6-5 Groups & Modes
Mode 3 - Outputs Gated by Group Inputs
D escription Outputs in a group assigned to Mode 3 are
on only while their programmed setpoints are
on AND the corresponding input terminal is
energized. If the input is off, all of the outputs
in the group will be off, regardless of setpoint
programming.
Applications Use this mode where outputs should be ac-
tive only while a sensor or limit switch is on.
Details • The group channel for a group operating in
Mode 3 has no effect.
• Each program in the controller can have dif-
ferent setpoints for output channels in the
group.
• MOTION ANDING and OUTPUT ENABLE ANDING can be used with outputs in a
group operating in mode 3.
• The machine position for a group operating in mode 3 can be set through GROUP
OFFSET programming.
Mode 3 Programming 1. Program OUTPUT GROUPS to establish groups and modes.
2. Use GROUP OFFSET to program the absolute offset value for the group.
3. Program pulses into the output channels in the group.
Mode 3 Example Application
In this illustration the glue head will operate only
while the photo eye sees the top edge of a
carton. Gluing will stop on crushed or improperly
erected cartons when the eye loses sight of the
top edge.
Mode 3 operation eliminates the need to hard-
wire photoeyes and other sensors in series with
the corresponding controller outputs. Instead,
the sensor is ANDed with the output through
Mode 3 programming.
