Title: Peerlink Errors
Post by: PLCwannabe on October 07, 2021, 10:32:48 AM

I have one plc showing an error on PL0-15, while multiple other plcs on the same network do not show any errors with peerlink. How is that possible?

The red circle with a slash through it simply means you have more than one device on your network publishing (via PEERLINK instruction) to this block (Block 0; PL0-15). It could be that this particular PLC is the only one that "sees" the duplicate publication? Regardless, make sure only one PLC is publishing to Block 0.
