About us
At a Glance
The debug screen can only be accessed in online mode. It can be used to display bus, slave and CANopen master operation.
Illustration
The figure below is extracted from the debug screen for our example.
Description
The table below shows the different zones of the debug screen:
Number
Element
Function
1
CANopen Slaves state
This zone displays all the slaves (also called nodes) on the CANopen bus. A faulty slave is displayed in red, when the fault disappears, it is displayed in blue. If there is no fault, it is displayed in black. Selecting a slave updates zones 2, 4, 5 and 6.
Act.: indicates whether the slave was activated in the Sycon configuration (1=activated, 0=deactivated)
Life T.: Life Time.
In our example, we display two slaves (or two nodes); these are the two nodes of our Sycon configuration.
Note: When a node is displayed in red, you can obtain the causes of the error by clicking on it. The information line is automatically updated with diagnostic information.

Inputs
When a slave is selected, this zone contains the list of words, which are associated with it on input.
A clearer explanation is given with the display of the CANopen topological address (%IW\3.2\0.0.0.0) and reserved memory area in the PLC (%MW0).
If node 2 is selected, then the previous illustration is displayed; if node 3 is selected, the screen changes and displays the %IW of node 3.
3
Output value
When an output word in zone 4 is selected, its value can be modified by entering a new value then clicking on the OK button.
4
Outputs
When a slave is selected, this zone contains the list of words that are associated with it on output.
A clearer explanation is given with the display of the CANopen topological address (%QW\3.2\0.0.0.0) and reserved memory area in the PLC (%MW50).
If node 2 is selected, then the previous illustration is displayed; if node 3 is selected, the screen changes and displays the %QW of node 3.

Information on
When a slave is selected (click in zone 1), this zone contains its last diagnostic message, and to obtain information on the TSX CPP 110 card, simply click on the table header.

Request to send
This zone is used to send an SDO request. Parameter syntax is identical to that used to transfer SDOs using READ_VAR and WRITE_VAR requests. Pressing the Enter Request button makes the request input fields appear.
