set to 4 to invert the sense of IP1. If Flags are set to 0, then OP1 only
triggers when IP1 is high. The timing diagram is shown overleaf:
Delayed signal
A product sensor provides a signal when a product is present. This
signal needs to be delayed so that an inspection light is only turned
on when the product is present. The delay can be expressed as a time
period or a number of encoder counts. For example:
IP3 is the input from the sensor and OP1 is the signal to turn the light
»
on and off. OP1 has the same signal as IP3, but delayed by 500ms, or
IP3 is the input from the sensor and OP2 is the signal to turn the
»
light on and off. OP2 has the same signal as IP3, but delayed by 1000
encoder counts.
The two examples can be implemented using the following
configuration:
