Behavior on EtherCAT failure

You can define which switching state an output is to assume in the event of an EtherCAT failure. However, this only affects outputs that you have configured for switching, see chapter Switching outputs.

Functioning

If the EtherCAT state is not OP , the box switches all digital outputs to the switching state "Safe state value".
This does not only happen in case of an EtherCAT failure, but also in the following cases, for example:

• EtherCAT start-up phase, e.g. shortly after switching on the supply voltage
• Manual change of the EtherCAT status by the EtherCAT master

Configure

In the factory setting the "Safe state value" of all outputs is the value FALSE. The outputs are therefore switched off if the EtherCAT communication fails.

You can set the value for each output individually in the CoE parameters 80n00:05_hex "Safe state value".

Deactivate

If you deactivate the function "Safe state", the respective channel retains the switching state it had before the communication failure after an EtherCAT failure

In the factory setting, the function "Safe state" is activated for all outputs. You can deactivate them individually for each output. To do this, set the CoE parameter 80n00:04_hex "Safe state active" to FALSE.
