Delta HMI Historical Data Table & Trend Graph Basics

[@cadtechelectrical678]

1. when i make changes on my HMI through DOPSoft i loose my Alarm history, is there a way to avoid this? 2. I am trying to put a simple counter on my HMI reading a counter bit in my ISPSoft, but when i make changes to PLC programme i loos this counter value and it goes back to Zero, is there a way to retain this Value and only reset to 0 when i make a reset bit. any help would be appreciated
