Need help, M-NET communication on APACS+ DCS MOORE.

On our compression station, we got a big problem with the M-NET communication. This problem is always appear during the starting of the new machine equipped Speedtronic Mark 6.

Always we have the ESD Station trip. The alarm is backup FAILED. We do not know how to do and how to find a solution.

Any one had the same problem on the APACS+ MOORE communications M-NET.

Actually the APACS+ DCS is owned by SIEMENS

Thanks
 
I presume the APACS is for the Anti Surge loop and the DCS is SIEMENS, can you please confirm you trip by ESD.

Regards,

Hi,

Does any of your ACM's or CCM's have a scan rate of >70%? Is it a combination of MNET and MBUS - are all the MBUS terminators fitted? Have you ran the MBUS/MNET analyzer software? Is the MNET locking to one side? You can check this on your MBX. Is should be 5 secs on A then 4 secs on B.

If still a problem you can contact me at,
