Hi jds,

The problem is that the SegmentSize is 0, so you should set RedcomSegmentSize in SecondaryNode in the NodeConfig object (Prd1-ubuntu.SecondaryNode.RedcomSegmentSize in the directory volume) to 8192.

Hello Claes,

that worked already a lot better :) Now my master runs and sees the secondairy. When I stop the master, the secondairy becomes active, but ... I can see the master transmitting packets and the transmit count is going up, but the receive count stays 0 and nothing is received by the secondairy. There must be a second setting that isn't right I suppose.

Hi jds,

Check that the secondary node has cached the segment size and that SegmentSize in the RecomConfig.Link[0].SegmentSize is 8192.

This is how it should look in the passive node.

Claes,
in primairy as in secundairy node the link section is empty.
I'm starting to doubt about the section hierachies, is it correct that the planthier is linked in here?

The Link attribute is an array and you open it with Shift + Arrow Right. The first element contains info for the link.

Hierarchies should contain the hierarchies that are controlled by the plc thread, In your case, as you only have one thread, all hierarchies, so that is correct.

ok my fault, they both have a segmentsize of 8192 bytes. I can see the Racksequencenumber counting up @ the slave but not at the master. In the master I see the Lackseqnr counting up, but not as fluent, it's counting up in batches.

primairy


secundairy
