EtherNet/IP: Termination of the connection with an Omron controller (corrected from V01.08.00)

Corrected from:
Servo-Inverter i950 FW: from V01.08.00
 
Response of the new version:
The cause of the described functional restriction has been eliminated.
Operation under an Omron control is now possible.

 
What happens?
The TCP connection via EtherNet/IP is incorrectly closed by the i950 approx. 0.5s after the connection is established. As a result, all included CIP connections (including the I/O connection) are terminated.

When does the behaviour occur?
  • Using an Omron controller (CJ2M) as an EtherNet/IP scanner

Which products are affected?
Servo-Inverter i950 FW, only V01.06.xx to V01.07.xx
 
Short-term measures / Evaluation / recommendations:
Workaround: Use the previous i950 FW: V01.05.00
It should be noted with the FW version that the EtherNet/IP function is incompatible with the successor versions from i950 FW V01.06.xx and thus a re-engineering of the scanner is necessary with a FW update of the i950.
