4 IO Test

The IO Test task serves to check the wiring of an IO device even without a programmed CPU, and to protocol the test results in a quick, error-free and simple manner.

4.2 IO Test Mode

In IO Test mode, the screen consists of two main views:

"Device View" (1), a graphical representation of the tested device

The "Details" table (2) which shows you additional information about the tested device and the test in general. The parameters are loaded from GSDML file.

Function Bar

The following function is available in the function bar:

Icon	Name	Function
	Force and Monitor Values	Activates and deactivates control of the device through PRONETA Basic for the IO Test.

WARNING

Manipulating the interfaces on control components can result in sudden movement of the machinery and the electrification of equipment.

Physical injury and electrical shock to personnel are consequently possible.

Make sure the machinery is in a safe state with no unauthorized personnel within range, before activating the IO Test.

NOTICE

Loss of F-destination addresses

After performing an IO test with PRONETA Basic on a device, the attached F-IO modules will have their F-destination addresses deleted, leading to the module entering a safe state.

In this case, assign the F-destination addresses once again to the F-modules concerned using the respective engineering tool.

Testing of F-IO modules is disabled by default.

NOTE

To perform an IO Test on distributed IO modules, PRONETA Basic establishes a PROFINET application relation (AR) with the target device. Make sure that no other PROFINET controller occupies this connection.

The state of the IO Test is indicated by the color of the "Device View" and "Details" table header bars:

Light green indicates the IO Test is active. In addition, the words "Force Mode" appear at the right of the bars.

Dark petrol indicates the IO Test is inactive.

Device View

Usage

The device view shows a symbolic representation of the device you selected for the IO Test mode. The status and IO LEDs are updated in real time to reflect the actual state of the physical device.

To get a larger view of any module click the "+" symbol (1) above the module. A small Popup Window will appear.

Clicking on any of the modules here will show the module’s parameter table in the "Details" view, or highlight the corresponding section, depending on the tab chosen.

Modules with information in their diagnostics buffer are displayed with a red header.

Digital IO

Click on any LED symbol of an output module to toggle the status of the corresponding output. Likewise, voltage applied to any input will light up the corresponding input module LED.

To force digital values, you can also use the "Test Results" tab in the Details View .

Analog IO

Read analog values from input and output modules in the same fashion.

To force analog values, use either the Popup Window or the "Test Results" tab in the Details View.

NOTE

Optional plugged connection terminals (3DI/LC modules) of Motor Starter units will only be shown after Force Mode has been activated.

Popup Window (IO Test)

Usage

Above each device module in the Device View, a "+" symbol allows you to open a popup window with a larger symbolic view of the module’s inputs and outputs. If you open multiple modules, their popups will be arranged in a row within a single window.

Click the close icon "´" in the top right of the popup window segment, or the "-" symbol above the module in the device view, to close the popup for this module again. To close the whole window click the close icon "´" in the top right of the window. To rearrange the modules within the popup window, click the table header of the module in question and drag it to the desired position.

Digital IO

Digital inputs and outputs can be monitored and forced, by displaying or checking and unchecking the fields corresponding to their connections. Green fields indicate active lines.

Analog IO

For analog modules, symbolic channel names can be entered in the fields next to the channel numbers displayed. These will automatically be copied into the test protocol.

Analog output values can be forced by either entering the numeric value in the corresponding field, or by dragging the slider across the slider bar below. Clicking the symbol next to the field will reset the output to the default value.

Details Table

The Details Table consists of four tabs, each with its own function bar:

Parameters to set the module parameters

Test Results to perform and protocol the wiring test for the device

IO Event Log to monitor regular events like changing module input and output values

Diagnostics to record irregular system events like plugging aud unplugging of modules.

Parameters

This tab gives an overview of the parameter set of the module selected in the device view. Parameters can be only edited while "Force and Monitor Values" is not in operation (see IO Test Mode, "Function Bar" section).

The parameter set can be stored to a file on disk, loaded from a file, and copied and pasted from the windows clipboard to transfer the parameters to a different module.

