Look at vemsv3.ini:
indicator = {status1 & 0b10000000}, "ALS Off", "ALS Sw On", white, black, blue, black
indicator = {status1 & 0b01000000}, "Launch Off", "Launch Sw On", white, black, blue, black
indicator = {status1 & 0b00100000}, "Shift-cut Off", "Shift-cut Sw On", white, black, blue, black
indicator = {status1 & 0b00010000}, "---", "Soft Igncut Idle", white , black, red, black
; indicator = {status1 & 0b00001000}, "IAC Off", "IAC On", white, black, green, black
indicator = {status1 & 0b00001000}, "Slot 0", "Slot 1", white, black, green, black
indicator = {status1 & 0b00000100}, "EGO off", "EGO On", white, black, green, black
indicator = {status1 & 0b00000010}, "---", "Trigger Errors", white, black, red, black
indicator = {status1 & 0b00000001}, "---", "ALS Active", white, black, red, black
and then in datalog definitions area:
entry = status1, "StatusBits", int, "%d"
So you must observe Bit7 is Yes in datalog.
But I suppose you cant count errors. It is like a flag. If error occurs flag switches on and stays until restart.
