Behavior on EtherCAT failure
With the following products you can define which switching state the outputs are to assume in the event of an EtherCAT failure:
- EP2038-0042
- EP2816-0003
- EP2816-0004
- EP2816-0008
- EP2816-0010
- EP2817-0008
- EP2839-0022
- EP2839-0042
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.
- EP2038-0042 and EP2839-00x2
You can set the "Safe state value" in the CoE parameters 80n00:05hex. Example for channel 1:
- EP281x
You can set the "Safe state value" in the CoE parameters 8001:0n and 8011:0n. Example for Output 1:
Deactivate
If you deactivate the function "Safe state", the respective channel retains after an EtherCAT failure the switching state it had before the communication failure.
In the factory setting, the function "Safe state" is activated for all outputs. You can deactivate them individually for each output.
- EP2038-0042 and EP2839-00x2
You can enable or disable the function in the CoE parameters 80n00:04hex "Safe state active". Example for channel 1:
- EP281x
You can enable or disable the function in the CoE parameters 8000:0n and 8010:0n. Example for Output 1:
