Pump Alternator on Computer Restart

We are having a serious safety issue with our Lookout process with two cities water systems. When the PC connected to the host has an error and locks up or restarts the software puts multiple pumps in hand rather than their position prior to the restart. Many times these lockups occur during programming the alternator object, but may occur at any time. These systems can run for weeks or months with no issues and then suddenly have multiple lockups and restarts in days. We are quite concerned with the pumps not maintaining their position upon restart as this poses the greatest safety issue. Any suggestions on how to keep the pumps in their original HOA position?

I have noticed the same thing using ActiveX controls. The only way I have found around that is to save the process with the pumps in the OFF position (or whatever postion you want them to be in on restart). If the "Save" command is not available, use the "Save As" command. This have been my experience anyway.

If I read your message correctly, you want the switches to 'come-up' in the same state that they were 'in', just before the PC crashed, restarted, etc.
 
If this is correct, have you had any success with using the 'state file'? This file will 'remember' what your process was 'doing', and the next time it is 'started', it will put your devices in to that 'state'. You might want to check and see how often you are updating the 'state file', as you can select how often it 'takes a peek' at your process. I believe that the 'update' interval (how often it 'takes a peek') has a range of 1 minute to 1 day. If you have a process that your operators are constantly 'using', you might want to have your state file 'update' every few minutes.
 
From what you are describing, it sounds like your state file is not being updated, and therefore it is starting up in the last 'state' that the state file was 'saved' in. (which has remembered the states you do not want your process to be in)
 
So, it sounds like you just need to 'turn-on' your state file update.
 
Ok, so what if you want something different, like you don't care if your system 'remembers' what was just going on. Instead, you need it to 'start the same way' every time, with these 'things' in this 'mode' and 'those things' in 'that mode'.  What you can do in this case, is to turn OFF recording 'state file', and when you get all your objects in the 'state' you want them to be in for 'start-up', you can 'save' your state file. Lookout will use this file and 'set' the positions of your objects on start-up. I would also suggest, you make this file read only, so it can't be accidently changed, updated, etc.
 
You can find this information in 'Modify Process' under 'File' menu. Go there, and hit the 'help' button, and it gives great info on this feature.
