I get CNF errors on my ATV71 when controlled by M251MESE using EtherNet/IP

When ATV71 with EthernetIP card VW3A3316 is controlled by M241/251 by EtherNet/IP then it is mandatory to wait 40 seconds before sending a run order to ATV71.
The countdown of these 40 seconds should be started as soon as EipGetHealth returns “1” (means “Ethernet IP connection is OK”).
 
If a run order is sent too early then ATV71 reacts by tripping in CNF error (“communication network detected fault”). This error can be acknowledged by using bit 7 of control word (as any other resettable error).

VW3A3316 v1.2ie14
TM251 v4.0.5.11