Function Bar

The following functions are available in the function bar:

Icon	Name	Function
	Save Parameters	Saves the current parameter set of the whole device to disk.
	Load Parameters	Loads a previously saved parameter set from disk and assigns it to the current device.
	Copy Parameters	Copies the parameter set of the currently selected module to the Windows clipboard.
	Paste Parameters	Pastes a previously copied module parameter set from the Windows clipboard to the currently selected module. The icon is grayed if the parameter set in the clipboard does not fit the selected module.

The commands "Save Parameters" and "Load Parameters" transfer parameter sets between devices and are useful to configure a number of identical devices. In contrast, "Copy Parameters" and "Paste Parameters" are used predominantly to "clone" module configurations within one device.

Test Results

This tab offers the functionality for the actual IO Test of the currently selected device.

The test table is vertically divided into sections according to the IO modules present. Each section can be collapsed and expanded again by clicking on the triangle symbol "▼" in the section header.

The test table consists of the following columns:

"Channel": The name of the IO channel as determined by the device.

"Control": Forcing status of the selected output.

Click on the icons to toggle the status of digital outputs, or drag or enter manually the value for analog outputs. Values entered will be immediately forwarded to the hardware. (For inputs, this field is grayed out and read-only.)
Alternatively, you can also change values by clicking on the LED representations of the device view, or by manipulating them in the popup window.
This column is only visible while the Force Mode is active.

"Symbolic Name": Arbitrary name, assigned by the tester to the channel. (See note below.)

"Address": Arbitrary memory address to which the IO is mapped. (See note below.)

"Status Wiring": The actual results as established by the IO Test are entered here by the tester. Select one of:

"N.a.": "Not applicable", not tested yet (default)
"OK": Test result OK, wiring in order
"Error": Test result not OK, faulty wiring

"Comment": Any additional information you want to add to the test.

NOTE

The values for "Symbolic Name" and "Address" serve only as memory aids for the tester.

The IO Test can be suspended and resumed at a later point in time by saving and loading the protocol.

After completion of the test, the protocol can be stored to document the proper wiring of the device. (See the Function Bar for details.)

Function Bar

The following functions are available in the function bar:

Icon	Name	Function
	Save Protocol	Stores the results of the current IO Test to disk (format: CSV), either when the test is completed, or when the test is interrupted.
	Load Protocol	Loads test results of an earlier IO Test from disk to proceed with testing.
	Reset Test Protocol	Discards the results of the current test and allows you to start over again. All results will be deleted from PRONETA Basic.
	Import Symbolic Names from an AML file	Imports symbolic names for device /IOs from an AML file (see Using an AML File as Reference.)

Using an AML File as Reference

An AML file can be used to provide symbolic names for IOs.

The following features of the device to be tested must match the name of the device in the AML file:

Device name

Module types

Module positions

If this is the case and the AML file contains symbolic names for the IOs, then the names from the AML file will be used for the IOs in the tested device, and shown in the column "Symbolic Name".

NOTE

This feature is currently not available for CPUs.

IO Event Log

This tab records a log of all regular events (like changes of the values of inputs and outputs) which occurred while the IO Test was active.

Clicking on a column header will sort the table accordingly.

Function Bar

The following functions are available in the function bar:

Icon	Name	Function
	Save IO Event Log	Stores the event log to disc (format: CSV).
	Reset IO Event Log	Clears all entries from the current event log.

Diagnostics

The table in this tab shows a record of all irregular events which occurred to the device while the IO Test was active, like the unplugging of modules or a signal wire break.

If the diagnostics buffer contains events pertaining to a module, the corresponding module header in the Device Table will be displayed red.

Clicking on a column header of the table will sort the table accordingly.

Selecting a table entry will highlight the corresponding module in the Device View. Similarly, selecting a module in the Device View will highlight the first entry concerning the module in the table.

The table consists of the following columns:

"Slot"

"Module"

"Channel"

"Symbolic Name" (as entered in the "Test Results" tab)

"Description"

"Details"

"Time Stamp"
