Softkeys

Operation

The capacitive keys respond quickly and directly. In order to prevent accidental operation, the

following measures must be applied:

● When the key is pressed a second time, the function is revoked

● Keyboard lock, e.g. when cleaning the keys/keyboard:

- Press the menu back key for longer than 5 seconds to activate it

- The associated LED flashes while the key lock is active

- Deactivate the keyboard lock by pressing again (> 5 s)

● Traversing motion that is initiated using direct keys must be additionally interlocked: For

example, using an acknowledgment button that is appropriately linked in the PLC

Note

Please observe the valid C standards for the particular machine type (e.g. for lathes: EN

ISO 23125-2010, pages 36+49). This states that a button that initiates motion with the

protective door open must be implemented using an additional acknowledgment device;

this is because for single-channel keyboards - such as the OP 019 - generally no PL

(performance level) level "d" can be achieved.

Special situations:

●

2 keys can be simultaneously pressed.

● The keys can also be actuated when operators are wearing gloves. However, especially

thick, protective gloves can restrict operation or even prohibit it.

LED displays

All keys with LEDs flash green:

● As long as the operating system has not started while booting.

● If communication to the PCU/TCU has failed and this state lasts for more than 5 s.

Remedy: Re-install the standard keyboard driver.

12.2.4

Screen saver

If a screen with high contrast is displayed unchanged for longer than an hour, then the

screensaver must be activated in order to protect the TFT display against so-called "burning

in" of the last displayed screen.

The time can be adapted individually. Further information can be found at:

Operation

The operator panel front is operated through finger contact with the touch-sensitive glass user

interface:

● Depending on the application-specific functions displayed in the display area, for example,

by:

- Gestures with up to 5 fingers

Note

Notes regarding operation of the touch-sensitive glass surface with multi-finger operation

function using gestures.

Observe the following notes in order to avoid incorrect operation of the touch-sensitive glass

surface with multi-finger operation function. Otherwise, entries made at the device will either

be incorrectly identified/implemented - or not at all.

● The OP 019 black does not support safety-relevant functions and these may also not be

implemented in the touch-sensitive glass user interface.

● The touch-sensitive glass user interface reacts to contact with its surface, not to pressure.

Therefore, do not subsequently attach a protective film to the touch-sensitive glass user

interface. Also remove all protection and packaging foils, as these have a negative impact/

prevent data from being entered and initiate incorrect operator entries.

● Only operate the touch-sensitive glass user interface with your finger tips, not with your

fingernails.

● Touch the touch-sensitive glass user interface either perpendicularly or at a maximum angle

of 45° to the surface.

● Avoid unintentional multiple touches, e.g. with the knuckles or by leaning on or against the

display.

● Make sure that the surface of the touch-sensitive glass screen does not get dirty. Cleaning

information can be found on the Internet in the following article in the Service & Support

portal of Siemens Industry:

http://support.automation.siemens.com/WW/view/en/39718397.

Always check whether the executed operator actions were recognized by the device.

Note

Please observe the valid C standards for the particular machine type (e.g. for turning machines:

EN ISO 23125-2010, pages 36 and 49). These state that a button that initiates motion with the

protective door open must be implemented using an additional acknowledgment device; this

is because for single-channel keyboards - such as the OP 019 black - generally no PL

(performance level) "d" can be achieved.

Displaying the TCU menu

To display the TCU menu, simultaneously touch the left-hand and right-hand lower corner of

the active display area in order to display the TCU menu.

Direct control key module

14.1

Description

The task of the direct key module is to directly transfer the operating signals for the two rows

of keys on the sides of an operator panel front to the control (PLC) without diversion through

intermediate firmware. The signal-to-key assignments are shown in the table and figure in

Section: "Interfaces" → "Operator panel front."

The DKM can be combined with operator panel fronts OP 012, OP 015A and TP 015A.

The DKM converts the key signals to the PROFIBUS DP protocol by means of the ASIC LSPM2

(EN 50170-2, 12 MBaud).

Power is supplied via the operator panel front. The PROFIBUS is completely isolated from the

DKM / operator panel front by means of an opto-coupler and DC/DC converter.

The DKM is operated as a slave on PROFIBUS. The address can be set between 1 and 99

using rotary switches. Two bytes of data are transferred.

In the control, the keys are handled as if they were 16 ordinary digital inputs.

● When the device is switched on, a HW self-test of the service module is first carried out;

Code 88 is output in the process.

● While the BIOS boots, the PCU base software runs through a self test, where the codes of

the corresponding test step are displayed. Code 00 is displayed if booting is completed

without any error. The code of the most recently started test step is displayed when an error

occurs. See BIOS beep codes (Page 258).

● Display of the service switch positions.

● Codes of applications can also be displayed if required.

LEDs H1 and H2

● While the BIOS boots, the two LEDs light up in two colors (red and green) in order to test

their operation. The two LEDs switch off when booting is completed without errors.

● Applications can control the two LEDs if required.

The diagnostics displays display the following information:

● The diagnostics display "H1" displays status codes of the PCU-Basesoftware.

