General

If a slave can´t be detected by a network scan or if it is not present in the Device Catalog, it´s commonly the case of not choosing the correct file type upon importing the ESI file in SyCon.net.

Please make sure to choose EtherCAT DFF whilst importing the salve´s description file:

Master


The LEDs on our master hardware have a wide variety of states to get a first hint of what might be the issue:


One of the most crucial parts and often the cause of issues is the cabeling / topology of the EtherCAT network. Our master firmware is really strict about proper topology.

For EtherCAT every slave has an IN and an OUT Port and the master has a Main and a redundancy port.

The cabeling should be done as follows:

The master´s Main port is connected to the first slave´s IN port and the OUT port of the first slave is connected to the IN port of the second slave and so on.

For this document a network with two slaves was chosen:



Before doing a Network Scan please unplug the cable used for cable redundancy (green). After loading the configuration to the EtherCAT master it can be plugged back in. For the current EtherCAT master Stack, cable redundancy is always activated and configured by default.

If you now do a network scan by right click on the cifx card → "Network Scan..." it will look like this:

The first slave is the Baumer Encoder and the second slave is the netTAP 151, as expected.


If you were to switch the IN and OUT connection on the Baumer Encoder a scan will look like:

If you pay close attention you will already see the mismatching topology now.

If this isn´t noticed or if the network is build incorrectly by hand the error: 0xC0CD0043 "Topology error detected" will be shown in the general diagnosis:

To determine the difference between the configured and the real topology use the Diagnosis and do a "Online Comparison". This will also show, if all the device descriptions used match the real hardware, according to the parameters: Vendor ID, product code and Revision.


Slave

As for the Master the Slave Stack will also show it´s current state via the LEDs:
