Posted 1 Jul 2021 I have two PF527 devices in a bus. These are in the same motion group. If I take the ethernet cable off, it will not connect the PF527 anymore back to the be controlled. I can find it on the net (ping is OK) and it is not showing any fault. In the PF527, there is reading 'connecting' and in the Studio5000 axis is showing 'Synchronizing'. Any resetting from the PLC does not affect to the situation. Also taking power off and on from the PF527 does not help. Only way is that I switch off the power from the PLC and after that it will be fine. I would like to understand, what is happening at this moment when it is synchronizing and why it is not successful? Is there any other way to get PF527 back to normal state than the PLC power off / on? Share this post Link to post Share on other sites

Have you tried the I/O tree and Disable the PF527 and Reenable? If that works there are SSV commands that can be crafted for the Logic to disable/enable the PF527.
