  1. Working today with a V1040, I found something I was not aware of; complex HMI screens use a tremendous amount of scan time. I have placed 100 very small bar graphs on the screen with 100 very small bianary objects to create a graphic display of a process control profile. Whenever this screen is active the scan time will increase from 2 ms to 10 ms and this is not good for my application. I am trying to control a rather fast process with 100 profile points via analog output and 10ms is on the edge of non-functionality. Is there a way to slow the refresh rate on this particular HMI screen, so as to decrease the scan time?
  2. I am using a Vision 1040 with the Alarm server, when the trigger bit for the alarm is active the scan time goes from 3ms to 104ms and the screen flickers and the unit is unresponsive. Once the trigger bit is cleared the scan time returns to normal. I'm using a set coil for the Alarm trigger, and have only programmed 1 alarm so far, need to do 24 more?? Does the Alarm use interrupts to check status bits?? Any help or suggestions please Vision version 9.7.0 O/S 3.8 Bin Lib 0.3.10 boot 2.2 Attached pic shows ladder, MB810 is alarm trigger
