  1. Hi Everyone I am a bit of a newb and using a US57/ -B10-TR22 PLC with the current version of unilogic The short version of my question is: when there is a power off/ on when the PLC reboots does it start the scan from the top of the ladder or does it continue from where it was when the power went off? Is there a way to make it default back to the top of the ladder? My Long explanation / issue is I have a bit that activates a compressor - even though the bit is supposed to default to 0 on startup and i have a initial cycle set bit to 0 condition if i turn the power off when the compressor is running for about one second as the PLC is intialising the compressor will come on for a second I can only assume this is the time it takes the PLC to scan from where it was on power off to the condition that resets the compressor bit... It's for an aerospace application Any help greatly appreciated Kind Regards Tyler White
