I1-I4 and O1-O3 were originally connected to the thumbwheels (wire# 89, 91, 92, 93 & 97, 98, 99 respectively) as was VOUT (wire# 121). I4 was connected to relay contacts; the relay was turned on by a Twist Jog switch operated by the opperator. There was no connection to I6. I7 & O4 were connected to the plc.
