    attempted remote reboot of PLC no go
    accessed Hall and noted no run light on PLC cycled power no go
    no power to power supplies
    called Mark he said it looked like software in PLC was fried and to call Heidi
    Called in Heidi and she reinstalled PLC software and the controls returned however on ramp up of magnets power supplies both faulted

    Heidi reloaded the software from disk both power supplies rampped to desired amperage.
