Portal view

The portal view provides a task-oriented view of the installed tools. The portals for the various

tasks (1) are located on the left side of the window. The actions for the selected window range

are adjacent window range (2). The objects processed with the selected action are displayed in

the central part of the window range (3). If necessary, switch to the project view to edit the

selected object. From the portal view, navigate to the project view via the "Project view" (4) link

on the bottom left of the screen.

System Description

Project view

The project view provides an object-oriented view with several windows whose contents

change depending on the executed action. The working area (2) with the device to be

configured is in the central window range in the device configuration. You use the work window

to configure the hardware of the automation system, create the user program, or configure the

process images. The rack with the modules that have already been positioned is displayed in

the device view (1). Another window – the inspection window (4) – displays the properties of

the object selected in the work window. The task window (Task Card) (3) provides support

with the available modules via the hardware catalog. Certain content of an object selected in

the overview window or in project navigation is displayed in the detailed view (5).

The figures below show the project view windows in a sample project. Different window

contents are displayed depending on the type of editor used.

2.2 Safety Function and Safe State

Safety Function

The PXV100A* series device determines safe X position values for linear, guided

applications.

The PGV100A* series device determines safe X position values for automated guided

vehicles (AGV).

The position values for all device variants are determined using the stationary Data Matrix code

tape attached to the plant.

The safety-related customer application checks the plausibility of the received values against

expected values.

Note!

Note the Type of Code Tape!

The positioning system only works if the reader is used together with the 2-colored Data Matrix

code tape of the following type: PXV*-AA25-*.

The use of other code tapes is not permitted!

Configuration Instructions for PXV100A / PGV100A

System Description

2019-07

The plant designer assigns appropriate values when setting up the plant. After attaching the

Data Matrix code tape, the plant designer determines the corresponding expected values at the

positions relevant for the application. The values determined in this way are incorporated into

the safety-related application and then their plausibility can be assessed during the operation

of the plant using the data from the sensor. Depending on the result, the application responds

to ensure the safe operation of the plant.

For the safety function, the reader provides the following safety-related data:

The reader provides you with the following non-safety-related data:

The valid bit in safe status reflects the state of the safe position data. For processing of the

position data in the application, the state of the valid bit must be evaluated in terms of safety.

Depending on the state of the valid bit, the plant control software performs further processing.

The corresponding actions are triggered, to continue to ensure the safe state of the plant. The

response to the respective state is determined by the application and can only be displayed

here by way of example.

Valid bit = "logic 1": a valid position value is delivered in the safe X position data. This can be

used for further processing in the safety-related plant control software, where it is checked

against the expected values of the application for plausibility. The application responds,

depending on the result.

Valid bit = "logic 0": The device is unable to determine a position at this time. The content of the

safe X position data is "0." This state can be triggered by the following scenarios:

■Data Matrix code tape is missing

■Data Matrix code tape is not readable

■Reader is outside the sensing range

■Lens is dirty

■Reader is in the initialization phase

It is the task of the plant control software of the respective customer to evaluate and check the

plausibility of this state in each case. The result of this evaluation and the application determine

the steps necessary to ensure the safety of the plant.

When planning and setting up the plant control software, the evaluation of the valid bit must be

considered and incorporated in terms of safety.

The described state is not to be confused with the safe state of the positioning device.

Configuration Instructions for PXV100A / PGV100A

System Description

Additional requirements, which are described below, apply to the safe state of the positioning

device.

Safe State

The safe state of the reader means that it interrupts the PROFIsafe communication in defined

fault cases. If the reader switches to the safe state, PROFIsafe data is no longer transferred to

the control panel.

Fault cases that result in the safe state.

If the PROFIsafe connection from the reader to the control panel is interrupted, this generates a

communication error according to the PROFIsafe standard, which the plant designer must deal

with appropriately. After the reader is restarted, it goes back to the initialization phase (INIT). If

another error triggers the safe state again within 90 s, the startup lock is activated. See the

section "System startup lock in the case of a fault."

In this case, contact Pepperl+Fuchs support.

Reaction time

The reaction time for the safety function is 165 ms.

The reaction time does not include the PROFIsafe watchdog time.

System Startup Lock in the Case of a Fault

The positioning system has an internal error counter for the safe state. This is increased when

the safe state occurs. If the safe state is triggered twice within 90 seconds, a startup lock is

activated in the system. As a result, the safety-relevant part is no longer started, and

PROFIsafe communication can therefore no longer be established.

The user can identify this state by means of the disabled illumination unit. The non-safe

PROFINET communication part remains available. The camera is thus disabled. The

positioning system must be restarted (power reset) to exit this state. The counter is cleared 90

seconds after the positioning system is started, provided that no safety-critical errors occur

during this period, or upon the successful establishment of PROFIsafe communication.

The following errors result in the safe state:

■Internal safety system errors

■Device-specific errors (0x48) and suberrors (see original instructions)

■Abortion or termination of the PROFIsafe connection
