iec870 driver in redundancy Ed.2: test-frames (TESTFR) are causing delays 20-30s in the switch (STARTDT) to alternative IP

Summary

IEC870 driver - Issues with edition 2.0 redundancy. Delayed manual redundancy switch when the active connection was broken.

Description

IEC870 driver - Issues with edition 2.0 redundancy. Delayed manual redundancy switch when the active connection was broken.

Information

there is no workaround as if you configure the driver to use long T3, this will delay the detection of communication loss and it still may happen anyway that the T3 period meets the moment of switching.
