: ESD (Electrostatic Sensitive Device).
Appendix B: ESD Guidelines Handling ESD assemblies A general rule is that assemblies should be touched only when this cannot be avoided in the course of the work that has to performed on them. Under no circumstances should you touch device pins or circuitry when handling printed-circuit boards. You should touch devices only if S you are grounded by permanently wearing an ESD wrist strap or S you are wearing ESD shoes or ESD shoe-grounding protection straps in conjunction with an ESD floor.
