Ultramat 23 is not transmitting data to PLC

Hi,

We have GE 6FA Gas Turbines which use the following analyzer for CEMS monitoring.

The analyzer sends data to PLC which transmits on DCS. On one of our units, the said analyzer has been in service since 2010 however recently during normal operation of Gas turbine, the reading of same analyzer disappeared from the DCS HMI and hence there is no remote monitoring. CEMS reading is now available on local display panel only.

As per our finding, Ultramat 23 is not transmitting data to PLC. We have checked the communication between PLC and DCS which has been found healthy.

I need your support in the following queries:

1. What could be the possible reason behind this communication issue and mitigation plan to avoid in future?
2. What preventive measures can we do to increase reliability?
3. Which parts need to be replaced to restore remote monitoring?

Thanks,

Sohaib Manzoor

Hello SohaibManzoor!

I think this: https://cache.industry.siemens.com/dl/files/566/109741566/att_895514/v1/A5E37100388-003_ULTRAMAT_23_en.pdf manual can help you. There is on page 145 information about transmitting data via ELAN and Profibus. 

best regards.
