ctrlX PLC - EtherCat / Motion synchronous task

[AndreasL]

Hello,

In the MLC, there was a possiblility to define a task to run as EVENT_OP_MODE_MOTION_CYCLIC or EVENT_OP_MODE_SERCOS_CYCLIC or EVENT_OP_MODE_ETHERCAT_CYCLIC.

How do you do the same thing in ctrlX PLC?

The scheduler of the trlX CORE provides a predifined PLC trigger signal which will be synchronised to the ethercat.

This signal can be used as an external task trigger at the PLC engineering

Hello,

there is no callable under the 'plcEvent07'-task in my project. So i'm trying to add the callable 'plc-external-event' manually but the error 'DL_SUBMODULE_FAILURE' comes up. I tried to add it in every different state (Operation, Service, Setup).

Can you please help?

As it was only implemented for showing purposes the preset callable for an external event for the PLC will be gone and needs to be added by hand.

You have to choose the event number you like to use in the ctrlX CORE WebUI under "Settings --> Scheduler":

ctrlX CORE WebUI add external PLC event