● The diagnostics display "H2" is assigned to the application software.

The meaning of the displayed status codes depends on whether the PCU 50.5 is in system

startup (Page 261) mode, running mode (Page 262), or shutdown (Page 262) mode.

Service

Restore the default values automatically at the next boot (e.g. with BIOS

update or SSD replacement).

Service

After a restart, booting is preferably from another storage medium (e.g.

USB flash drive) as from the installed SSD.

The PCU base software is capable of reading out the switch positions if this was set beforehand

in the BIOS setup. The default setting is "evaluate (Operation mode switch -> Enabled)".

Power button

The power button is located below the diagnostics display; it can be used to start up and shut

down the Windows operating system. This means that the power button is an alternative to

the on/off switch.

Exclusive interrupts in the PIC mode

The system BIOS is set when delivered so that for the system start, the interrupts are

automatically assigned to the slots.

Depending on the system expansion, it is therefore possible that the same interrupt is assigned

to several slots. In this case this is called interrupt sharing. No exclusive interrupts are available

in the PIC mode. You must disable system resources in order to obtain exclusive interrupts. It

cannot be predicted which PIC interrupts will be assigned by BIOS at the next start.

Mounting

15.4.1

Preparation for mounting

Mounting of the PCU 50.5 depends on how it is going to be used. A distinction is made between

the following types of mounting:

1. Standard mounting: Operator panel on the machine

- for assembly of PCU and operator panel front

2. Flat mounting: In the control cabinet

- for PCU flat on the control cabinet rear wall

3. Book mounting: In the control cabinet

- for PCU at an angle of 90° to the control cabinet rear wall

You require a suitable set of mounting brackets for each mounting method. You can find the

corresponding article number in Section "Accessories".

Note

First, screw the appropriate mounting brackets onto the PCU before you mount the PCU on

an operator panel front.

NOTICE

Damage to the mainboard

For installing the mounting brackets for the upright installation, use only M4x10 screws. For

all remaining mounting brackets, use M3x8 and M4x8, (provided).

The mainboard will be damaged if you

screw in the M3x8 and M4x8 screws without mounting brackets,

- or if you use other 8 mm screws (without a flat washer or tension ring) or

- longer screws,

- use the M4x10 screws for mounting the brackets on the PCU 50 (previous model).

Image 15-12 PCU 50.5 with mounting brackets (standard mounting)

Mounting the PCU 50.5 with an operator panel front depends on the size of the operator panel

front:

● When mounting a PCU 50.5 and operator panel fronts with screen diagonals ≤ 15 inch,

refer to Chapter: “OP 012,” section: "Mounting" → "Assembling OP 012 and PCU."

● Mounting a PCU 50.5 with an operator panel front OP 019 is described in Chapter: “OP

019,” Section: "Mounting" → "Assembling OP 019 and PCU 50.5".

Connecting Ethernet/USB strain relief

The Ethernet/USB strain relief supplied in the product package is used to prevent accidental

removal of the Ethernet cable and Industrial Ethernet FastConnect connector from the device.

You need two cable ties to use the strain relief. In addition to the Ethernet cables, you can also

use this strain relief to protect the four USB cables from inadvertent removal.

Preconditions

● Take the strain relief ①, the cable tie ② and the two screws (M3) from the accessories

pack provided.

● To secure the strain relief, you will need a TORX T10 screwdriver.

Power supply

The PCU 50.5 is supplied with 24 V DC.

Preconditions

WARNING

Impermissible cable cross-sections can damage the PCU

The cable cross-section must be adapted to the short-circuit current of the 24 V DC power

source so that no damage is caused by the cables if a short-circuit occurs.

Only cables with a cross-section of at least 1.3 mm² (AWG16) and maximum 3.3 mm²

(AWG12) may be connected.

Note

The 24 V DC power source must be adapted to the input data of the PCU (see Calculating the

power (Page 264)).

Ensure that the PCU's On/Off switch is in the '0' (Off) position to prevent unintentional startup

of the device when connecting it to the power supply.

3. Fasten the cable with the supplied line con-

nector interlock, if necessary.

Note

Reverse polarity protection

The DC power supply (24 V; -15% / +20%) has a mechanism to protect against reverse polarity.

The unit is not damaged if the cables and ground are connected, interchanged. The unit does

not switch on. After the power supply has been connected correctly, the unit will again be ready

to operate.

15.5.2

Equipotential

A low-impedance ground connection ensures that interference signals generated by external

power supply cables, signal cables or cables to the I/O modules are safely discharged to

ground.

The equipotential bonding terminal ① on the device (large surface, large-area contact) must

be connected with the central grounding point of the cabinet or plant in which the PCU is to

Units based on USB

You can connect or disconnect devices based on USB (USB 1.1 Full Speed or 2.0 Hi-Speed)

during PCU operation if this is supported by the operating system (e.g. Windows XP).

Note

If you are using commercially available USB devices, the interference immunity of the entire

system can be reduced. The end user takes responsibility for the use of such devices.

Information on which connection cable is required and how to adapt and set the interface can

be found in the User's Manual for your I/O device.
