I/O Check

Based on the device view, wiring tests can be carried out for conventional, analog and digital inputs/outputs of a device, for example by setting output signals for test purposes (see also 8 Performing Device Diagnostics).

Note

Not all devices support testing of inputs and outputs

Please note that not all devices support testing of inputs and outputs. Only the device view with the status indicators is available for these devices.

The device hardware used is visually displayed in the upper area of the “I/O Check” view. The LED indicators on the left show the status of the head station and the LED indicators on the right show the status of the channels.

Head Station Status Indicators

The head station status indicators are always enabled. The LED indicators in the graphic are not clickable, but they do show the current status message of the head station on mouseover.

Note

Flash codes are not displayed in real frequency

Note that the flash codes are not displayed in real frequency.
Detailed descriptions of the diagnostic messages and flash codes can be found in the manual for the respective product.

Channel Status Indicators

The status indicators for the connected channels do not show the current status (read-only) of the digital inputs and outputs in permanent fashion, but only in monitor mode. Monitor mode is enabled if there is an online connection to the device.

Note

LED status refers to on/off status values related to digital I/O channels

For diagnostic channels, the physical LED indicators may consist of several status values. The LED status displayed here only refers to on/off status values directly related to digital I/O channels.

Clicking on the eye icon below the respective device displays tables with status values for the channels of the inputs and outputs used. The indicator can be switched between control and monitor mode.

Control	Description
	Zoom in Enlarges the device view by one level with each click.
	Zoom out Reduces the device view by one level with each click.
	Original size Shows the device view in its original size.
	Adjusts the size of the displayed areas The area between the device view and the tables with status values can be adjusted by moving the separator.
	Tables with status values hidden When you open the device view, the tables with status values for input/output channels are initially hidden. By clicking on the grayed-out eye icon, the tables below the device graphic are displayed.
	Tables with status values displayed Clicking the eye icon again hides the tables displayed for the status channels.
	Switches directly to the settings of the I/O channels Jumps to the “Settings” view > “I/O-Channels” tab and in the tab to the first configurable channel composition.
Control mode	Control mode enabled When control mode is enabled, the channels are unlocked for changes. Values can be written.
Control mode	Monitor mode enabled When control mode is disabled, the current status values are displayed (read access only).

The latency is also displayed, i.e., the update cycle (in s) of the displayed device values depending on the connection, device load or other factors:

Display	Description
Monitoring active	Low latency, high synchronization rate
Monitoring active	Higher latency, delayed synchronization rate
Connection unstable	High latency, unstable connection

Display/setting of status values

Status values can be shown as follows using selection fields:

as raw values or
as scaled values with units.

Scaled representations can only be set on the user interface; raw values are still used for communication.

Sliders can be used to set digital values:

Switch setting corresponds to 1 or true
Switch setting corresponds to 0 or false

Note

“I/O Check” view may not show original channel configuration

For devices that support variable channel configuration (e.g., WAGO Compact Controller 100, Item no. 751-9402/xxx-xxx), the assignment of the channels can be changed in the “Settings” > “I/O-Channels” view. The “I/O Check” view then shows the modified channels instead of the original ones.

Tip:
You can also access an overview of the LED indicators/status messages via the “Settings” > “LEDs” view.
In addition, each page has a “Device Status/Actions” section via 8 Settings.
