Starting a Program
There are several ways to start a program. They include: Assigned Inputs, the IQ Master Run Control
Dialog box, Operator Terminal Fkeys, and Host Language Commands.
In all cases the following conditions must be satisfied before a program will start:
• The ULTRA Plus or IQ must be enabled.
• The ULTRA Plus or IQ must be ready (no faults exist).
• The ULTRA Plus or IQ must not be running a main program already.
ATTENTION
!
Understand the application before starting. A program’s outputs may
change state, resulting in machine movement. Failure to observe these
precautions could result in severe bodily injury.
ATTENTION
!
The user must provide an external, hardwired emergency stop circuit
outside the controller circuitry. This circuit must disable the system in
case of improper operation. Uncontrolled machine operation may
result if this procedure is not followed. Failure to observe this
precaution could result in severe bodily injury.
