Dear Experts,
We are currently in a project commissioning stage now of a Biomass Plant. The above mentioned CPU is used.
2 days ago, our load memory is only 42%. There were no major edits, only online monitoring and some bypassing of signals and adding some "always open" contact. When we checked the load memory again, we were surprised to see that it increased 67%. User memory is only 11%
I would like to ask for your opinion regarding the following:
1. Considering the minor changes, what other things could have caused the sudden increase in load memory?
2. Extra question, one bit, remains ON when the actuating switch is only momentary action and we are certain that it is not latching. I experienced this thrice (3X) already with Siemens systems. Because of the urgency, I wasn't able to find the root cause, only a work around. Now I'm experiencing it here again.
May I request for your technical opinion? It will be highly appreciated.
Thank you.
Ryan
