Hi Everyone,

We are facing communication issues on LC and GC instruments for past 6 months.

Agilent OpenLAB instruments and we are still unable to find the root cause. can some one suggest a solution for this.

Regards,
K. Jagan
Hello

More details please...how can we help you if we don't know what kind of problem you have - "communication issue" is kind of broad term. Isn't it?

Regards

Tomasz Kubowicz
Hi,

When users login and run sample sequences on instruments. The sequence suddenly gets aborted and displays communication issue in the instrument log.

Sudden termination of sequence and displays communication error in the log.



We have investigated in the below possible ways.

CPU performance of the AIC server - Was less than 50%
Network fluctuations between instrument and AIC server - Everything was normal.
Only few instruments have this issue on a particular site.
Please find below the completed error log.

Hello

You've got ECM so first thing I'd do is to bypass network and run few sequences as standalone system : PC - LC (no network ECM).
Then you can narrow it down to network issue (if you'll have no errors without ECM).
I'd also run online connection window (you can do it through CMD window) in background so you can monitor PC-LC connection all the time. If you have some network issue (IT can do it some upgrades in the night) you will see connection lost.

Tomasz Kubowicz
Hi Thomas,

Thank you for your response.

This is Production system and we cannot stop the ECM as many instruments are simultaneously connected to the AIC server

For the below suggestion can you help me get more idea on this.
I'd also run online connection window (you can do it through CMD window) in background so you can monitor PC-LC connection all the time.

Hi

You need to know IP of LAN card in LC (detector) - you can check it in "instrument configuration" in OpenLab

In CMD window type: ping "IP adress" -t

you will see connection status berween PC-LC

Regards

Tomasz Kubowicz
Hi Tomasz,


We have tested the IP address of LAN and monitored it several times during the sequence run where we did not find any issues.

Actually almost all teams from site level network, switch ports and everything were monitored and we were unable to find a solution.


This occurs in a set of instruments alone. I can send you all the investigations done to your email ID if you can share.

Even Agilent engineers are unable to find the root cause.

Regards,
K. Jagan
I have had mysterious corrupted sequences before. I started from scratch to create a new sequence and save it.
Hi Jagan,

We are experiencing the same problem with OpenLAB server in the past weeks. Have you solved the problem or have any idea about it? Thanks very much for any info.

Best,
Kan

It's my fault.

Ask my old boss. Whatever went wrong with Open Lab he declared that it was my fault. Interesting, because I'm a computer-idiot, can barely type, and just 3 weeks ago bought my first laptop (refurbished) and moved to Windows 7 from XP.
