Im doing connection from S20-DI-64/1 to ctrlX drive by using EtherCat coupler.
In the ctrlX I/O Engineering I can scan and see my I/O module. But, when I transfer to field bus configuration then the state of EtherCat master in ctrlX work only show the "Pre-OP" state. Please see my attached picture below. If you have any experence to solve this issue please share with me.
P/S: The light "D" in S20-DI-64/1 module is still red flashing.
Solved! Go to Solution.
In your scan dialogue it looks like you only have connected to the EtherCat master the bus coupler but no IOs to it. Or they are not recognized.
Could you check the online status in ctrlX IO Engineering and also the status lights at the IO module?
It didnt recognize the I/O module actually, in the I/O module the "D" led was flashing. I have to add sub-module manually.
So as long as there is a difference between actually working and configured topology the bus cannot boot up to OP. So could you get it to run?
I agree in the documentation is mentioned that flashing red means "The device is ready for operation but there is no connection to the
previously existing device". Please check back plane bus, if pins are bent/broken.
which version of ctrlX Works / IO Engineering are you using?
Which version of ESI of S20-EC-BK does you use? You can find on the information tab.
